rearend problem

[urabus]

on my 92 XJ 4x4 when you come to a stop sometimes the rear end makes a noise like its lurching forward. This happens only on more sudden/hard stops.

What could be the cause of this? at first i thought it was the u-joints but there is no play in the drive shaft. I have also just changed the rear diff fluid. Thanks in advance for any help.

Are the rear brakes locking up for whatever reason?

 

[urabus]

no.. just the rear end sounds like its shifting under harder braking.

Is there a bracket, bolt or something that commonly goes cauing such sounds?

check the leaf spring bushings... if they are sloppy, the whole rear end could be shifting..... also check the shocks/mounts.

Its your slip yoke on the rear drive shaft, take off the cover and re-grease with a industrial motor grease. It sticks together under hard braking.

Give it a try

I have the same thing. Happens ONCE in a WHILE for me. But, my dad's 1996 is evident EVERY time you brake.
Would be interested in a 100% fix on this.
