look

ing for a backup truck to pull a camper with or something of that nature so I really want to start with engine on this video our normal protocol is interior/exterior drivetrain in the engine but I'm going to start with the engine because I want to make sure that everybody that's watching this video especially if you're shopping for one of these trucks watches this first as most of you all know the 5.9 is a really really good motor trotting through the common-rail version of this motor it's it's it's one that you can have internal failures of this motor that you have to be aware of as a purchaser of these vehicles now again like I said we see a lot of these trucks come in that are bought by young guys young gals that are wanting diesel trucks they find something inside their price range so they get one of these trucks and bring it over for us to take a

the common-rail inside here if you have a common rail failure on the injectors it can absolutely wipe out a cylinder another thing that went on with this motor was the new turbo orientation is towards the back of the motor four five cylinder so you're usually gonna have a

problem

at those cylinders there because you have a combination of the heat and if you've had a if you've had a injector

problem

it gets even worse on that side of the motor so let me show you a very easy bare-bones way to check to see if this is a truck that you want to park just so we'll stake the hypothetical situation this is an old five truck you're

look

ing at it it's in your price range take the truck out drive the truck drive the truck and get it to operating temperature if you're

buying

the truck from anyone and they won't let you do that then walk away from the truck take the truck out getting those operating

wanted for the platform for our pulling truck guess what it had it had a Down motor in it it had a down cylinder area - actually had two down cylinders in it it wasn't wouldn't a mat it was a sort of a mast thing you wouldn't have known it unless you drove it got some miles on it got it up to temperature ain't and saw the amount of blow by that the truck had so injector failures on this motor or another thing you know you're

look

ing anywhere from injectors for you know remands or 250 dollars all the way up to brand new injectors are a little over 400 so if you find one that's got a down injector or it's got some

problem

s in it maybe it's got a tick in the motor or something those are all things be relative of another failure that are be aware of another failure that happens on these trucks is that drop valve seats you got valve seat choose a head up so if you've got one that's just any sounds it doesn't sound natural to you blow by you've got to walk away from the truck or you've got to get it into a price point to where you can repair the engine and and go on about your way if you go you do the things that we talk to you about on daily basis fuel quality making sure you're watching your eg T's and just be a conscious dry then you're not gonna have any

problem

s out of these trucks but if the trucks have been ab

used

it will show inside of the motor so wanted to talk about that especially to you young folks that...

are out here

look

ing for trucks be aware of this don't jump out here and buy the first truck you see make sure you know what you're getting into because if you get into a truck knowing you can't afford to put a motor in this truck it can be a really really bad deal for you all right let's get away from motor I can't do it Adam wants me to turn around tell you leave a comment leave a comment below tell us about your truck tell us about any experiences you've had anything that you can do to help your fellow truck owners please do that in the comments here here wherever the hell they are drivetrain oh three 207 platform actually had let's see four different versions and transmissions in it will talk about transmissions first let's talk about automatics the automatic in these trucks forty-eight re forty-eight re s if we talk about a lot got a bad name yes there can be

problem

s with this truck if it hasn't if the previous owners haven't you know adjusted the bands on it if they haven't changed the fluids change the filters banged on them you know didn't have proper fluid level coolers plugs so on so forth different things they can be troublesome for you lots of products out there for forty-eight re transmissions to be able to safeguard you from some of those things but you know if you drive the truck and the motor sound or you drive the truck and you notice some slippage or some shuttle shifting or any of those things just be aware...
of that and try to work that into your purchase price or if you decide that you're going to purchase the truck there are actually three different manual transmissions that were in these the platform of truck oh three oh seven oh three oh four some of them had a five-speed Envy 4500 transmission in it that was actually a D rated motor is a 250 horsepower motor that's a you know that's a good truck if you put a tuner on that truck that automatically takes it up to you know above what the above the horsepower anyway so really that kind of negates the whole D rated motor because they've got normal 305 injector if three injectors in them so there was MV 4505 speed on on some of them NV 5600 which we've talked about a few things not a lot of

problem

s the NV 5600 sometimes some sync girl

problem

s clutches in them or single disc single mass flywheel those can don't hold a ton of power if you're above 400 horsepower he probably won't slip the clutch on that and then we've got the G 56 the g56 was in the oh four-and-a-half 207 model years and they're in there in the six seven trucks to the G 56 Mercedes transmission all in all a good everyday transmission it doesn't hold tons and tons of power there are a lot of guys out there that are on thousand horsepower on those trucks on a stock transmission the weak link on the G 56 trucks is the clutch system it's on dual mass flywheel a lot of

problem

s out of that so you're gonna be

look

ing...
at a clutch change on that one again above 400 horsepower but all in all you know good transmissions with the introduction of this truck the O 3 model year

dodge

went over to American axle so you've got American axle up front a back really don't have any

problem

s with the axles themselves the differentials themselves just don't see a ton of

problem

s with those but you've got the same

problem

s that you did in the Dana axles axle trucks u-joints failures are just about the same in these vehicles the front ends on this truck really not any different you know we talked about how to see if I've got front end

problem

s you just take the truck turn the truck on or turn the key on on the truck to where you can take the steering wheel and move it back and forth between the bumps and when you do that you want to

look

underneath of the truck and

look

for weak links and you want to

look

for Tyrod movement track bar movements you know if you want to jack it up and check the ball joints on the truck I showed you how to do that the

problem

s that we talked about in all

dodge

s are still here on this model trucks and just be aware of that yeah I think that just about covers driveline let's talk about exterior exterior they didn't really get a whole lot change

used

on the

dodge

paint jobs or the body panels bought the paint jobs you still got some clearcoat

problem

s you this is Adams truck you can see he's got some clear coat

problem

s there on the high side of...
that sorry about rub he dust at him this truck was actually repainted at one time common rust spots rocker panels are bad about rusting top of the bed sides here usually bad about rusting you can see that this has actually been bondo didn't do a very good job of blending that in anyway Adam and I were talking about that this morning but that blend right there is probably a byproduct of the rust coming back through honestly that spot right there I would think so that's probably rust you know rusty body panels on these trucks another thing to be aware of especially you northern guys I don't feel like the undercarriage of this truck really rusts any worse than any of them again depends on your location with the rust interior not as eventful as the second gen trucks same same stuff you see on interior here seat corners are usually beat up just a little bit you know as far as a/c system goes you don't have the

problem

s with the blen doors like you did in the second gen trucks the dashes are you know pretty good sometimes have a few gauge

problem

s we see inside them stepper motors and the gauges and whatnot going out or but it's all you know pretty normal stuff but tell you one thing that we see a lot of failures in the interior on these trucks is if your trucks got power windows and the power wind is not working even if it's in the front or in especially the back windows what we find there and so if you've got a back window let's just say Ford or...
truck your back window doesn't work before you go to changing out switch panels which now let me talk to you about these switch panels just a minute this power window panels don't think that these don't go bad but before you throw X amount of dollars at a at a power window switch make sure that you check the wiring going back this don't want okay both these doors this wiring harness here I don't know why I have taken these apart before and seen just absolutely messes of wires being cut there's nothing in here that actually pinches them I don't know if there's a tension

problem

with there but you can pop that grommet out move it back and just check the wire harness so again before you throw a switch at it make sure that you check your wiring harness make sure the circuits are complete in the in the power window system and that's pretty much it I feel like I've touched on all the bases that really just you know if you just pay attention to what I've told you about motors I've seen guys I can't tell you how many young people we've seen buy trucks and start having a

problem

start noticing loss of power old consumption ticking and then bring them into the shop and they got a Down motor and you know then immediately it's just a it's just a bad situation for them both financially and personally so they are good trucks you just have to be aware of the failures that you can see inside this platform so I'm waiting for...
