Hi Guys !

My XJR '99 has a fair amount of pinion play , felt when breaking<>pulling up.

I double checked if it was the diff by turning the driveshaft by hand , clunking noise came from the diff.


Question ; is it possible to adjust the play with the two rings on both side's of the diff (see picture) without opening ?

If so ,what is the right procedure ?


b.t.w. my diff is still on the car , the picture is from some market-site



Thanks !!!


Marcel

No you cannot, and pinion bearing preload is set on the pinion nut after removing the driveshaft and jurid coupling. You need some amount or slack or youll burnup gearsets and have alot of whinning before you do.

 

mmmm , that's to bad ..


i was hoping for an easy fix


But are these ribbed rings for adjusting backlash on this diff anyway ?

Correct me if i'm wrong ,but after some more study it seems the ribbed rings on the side of the diff are there to adjust the camber ...

 

yes adjust those and your diff will get really noisy. Those are to adjust axle bearing preload
