I'm chasing a chatter problem on my 9A & pulled the spindle yesterday to clean out the shim slot's .when I did teh rebuild , new felts, & cleanup & paint I did the outer thrust bearing upgrade . I'm wondering if the inner thrust bearing could be out of spec , I didn't replaced it when I did the rebuild , could it be adding anything to my chatter problem ? have folks been replacing the inner thrust bearing ? if so with a like ball bearing , or upgrading to a needle bearing of sorts ?
