After driving around for a few weeks one of my drums developed some play. I took it apart and noticed the race for the outer bearings had moved inward. It was just about against the inner snap ring inside the hub. The problem is that none of the tech books seem to cover the installation of the bearing races. My buddy said to seat it as far as it will go. Thats is what I did the first time but somehow the race managed to move about 1/4-1/2 inch inward. So how should that outer race be installed exactly??? I am afraid it will just move inward again and cause more problems. Memorial day is fast approaching and I want to get this fixed tomorrow. Please help!
