I am going to be replacing my rear wheel bearings soon as my right one is bad. Its been bad for a short time and im thinking that the axle is gonna have a wear mark so i want to get the problem solver bearing for that side. The problem is that i have the 7.625 ring gear and i can only find it for the 8.5 ring gear. I was wondering if they make one for the 7.625 or if the axle shafts are the same diameter? My blazer is a 97 with the GU6 3.42 ratio
