Been fighting this dang thing all day.
Pulling 3.08 gears, going in w/ used 3.73's. I bought a FRPP install kit expecting to get timken bearings, and got koyos. Looked at the pinion and in paint marker is a -0 along with some other jibberish I can't make out... so I throw .030 of shim on it, and put the koyo bearing on it. I slip on the NEW crush sleeve and go to pull it up and the pinion practically locks up before I can get even .005 crush on the new crush sleeve. I've pulled it out a dozen times, inspected it, can't find anything wrong..... SO, I whacked on the old crush sleeve and opened it up .020+ or - .005 and SAME THING, I get no crush this time and the pinion locks up.
All I can figure is the Timken races I left in the housing aren't ground on the same angle as the koyos and they are binding when I load them. Before I s-can them has anyone used these bearings in timken races? I know it's not advisable, but I don't wanna attempt pulling and replacing races with this rear end in the car...
I'm tired.
