OK, I got some new wheel bearing from Contentional Cycles for my 1978 Columbia Imperial. The brakes are sqeueeking front and back, more of a grinding. Anyway, I figured it was the wheel bearings because the pads are great.I have the Owners manual for this bike, gave them this # SU-755-001-084-1. What I got was too small to fit in the hub. I had already taken the old ones out, but messed one up in the process. Now where can I get this Bearing, Here is the number on it 6202RS-Genbearco. Any help would be great.
