My rear axle is threaded and has threads all the way out to the end. When it sits in the aluminum dropouts, the threads make grooves in the aluminum over time and i think they have caused a clunk sound when the axel is not under pressure and is rotating. i think It does this cause the axle threads are skipping back and forth between the grooves it has created. Its not loud but i can feel it when i am off my bike and guiding it to my truck or inside my house.

Anyone else expereience this? I tried filing/smoothing out the aluminum in the drop-outs to see if it would stop but no luck. the axle threads just made new grooves.

this only happens when i am not on the bike (no pressure on the axle) and am guiding it through my house or to my car etc.

Any thoughts.

I have just recently overhauled my rear hub do to a loose freehub lockscrew inside the hub, and i did notice a "minor" warped feeling when screwing in the freehub lock screw back into the cassette.

Again, any thoughts.

Maybe I might need a new rear hub? or rear cassette?

your axle should not be spinning/rotating in the dropout whether under pressure or not and should not be moving laterally. once clamped in the dropouts the axle is secure and should not have any movement. are you sure this is what is happening?

Do not file off the grooves in the dropouts and keep the QR tight. Once the grooves are there it should slow further damage as there is more contact area.

The "clunk" could be a loose bearing adjustment.

But if it really bothers you switch to hubs with cartridge bearings or the 770 series XT hubs.
