strange clicking noise from the back of 4200

[Zep]

I think there were a couple of companies that said they could rebuild the 4200 shocks. One was in ireland i think but theybhad to see the shock first as not all were repairable.

I cant remember which companies did offer the service. Will post it up if i remember.

Its PPCP - its in this thread. I doubt they do surgery on the valves though, replace seals and machine the bodies I believe.
