Hello, I recently rebuilt my 2003 Sherman slider to change the oil and re-grease the innards. But when I reassembled it when I compress the fork it makes a resonating rubbery 'wwwwhhhaaaaaaaa' noise! So I pulled it apart again everything was in place (to the absolute best of my knowledge) I pulled the spring and compressed the fork and there was no noise coming from any of the damper or bushing. So I popped the spring back in and with the lowers still removed I pushed on the spring side and the noise was still there. The fork also seems a bit stiffer? Im guessing its the spring binding against the inner stanchion. Is there some special trick to fix this? I DID re-greased the spring
