Rear Diff Bad Sounds

(1/2) > >>

Jeff J J:
Hi all my rear Diff started making very bad sounds  :(. I have had to replace the rubber coupling twice in about 3 months and now after driving for about 8 miles there is a loud knocking sound from he rear. I think this could be the Diff on the way out any one got any other ideas  :-k. Jeff

lee celtic:
what are your hardy splicers like???

any play??

andyb:
As Lee has said ^^^ check the UJ in the rear prop. It is better to remove the prop shaft to check for UJ wear. Warning!! Make sure that you put the centre diff lock in or else you won't have any handbrake with the rear prop off! :)

If not the UJ then check the play in the diff pinion bearing....this is also best done with the rear prop off.

Steve ray:
Like the guys said, UJs would be the first port of call.

IMHO ......... I'd ditch the rubber dougnut first chance you get - swap the rear prop for a rear prop from a 200Tdi and change theoutput flange to a 4-bolt arrangement. Much better, esp on "lifted" motors

lee celtic:
What he said :D
