Hi guys. This is my first post.
I have just bought a 2001 AU II XR6 VCT. It goes great, except for a problem with the rear diff.
At really low speeds, about 5-7km/h, there is a clunking, and the left wheel looks to pivot in and out a bit.
No sign of a problem at speed, and it only happens when its warm.
Ive heard its pretty common, but I just want to get a definitive answer on what it is, if its still driveable till I fix it, and what I need to do to fix it.
Its got about 290,xxxkm on it. Like I said, other than the diff its in pretty good nick.
Cheers

your au has the IRS in the back

could be something to with a control arm busing being worn
or maybe a bent axle?
