I had a garage in Co. back when the state required safety inspections were 50 cents and the inspection required pulling a wheel to check the brakes. I always pulled a front wheel cuz the front brakes were usually worse. Along with all the other brake jobs, front end work etc., I did more bearing handling than the average bear. Running into noisy or pitted brgs that HAD to be replaced was a very low percentage. I even reused the brgs/races in the biggest POS, entry level 5er I ever owned that had cheapo Chech brgs/races that were very dull and blotchy gray. They were smooth and no signs of over heating or pitting and they did fine with repacking. Not that there's anything wrong with replacing old stuff if you feel more comfortable! Craig
