<div dir="auto">If the clunk goes away when warm, maybe as a stop gap use a different oil. I have a Stag. Play in UJs cause clunks but since you mentioned it goes away when warm, likely to be diff. The Stag uses a similar setup. Rebuilding a diff in USA is about $1500.

<p class="MsoNormal">I chased after a "rear end" clunk for years. Decided it was in the differential, and decided to replace it with a Nissan R200 limited slip after replacing u-joints and checking mounts many times. When I was installing the differential
and new, shortened drive shaft I discovered one of the transmission mount bolts had gone missing.<u></u><u></u></p>

<p class="MsoNormal">Twenty years of rear end clunk when I put it in reverse with cold engine and I'm tired of it. But as soon as the engine warms up it disappears and i dismiss it. Do I bite the bullet
and get it checked out? I'm sure my mechanic will say get it fixed. And how much do you think a repaired rear end will cost me? <u></u><u></u></p>
