Well i finally managed to get my z on a 2 poster yesterday and it was quite enlightening.

 

I've got fancy shocks :hyper: dunno what brand (either Tein or Cusco i think) but they're height adjustable - via a large nut at the bottom of the spring that threads up the shock from the bottom.

 

They guy who owns the workshop told me that this kind of set-up will nock and there aint nothing I can do to cure it (other than replace it of course).

 

Does that make sense to anyone?

 

The nocking sounds like it's coming from the top of the shocks. I've taken all the trim out of the boot and it doesn't seem to be anything "topside".

...long shot, but a million years ago when I first bough a Z (import) it came in all clean and shiney but all the shocks knocked. To cure it I treated them to a little silicone spray both on the chrome shaft that moves up and down and around the contact with the body work, and around the rubber connection at the bottom. I also used it in the engine bay around the top of the shocks. And guess what - all of the knocking and creaking and groaning went away - so I treated all other bushes etc with same spray. And since then I have done it to all (I'm on my second) my Z's - treat it as a summer maintanance task.

 

...worth a try - only about £4.

 

Good luck

Check the anti roll bars. See if the rubber is worn or the clamps are broken. Mine was knocking and it turned out to be the clamps. Ive got the same setup and ive broke 3 sets of clamps.
