i have a gm 7.5 rear differential in my 1967 firebird and it has 2.73 gears and was wondering should i change the gears to better ones or change my whole rear differential to a 8.2 or 8.5 differential? thank you
Got to disagree with this. The "axle saver" bearings have caused nothing but headaches with me. I installed them on an El Camino of mine, and on a few customer's cars and trucks and had to go back and replace and repair almost all of them. Once you get them in they are very hard to get back out, and about 90% of them leak oil onto your brakes. If the axles are worn then fix it the right way with a new set of axles and the correct bearings.The only thing I will say, is get the newer type wheel bearing that move the bearing location on the old axels when you redo it. Normally the location where those bearing sit on the axel have years of wear.
