Doesn't matter Ross, that was the old diff. The people who bought it off me insisted on driving it home with an un-inspected rear end issue despite my advice.
In the process it destroyed the whole diff, centre, both axles, wheel bearings, dropped a wheel and whatever else. 8/
I wouldn't be surprised if the work done wasn't done properly, therefore causing this.
Does it still have a KE30 type diff Will?
Cheers, Ben.
