clanking noise when lift clutch up to quick

I have a clanking noise that sounds like 2 pieces of metal hitting together when driving casually during changing gears caused when lifting the clutch up slightly too fast. When diving flatout that noise is not present. The noise sounds like its coming from where the front seats are located.



At first I thought it was the transmission mount as it was starting to come apart, that has been replaced and the noise is still there.


I also have Whiteline rear outrigger bushes fitted (the O-ring sandwich type), Im not sure if this is the cause/side effect of it as the noise as been there since it was fitted.


Any thoughts, thanks in advance.

Do you run the rear diff locking kit at all?

No I don't, just the whiteline bushes for the rear outrigger.

Re: clanking noise when lift clutch up to quick

its a cheap way to rule out anything at the rear end,
If you hadnt said you had the outrigger bushes Id have said it was them, pretty common.

Are you saying try fitting the rear diff locking kit bolts?

Re: clanking noise when lift clutch up to quick

I went to see Andy Kindon at AS Motors in Chester le Street about the knocking noise. He said it is slight play in the diff and its nothing to worry about. He even checked the rear diff bushings and he told me that its spot on center nothing wrong with it.

I asked about aftermarket parts that can be fitted to the diff, he said as the knocking is not when it under heavy load (hard acceleration) it will make no difference.
