X300 Rear Bumper Brackets that corrode

Replacing the Rear Bumper Brackets (also affects the XJ40)
The rear bumper mounts are often the cause of a thumping sound at the rear of the car and is frequently accompanied with a lop-sided bumper.
The mounts are made out of a tough plastic with a metal adjusting collets located at the rear end.
The mounts then fit directly to the body shell via four bolts (two of which hold the rear silencer brackets in position). There is also a thin rubber gasket - which must be replaced.
A long central bolt with a drop spacer fits through the rear bumper outer casing and cross member up through the adjusters and into captive nuts in the cross member itself.
To do this job you will require the tools and parts listed at the end of this article.
Failure is often found to look like the pictures below.
