I bought two front bearing kits today, but before I went to install them, I thought I should try to tighten the outer bearing first.

I loosened the clamp, pulled out the outer bearing, cleaned it, repacked it, reinstalled. Bearing and race looked fine. I finger tightened the clamp then tightened it to about 100 degrees. With the rim on, it will do two-three complete rotations. Lateral play is gone now, but I am still getting an intermittant low drone "humm".

Whats your thoughts?
