How To Find Suspension Noises 101 - EricTheCarGuy

Jun 06, 2021
Hey kids, Eric the car guy, here today we have a 2005 Acura TL. I know Eric with another Honda, but the principles in this video applied to many vehicles and situations because this vehicle has what the owner believes is a

suspension

noise and I've gotten a lot of requests from you about you know I have a noise that kind of thing well this will help you identify a

suspension

noise and that's the purpose of this video so the first thing we do if it's the car From a client, of course. It's your car, you know when the noise happens, but you need to get in the car and take it for a drive and see if you can reproduce the noise, so let's go drive and see if we can hear the noise, one of the first things you should To do is try to identify the type of noise, is it a knock, is it a squeak, is it a squeak.

I mean,

noises

come in all shapes and sizes, but they can tell you if you know a certain component or area to look at, if you have something like, for example, a noise in the steering, like when you turn the steering wheel. , you hear some kind of noise like a rusty hinge or maybe you hear the belts squeaking, that kind of thing, it's better to listen to that. noise if you're sitting still, so start your checks by simply turning the steering wheel from side to side and I'll quiet down so you can hear. I don't hear or feel anything abnormal here when the steering feels a little, no. nothing here is okay now let's drive now I can hear it a little bit there now the owner says this noise is coming from the right front not okay how well is that microphone going to pick up that a little annoying on this bumpy road well we did a trip, oh there is a lot, I also see how the steering wheel moves if you move at lower speeds, like that, that is a problem with the tires, or it is a wheel, something is not round, so the tires are always suspect .

how to find suspension noises 101 ericthecarguy...

I'm just driving normally, I don't seem to hear the noise, okay let's turn around and go back to the store, okay, here we are in a quiet parking lot and I was actually hearing it a little bit and we're not even going over the bumps. play a little miniature golf of course I won't do that now we're just going to try something real quick while I get out here and that's getting hard there was a bubble also pay attention when it breaks there's a noise when it breaks. there is a noise when you change direction when you go from Drive to Reverse there is a noise so the idea is to do as much testing as you can to try to

find

out what duplicates the noise so is it like I said a change of direction whether go? from reverse to drive is when you're turning the steering wheel it's going over potholes it's going over a lot of potholes it's going over only big potholes it's going over potholes when you turn the steering wheel is it doing? a noise only when you are turning the wheel it is a clicking noise the noise of a knock this is a grinding it is a noise like a rusty hinge with all these things they can give you a clue as to what you are looking for but i think we are going to get our best results when we take this to the workshop.

Now we brought our TL to the workshop. Let's start shaking it, rocking it and rolling it. Let's start looking for loose parts. I started by opening the hood because I like to drink. A look at where the struts mount on top along with any of the other things underneath and around that could cause a noise. Okay, now let's open the hood and what we want to do is I like it. I can't really see the upper strut mounts on this, but I can hear it in that area. I removed these covers, but you may not need to start with that, but what you can do is just push the car, move the suspension, and see if you can get it to work. the noise i actually hear it right there hello leave it in my head be careful with these bullies sometimes they don't like to stay awake and if that's the case i have a little trick for you as we know our noise ended in this area, let's raise this wheel with a jack, now we have the wheel off the ground, we are at its level.
how to find suspension noises 101   ericthecarguy
I only have it on the jacks, so you don't want to be under it, but grab the wheel at three. and nine o'clock and we're going to go back and forth, grab an upper and lower movement here, move it around and what you feel are loose pieces, okay, I've got it resting on the subframe now that we're under here, but these are the parts you want to look for, you hear a rusty hanji type of grinding noise when you turn the steering wheel or sometimes when you go over bumps, ball joints are a big cause of things like that, so when you push the steering wheel up and down front and back, you might need a partner down here to see if there's any movement here where this boot has some suspension systems;
However, when you lift things off the ground this way, it will actually load the kneecap, you won't. be able to see any movement in cases like that what you need to do is put the jack under the control arm and you know different systems require it in other words just do this check anyway no matter what but look to see if when you put the weight of the car on the actual suspension and lift it under this control arm, take like a lever and put it here and cut, lift, lift to see if you have any movement in this area and then try it like this and try it once with the jack under here if you don't have any movement there, you don't have any movement there, that's one of the places to look next, you want to check your tie rod ends right here and that's the that disconnects from the power steering rack and you want to look up in this area and you want to look up here and when you're moving the tire back on that side to side this is where you're going to look for movement but look for movement here or sometimes here if the moves back here is an internal tie rod if the moves out here is the outside tie rod watch the power steering rack video and you'll see how to do each of those things.
If you remember from the video of the element that I made the stabilizer links, you want to make sure that these guys here are not loose, broken, these are the attachments. style of links, but some of these links are like stacked bushings, things like that and I've seen them break quite often so you want to make sure you might even want to put a lever in here because sometimes, especially these ones that are sealed . This way you won't see the movement so you'll have to put a lever down here and move around, really move the bar and see if you hear or feel any clicks, if you don't then you can control them.
Take the control arm bushings out so look at where the actual control arm meets the body and look for any movement there, sometimes you can see movement or something in that area which is somewhere else and back to the direction. Sometimes I have seen the supports. In the Pontiac video I have sometimes seen the actual power steering rack mounts loose or cracked on the subframe and in that case it would obviously be a different type of repair if it clicks on the turns. CV joints are big. for this with a front wheel drive car, if you are turning right and you hear the click then it is the left axle, if you are turning left then it is the right axle, that should help you identify it if you don't see it. a split boot or something sometimes you'll get a remanufactured shaft, it's not as good.
Another place I want you to check are these other upper control arm bushings and ball joints. Sometimes you can squeeze them and you will see movement here, but when you move the tire in and out you will see some movement here, also the bushings on the back where it joins the actual body, are also suspect, so it may be that This whole arm starts to move. Next look at the coil springs, you might see a broken coil or something. You'll also want to take a good look at the strut itself. If you see any oil residue on the outside of the strut, then the strut is probably defective because it is full of oil and once the oil starts leaking, they don't cushion like they should.
In some places these shock absorbers are now called. Lastly, if you're having real trouble

find

ing the noise, you won't find loose parts like I can't find here. Here's something I want you to try: you're checking everything that moves in the suspension and if you're in a position like I am now where you've checked all the suspension parts, there are no leaking struts, no broken coil springs, no loose balls. The joints do not have loose upper ball joints and there are loose bushings on either control arm. The internal and external straps are fine. The shelf is apparently fine where it is and you're like, "What the hell, I hear the noise and I." I still can't find where it is.
The road simulator simulates a bumpy road and hits the tire with the hammer, but hit it like on the tread like you would if you were driving down the road and hitting a bump or something, you become the bump. and then listen around the suspension. A lot of times I don't hear the noise at all, what I find when I do this, I raise my hand and put it on top of the clamp and that's what I'll do for a while. I'm hitting things because I like to grab different components if I hear the noise and you'll really be able to feel it when you hit the tire.
I really should have put on my safety glasses to keep the dirt out of my eyes. I don't really hear the noise, but this guy here will help you find the rattles and things that are in here and if they take you, even better because you can really swing them well and swing them like you don't. just do it like on the tread, do it on the side, a little bit, hit it there, hit it here, hit it, hit it everywhere until you can really get the noise to resonate, you do that and then you just put your hand on the part suspicious and You will feel the noise, you will feel the vibration that it is making.
Well, something else. I forgot the strut rod bushings. These strut rods go from the center support to the lower control arm and practically keep the lower control arm located in a certain place if these bushings go bad you will hear a clunking noise when accelerating or braking and just when you have that forward movement forward or reverse and this is what it looks like outside of the car, but and this is actually for my clutch video from If you can, you can check these bushings and if they are faulty, that could be responsible for a clunking noise, so Make sure you check as many parts of the suspension as you can and try to move it as many times as you can before doing so.
You're done, we shook the suspension by hand, we pried it up with a crowbar, we looked for leaks in the struts, we looked for broken coil springs, we looked for broken parts, another thing I want you to do. What you want to look for is anytime you see a bra with orange powder or any cap or anything like that with orange powder around the outside that it's a loose piece because a lot of times what happens is any component that's loose we'll get a little bit of moisture. there it will start to rust and you have a movement where rust will come out, so it's a good indicator that you found your noise if you see orange dust around the outside of, say, a bolt or a bushing or or something like that, but now that I haven't really heard it, I heard the noise when I was rocking the whole car back and forth, I'm starting to suspect something else so I'm going to remove these plastic covers to take a look. on the upper strut mounts that are under this tie bar up here, but wait a minute.
I think I just found the noise. I haven't seen this very often because it has to be pretty bad to get to this point, but take a look at this engine mount. I saw the cracks to begin with when I pulled the rubber back. See all the shiny metal. Look at that and you can see this piece of aluminum is sitting right on top of here and I bet you if I put my floor jack under this it would lift up and come out of there because I don't think it's an engine mount. Nobody notices that I'm just moving the engine by hand.
You're going to lift the cat. oil pan with a block of wood between the jack and the oil pan, okay we have our jack in position, yeah yeah that shouldn't happen so the destroyed engine mount is the cause of our noise comes from the right front, it's not really a suspension component, okay? No, this is not a video on how to replace engine mounts, it's a video on how to find a noise, but here are the points, take it for a test drive, listen for the noise, listen for anything specific. turning the wheel is just driving on railroad tracks just driving over speed bumps this happens slowly it happens quickly it's like a rattle it's like an explosion it's a bang it's a thud and then don't forget either that there are wheels in the back too, so it's easy to come from there, something that I would also like you to try and I'll show you real quick, now here's another weird one that I found that might help you.
Here's another check if it had a rattle or noise in the past. I have had cars that were rear-ended or had defective exhaust systems.originals. These things are on rubber hooks, so this is going to move, so some of these are going to move quite a bit. a little bit and you can take the entire muffler assembly, but just take the muffler assembly and shake it back and forth because sometimes where they mount on the rubber mount, sometimes they brake and like I said, sometimes the components They bend themselves, but I have seen on a couple of occasions that it was actually the exhaust that was bouncing causing a noise that someone thought was a suspension.
The problem is fine, so here is our old engine mount. We don't need any stinking engine mount, as you can see it's destroyed, so let's take it for a spin and see if our noise is okay. Here is the moment of truth, yes, no more noise. Plus, one last thing I'd like to mention before I let you go are the tires. I know I talked a little about that wobbly steering wheel earlier, plus you need to make sure you have the proper pressure if your tire pressure is too low every time you make a turn you'll sound like you're in an episode of Starsky and Hutch and if they are too high it will bounce like a basketball everywhere, so too high pressure will cause the suspension to work. much more because the tires are going to bounce very little pressure in the tires will cause the tires to rub quite a bit, especially on concrete, when you are in the parking lot you will hear much, much more squealing and normally, those are things to keep in mind as well Note and watch the video on wheel bearings to detect that noise, but something to keep in mind with that noise is not always a wheel bearing;
In fact, many times I find that that is also a problem with the tires, so if I have abnormal tire wear, that is another thing to take into account. Run your hand across the top of the tire and feel for any high spots or abnormalities. It should be relatively smooth. I mean, not so smooth that there's no tread left, but. Know that your hand shouldn't be caught on something, if so it could represent an alignment problem or something going on with a suspension that is affecting the alignment and causing the tires to wear unevenly, but the uneven wear of the tires could also cause a slight whine. you're driving down the road so keep that in mind but it could also be a wheel bearing and what you do to confirm that is just change the tires, like take the front tires, move them to the back and then take them to another one.
Drive if the noise changes or goes away you know it's a problem with the tires but if it stays the same then it could be a problem with the bearings and watch that video on how to proceed there are a couple more things I thought about since then , Alright. Getting back to you Eric, I have also seen situations where someone had some things in their trunk that when moved made a lot of noise. It's amazing the things I found in people's trunks. Actually, I'm a little scarred by it. The main point is to look for loose things, look for that orange dust which is an important clue, use that hammer that hit that wheel, try to reproduce that noise, don't rule out the brake calipers, if you hear a noise from a brake caliper that I have repaired them and sometimes it's the brake pads, some brake pads are better than others, some brake pads are a little loose, if that's the case they will vibrate inside the caliper when you hit the bumps, I've seen it a few times and usually I start with maintaining them and If that doesn't work, I usually end up fine, let's put it this way, if they are really cheap pads, I recommend replacing the pads from there, look for missing shims in the brake calipers, if those shims are missing, Yes, things will work out.
They rattle so feed those shiny little pieces of metal that need to be there on some tweezers, not all tweezers have them of course if they are missing how would you know which pieces of good question guys should know? You should check with him to see if there are supposed to be any. There will be shims there because many times they come with a new set of brake pads. Shake the wheel from side to side, up and down. Look for loose ball joints at both the top and bottom. Look for the casing. Look at the bushings where they join. body for the control arms both upper and lower look for broken coil springs honestly broken coil springs don't usually make a noise what they do is affect the ride height so if you have a broken coil spring the car it will have a tendency to lean that way with a broken spring, so if you have a car, you look to the front, it has Detroit lean, then you might suspect a problem with the coil spring and if it's not broken, it could just be old and sunk. people are heavier than others there, a little harsher on the suspension and it's usually on the driver's side where you'll see that, particularly if you're going to put it on a lineman's track and you notice the numbers are way off on the camber, The only way to correct that is actually to replace those springs because the springs control the ride height.
Let's do a full suspension video. Now that the wheels are trained, at some point we'll talk about the different parts and what they look like. on the shock absorbers, the shock absorbers rest on whatever you want to call them and check that they don't leak, if there is any oil leaking from them it's a good indication that they are in bad condition so you won't necessarily hear the noise like we might hit the tire or anything, but if you see leaking struts that leave an air pocket inside the strut and the strut will knock internally, also check the nut, the nut where the top of the strut goes through the neat upper strut mount, look that nut I've seen times where the bushing that the strut goes through inside the upper bracket will come loose and rock back and forth, that was a part about bouncing the car and rocking it back and forth and so last, like the cradle bolts, like the entire subframe at the front. -On wheel drive cars, in particular, there are times when you have to remove the entire subframe, like to put in a transmission or an engine or something, and let's say someone was in a hurry and they didn't tighten the whole thing. everything or you know, for some reason, those aren't tight again, look for that orange dust that's usually a good indication that you have a loose zipper, something like that.
I have cured the

noises

by just closing a bolt, but you have to be. thorough, you have to be methodical and you have to pay attention to the ball joints, they also sound like rusty hinges, especially if you like the first test we did, just sitting there, turning the wheel back and forth, you hear a rusty squeak. type of hinge noise, then place your hand on the ball joint, like if you put the car down, ask a friend to turn the steering wheel back and forth and just place your hand, unlike the lower control arm, and feel around the kneecap, hold your fingers. of those moving parts, but you can usually feel where the noise is coming from and the closer you get to it, lastly, chassis here, we talked about it before and found a noise.
In fact, I have had to spend days sometimes placing chassis here and in different parts. of a car's suspension parts to try to figure out where the heck that noise was coming from. Those were difficult. Those were really difficult. So there are some that will be hard to find in this one. This one is a bit complicated. I'm glad I saw this because I don't discount those engine mounts and it was interesting how it acted, it didn't necessarily make the noise all the time but more or less when the engine revved up. opportunity to rock back and forth and ride that saddle so it was good to have the information that I have on this so I'm Eric the car guy you can always find me at Eric Carr Gomm or follow me on Facebook. and Twitter, you can visit me on the forum.
We talk about things like this a lot and how we solve them and how I solve people's problems. It is a good moment. Be safe, have fun, stay dirty. I will see you later.
