vibration @ 1700 RPM

[yycguy]

Hi,

Hey guys can anyone maybe help me out. I am getting a sort of vibration coming from the drivetrain at 1700RPM it happens only when in motion and more noticable in Overdrive. It is one of those noises/vibration that I can feel though the steering wheel. I seems to be there only when crusing and not under load or decel. You can see from my signature what mods I have. I have checked the engine exhaust for anything loose but it all seem secure?

Any assistance would greatly be appreciated.

Common problem with 3rd gens. There is a TSB (don't remember the # but you can search for it) on this. The vib is in the PS hose. The TSB is to install a weighted hose that dampens the vib. I had the TSB done on my '03 and it resolved the problem.

I had the "Drive Line Vibration from Hell" between 68 and 78MPH on my 2004. 5 3500 4X4 dully. They re-indexed the front driveshaft. Good luck.

I had the steering wheel vibration and it was corrected by TSB #19-008-03. The vibration on my truck was in the 2000-2200 rpm range, which was a little higher than yours. One thing I did when I first got the truck was to put the truck in neutral and let the engine drop to idle when I was at highway speed. The vibration would stop when I did that, which led me to believe it wasn't a driveline issue. Hope you can track it down.

Mine was a vibration between 70 and 78 mph turned out to be the front drive line.

front drive line?

I've been going nuts trying to solve the vibration thinking it was the rear, why is the front turning if you aren't in 4 wheel drive?

Can you run the truck with the front driveline removed?

I have 2000 miles to go before I can get home but would love to get rid of the vibration now

Thanks guys, I will check into these areas and let you know how I made out.

Hagar:



Our trucks don't have automatic or lockout hubs, which means everything is turning on the front end all the way up to the transfer case whether you're in 4-wheel drive or not. There are arguments both ways whether or not this is a good thing. Personally, I would prefer lockout hubs and there has been much discussion here about finding somebody who will make a reasonably priced aftermarket lockout hub. It's probably do-able driving a short distance without the front driveshaft, although I wouldn't recommend it anywhere close to the distance you're talking about for all kinds of reasons. I once had a 73 GMC and was in the woods and stripped out the rear axle splines. I dropped out the back driveshaft and drove it home about 60 miles in 4 wheel drive, which meant only the front axles were doing the pulling. Everything I ever read said never, ever do that but when you're stuck in the middle of the woods with night coming on... . well, you gottas do what you gotta do. Fortunately it didn't seem to have an ill effects on the transfer case.

Yup they turn all the time. Remove your front driveshaft and drive it.

Although I do not have this problem, reading so many posts regarding this is disturbing. There seems to be many different reasons for the vibe, some have posted that after many visits to the dealer, thay have been told it can't be fixed, and except for the weighted hose (which seems like a mickey mouse solution), DC hasn't been much help. What the hell is going on when a major international vehicle manufacturer who must have some good engineers can't figure this out.

I too have the dreaded vibration. For me, perhaps the bigger question is why DC took $47K of my money for a vehicle they knew had a problem. My dealer has been very good about it and even got a tech trouble shooter down from DC to check out my truck and one other that had the same problem. They did the drive train realignment and pinion angle adjustment to no avail. It changed the problem somewhat but did not improve or fix it. Here in Ct we have to initiate the Lemon Law process prior to 24 months or 18,000 miles. At 8,000 miles + now I have to start the process soon. Reluctantly, but I can't accept this vibration. I just got back from vacation where I was driving 10 to 15 mph slower that the average traffic because of it. Do love the Cummins though. For me, it is the primary reason for buying Dodge and the reason I would buy another. I'd just take it on the hwy before forking over another 1/20th of a million dollars.

WStoops, As long as we go along saying "For me, it is the primary reason for buying Dodge and the reason I would buy another" I don't think DC should be too overconcerned about fixing a vibration problem. I'm gonna hold on to my 98, because DC still ain't got it right !

Ron,

Thanks for the response. I hadn't looked at the issue from that perspective before. You are, no doubt, correct. DC's selling of vehicles with seemingly unrepairable problems is a really bad business practice. Even great techs can't correct a bad design. :-{} In my travels and meeting other diesel owners, both models F and C, It seems the F guys are pretty happy, the C or G guys less so. DC probably won't address this issue until they feel it in their pocketbook.
