Re: Driveline vibration

It's the same. Might be even better.

Re: Driveline vibration

I still have a case opened with Chrysler so I'll have to get that closed and completed before I open a new one. In the meantime, bump to the original post-does anyone have any idea what could/would cause these symptoms?

Re: Driveline vibration

What? There is no need to start another thread. This thread is still on topic.

Re: Driveline vibration

I would change out the diff fluid at another shop and use amsoil or mobil 1 instead of the mopar fluid with modifier, which is a low grade product. If the dealer has test driven it and can feel the problem, and refuse to do anything, and the problem goes away after you change fluids, show them the bill from the other shop, and demand a refund for the services they charged you for initially. THe other shop will be cheaper for labor and better fluid.

So much for the new thread, lol!

So you're pointing to the diffs being the possible source of the issue? You don't think it could be low or improper transfer case issue? As far as I know, they refilled and readded fluid to the front diff already. They probably never touched the rear though.

Problem is I can't tell from the vibration exactly where it's coming from. Feels like the middle of the car but I can't be sure. Does anyone know if there's a difference in symptoms for wrong/incorrect fluid in the diffs as opposed to the tcase?

Re: Driveline vibration

I would be very surprised if the type of lubricant used in the differential would cause a driveline vibration. I would think if the lubricant would be bad enough to do this 1) It would not meet API guidelines and 2) You would certainly hear the impending diff failure.

What is far more likely, IMO, (and something that I have seen a lot) is if during the service they detached the rear drive shaft for one reason or another and let it hang by the u-joints. This could damage the u-joints and would likely cause a vibration.

Was anything else done at the same time as the differential service? Perhaps tires rotated or put on in different locations? There are many things far more likely than gear oil in the diffs to cause a vibration like you speak of...I could be wrong, but i have never heard of a lower quality diff oil causing a vibration at speed. You would expect gear whine or howl, chattering during sharp turns, etc.

If it IS a vibration in the rear diff, swapping fluids isn't likely to help - whatever is causing the vibration is a damaged part (like excess play in the pinion).

Why would they need to disconnect the rear driveshift for a driveline service? Seems to me it would be a simple drain/flush(?)/refill job. Could be though... it was up there on the left for a while. Do we have any dealer tech's in here that can tell me exactly what the $360 driveline service job consists of?

Nothing else was done. It was supposed to be a simple driveline service as recommended by the dealer. They told me the fluid was black and hadn't been changed in a while... although it could have all been just an upsell, who knows? All I know is that as soon as I drove out I had these issues. They fixed the HORRID grinding/moaning during sharp turns by supposedly topping off the front diff fluid and adding additive, but this second issue has been harder to chase down. I will be going back there on Monday but first they're telling me that I will need to put the original tires back on. Thats fine with me...

EDIT: just to add a bit of descriptive info on the vibration itself - it isn't really like a wheel out of balance type of vibration. It's a very rapid vibration that could even be described as a very low frequency "humming" or "grinding" sound (thats how rapid it is). It sounds like this no matter what the speed. I feel it through the pedal but it is by no means extremely violent. You'd have to really 'feel' for it to notice it under your foot as it could easily be confused with the engine vibration. Power braking (holding the brakes all the way down while accelerating) does NOT reproduce it.

Re: Driveline vibration

The rear driveshaft is disconnected when replacing the gromet seal.

Same EXACT problem I have. The tech had my driveshaft just hanging there. When I got back in my Jeep right after the service, I immediately noticed the ticks on acceleration. My joints have been bad every since.

That does sound more like internal noise than u-joints or an imbalance. How long was it run with low diff fluid in the front? I would have them remove the cover on the rear and check for proper alignment and look for any scoring. The front is a lot more trouble to get to (since there is no cover), but if it was really low it certainly could be damaged in a relatively short amount of time.

Hopefully they'll do the right thing when you bring it in with original tires and try and figure this out for you.

I ran it for about a week and a half to two weeks before I was able to take it back (crazy work schedule). I'd say about 100-200 miles was put on it during that time.
