Well after readin' some of the recent threads on the ACS freewheels and the dreaded clunk, of which I had been sufferin'. I attempted to oil mine thru the unsealed gap on the front plate which sorta helped but I wasn't satisfied. I removed the front plate but was reluctant to add grease it just didn't seem like it would help to add grease on just the bearings and I wasn't gonna open it any futher. So I removed the entire freewheel and low and behold there lay 4 shall we say grease ports? I then took a light weight lithium grease filled syringe and started shooting till it oozed out the other side. The result, so far, a quiet smooth claw...
