Hey Greg , how's trick's
This will sound mad , but as i have replaced the rear diff on my car bare with me.
Is it a deep clunk, clunk, clunk, or just a light click, click,click or winning noise.
You said it happens on acceleration and when stopping , on my experience a diff wouldn't do this
It would only make noise at 1st, on hard acceleration or if there was 3 lads in the back and progressively
get worse the longer you leave it, basically if you where driving softly on your own you wouldn't here it.
At a wild guess it could be the rubber bushing at the end of the drive shaft going into the diff, if this was
gone it would knock on acceleration and braking :dunno:
Very hard to say with out actually hearing it , best get it checked
Niall.
