I have a set of DA high flange hubs and the front hub seems to get loose a little bit. I have tightened them up correctly several times. I even did a full overhaul and everything looked to be alright. I had my LBS check them out and they said everything looks fine on them and they look like they're in great condition. So after right tightening the lock nuts, I decided to put teflon tape over the threads to help keep the locknuts from loosening (if that was the case). This did the trick for like 2 days and now the front hub has loosened up just a little. Do you guys think my locknuts are in bad shape or what? Again, the LBS and myself both agree that the cones look fine, the inside of the hub looks fine, all the bearings are good. The only other thing I can think of is that the locknuts may have been worn down some on the threads and loosen up easily. If this is the case, how do I go about getting new locknuts or even a new axle if needed? Or is there a way to just send the hub off the DA and get it fixed? I bought these hubs from a guy on BF and I am really pleased with how good they look and feel, if I could just get this problem fixed. Let me know what you think for a solution. Thanks!
