I am getting a driveline squeak in first, second and third gears at vehicle speeds below 20mph.

The squeak gets faster as you accelerate but is not engine rpm related.

does it when the driveline is warm...not cold.

Seems like it is coming from under the center to the rear of the truck somewhere.

I was wondering if any of you guys had experienced a similar problem?

I went under the rig and silcon sprayed everything that moves. Tried to wiggle the driveshaft and inspected the U joints. Everything seems tight.

Going to DC in 1.5 weeks with the backlog at my local dealer and was trying to figure out what it may be before hand.

 

Squeak gave up and turned into one nasty as all he|| vibration.

Coincidently it happened just as I was passing the dealer ship so I only had to turn around and drive it 200' into the lot.

Unfortunately I called them this past monday and the earliest they could schedule me in for a LOF and diagnostic on the problem was monday next week (can you believe that?).

Anywho. Here is for hoping I am under the 7/70 powertrain deductable and the thing will work better.

I was playing with it trying to figure out the problem when I would put in in 4wd it would make one nasty raCKET.

I am pretty much thinking it is the rear bearing in the Xfer case or the driveshaft U-joints. Couldnt be much of anything else I gander.

 

Dodge dealer was quite ammicable on my situation.

They did the LOF and called me that they couldnt replicate the problem. - no problem I drove right down.

I drove it up the backlot hill behind the building and on the way back down it let out one heck of a vibration at less han 10mph. Tech said he'd pull it in the garage.

I explained what I investigated and he did the same.

He called over the Service Manager (real nice guy) and they talked it over. He said everyting is tight and they dont know where the vibration is coming from and that they'd check it out closer tonight after hours and get back to me tomorrow on a course of action.

Gives me a good feeling.

PERsonally I think the rear bearing in the back of the Xfer case let loose. My driveshaft really wiggles back and forth on the center of the output shaft. It is supposed to go in and out I know...but back and forth?

 

my guess would be a u-joint. drive around a little bit and then get under the truck and see if one of them is warmer than the rest, when my last one went out thats the way i found it because i caught it before it got loose,

 

Good Trick.

Will have to remember that.

The rear U-joint is leaking grease from one cap.

Personally I think the whole setup is one big failure. I always had a little sporadic vibration. Then the squeak in the last 500 mils and now a pronounced vibration.

One thing always leads to another.

But thanks for the tip. I like adding feathers to my cap.

 

Seems they are on national backorder.

Was wondering if there are any other answers...
