Hep with buying used Dodge diesel

[KFhunter]

I have an 06 manual and it is amazing.  160K and still running strong.  Can't go wrong with 05, 06, 07 (early) vintage.   

G56?

Not sure....whatever came stock in it.  It is 100% stock minus the leveling kit.   Not a huge gear head so so not 100% sure what clutch is in it.  With that said, I have never had a problem with it.

read this jrebel if your transmission is aluminum.  A quick peek under the truck should tell you.

If your transmission has a whine then switch to manufacturers recommended 75w90w gear oil.  It'll extend life and kill the whine.
actually switch anyways,   ATF+4 doesn't belong in a manual transmission, all for a very slight MPG boost.

Ive had 5 dodge cummins 1990 auto and then a bunch of sticks 98 &01 5spped and currently 03&056 speed.
The older autos are garbage but I really liked the all mechanical 12 valves. The 24valves were ok. The key to making the tranny last was not to pull in 5th gear. I spun the 5th gear off 3times on the last one. Every 30k. Even welding onto the end of the shaft didnt work. The surging with all the weight is what killed them. I would haul 16k behind the truck for at least 100k miles a year on them rarely disconnecting the trailer. I personally think the 04-early07 are the best vintage with the stick. Im gona keep rebuilding my 2 current ones until its no longer possible.

Fairly safe to wager that out of all the people that will read this post, there may be 1, 2 at most, other people who tow like you do.
Under the conditions that most use these type trucks, they'll never have that issue.

I used to drive more than that, but that is how many miles I put on each truck!  I was having the argument with my brother who was looking at purchasing a gas work truck. I couldnt uderstand why. I guess you 2 are both correct because I have worked my fair share of dodges at capacity or slightly over for a Loooong time.  Ive gotten a little smarter, ive hired  semi trucks more when possible.

I have a 2004.5 bought new in June 04 with nv5600 tranny. Been running fine since then. Steering linkage replaced early on, a few u-joints, water pump, and turbo waste gate actuator wire is about all I've had to do. Rear brakes done but the fronts are still stock pads and all. Not done any heavy towing though, heaviest was horse trailer with a couple horses and vacation gear, hay hauling and some firewood a few times.

all of what's said above but want to add

look at the exhaust manifold for an EGT probe, usually a hole drilled just in front of the turbo in the manifold itself and a probe installed.  Does the manifold look reddish and brittle like it's been red hot a few times?  Or dull looking.  Look at enough manifolds you might see some differences and can spot one that been run very hot quite a bit.

While your in there pop the rubber hose off the front of the turbo, the intake boot, and (if engine is cold and off) grab that nut on the turbo and give it a wiggle.  Shouldn't be any play up and down at all.  You might feel a tiny play in and out but if it's wiggling up and town it's a bad turbo just waiting to blow up.  Carry a screw driver with multiple tips in the handle.

next take the oil filler cap off and set it where it won't fall and start the engine, is their white smoke and air blowing out of the oil filler cap hole?  It's got bad rings and excessive blow by and needs rebuilt engine.  There shouldn't be enough air coming out to displace the filler cap if you just gently set it in the hole but don't screw it in, should just rest there vibrating with the engine but not blowing back out.

after you shut off the engine and replace the oil filler cap crawl down under the front bumper and start wiggling steering arms and components, should all feel solid.  Check the u joints in the 4x4, not a deal breaker but you might find some bad U joints while you're under there.

I think your backwards on your turbo shaft play. Some up and down (radial movement) is okay. Holset specs for a HX35 is 0.013 - 0.020 for radial play. For axial or in and out it is 0.001 - 0.005.

You can find tolerances for Holsets HX and HY lineups here: http://www.holset.co.uk/partsservice/service/HX_Service_Data_Sheet.pdf

Wow Guys Thanks for all the input !!!!!
Greatly appreciated

[lewy]

I had an 08, everytime I turned around it had issues. The engine/tranny were fine but everything else was junk

[bknilvr00]

Managed to luck into an 07 2500 with 6 speed manual. My only complaint, is the friggin DPF bullcrap. To buy a delete tuner its like 1200 bucks. The exhaust is cheap, but the epa banned dpf delete capable tuners. So now its a limited quanitity. All i can do now is wait till guys run theirs into the ground and sell their used tuners.

What years did they have issues with cracked blocks. Seems like they were cast in Brazil. And we're cra king by the motor mount.
