Saloon upper mountings can corrode to the point of destruction. Even tired rear top mounts rarely knock.

Check the metal sleeve / spacer has been replaced on the threaded part of the top of the shock. If they have been off / replaced previously, this is sometimes not replaced as they corrode or are overlooked which results in sideways movement at the top of the shock, and the top rubber mounting being overtightened / squashed and then not doing its job properly.
If this isn't the cause of the knocking, the its likely the shock is knackered.

This part no is for saloon top mountings.
I'm sure VX will give you a price if you ring them quoting this part no.

Assume these are standard shocks and not self levelling? If so have you removed the shocks and checked them? I would imagine that it's more likely that the shocks are shot then the top mount has failed. I'd check them out before you buy anything.

New Boge or Sachs rear shocks usually come complete with original spec top mounting parts. At least they did last time I bought some. Other makes may well include a mounting kit but the components may differ from the originals.

Indeed the crap supplied with the Bilstein shocks only bear a passing resemblance to the originals if you're blind, drunk or both ;D

The individual parts are easily £15-20 a side... Might be some seller profiteering going on...
