Re: Rear moaning over 55mph

Yes that is the pinion bearing in the rear diff. My Jeep recently had the rear differential pinion bearing replaced and it fixed the noise.

Oh well, if this moaning is by design I'll give up!

"By design," being a Chrysler technician-speak for "we don't know how to fix it."

Re: Rear moaning over 55mph

I mean they may have designed the pinon in such a way it is noisy, or they may have used a poor quality alloy that gets worn and noisy after a while.

This WE I drove for 500Km, gets really annoying, particularly for people sitting in the rear of the car.

2000$ to get it quiet again is very bothering too!
