A couple of weeks ago I noticed a knocking/rumbling from what seems to be the diff, it is right at the back. I looked at the Viscous and it seems ok. I noticed the front diff mount was failing, so I replaced all three. Seemed to fix it. However a day or two later it started to come back, now it is a week later, it is not anywhere as bad as it was prior to replacing the mounts, but still doing it when I am turning into parking spaces or into a driveway at low speed. It seems like a bearing perhaps, but I am not sure. Before the mounts were replaced it was doing it whenever I turned at any speed or when going straight at faster speeds and taking foot of pedal, only to stop when foot put back on the pedal, but again not since mounts replaced. Seems like something has worn and is knocking about, but now that the diff is held more firmly in place with new mounts, it isn't as bad as before...yet that is, give it a few weeks and it could be!
Any ideas???[/b]
