I got an axle out of an 85 and averything seems to be in pretty good shape. Im going to rebuild the whole axle anyway, but the pinion is loose. I can move the pinion in and out about 1/4inch. I can imagine why. The way I see it is the pinion is moving back and forth on the ring gear. I havent pulled the third out to see whats going on yet. Is there a bearing that is shot? I have never set up a pinion before. I have put a locker in and set the back lash but thats it. Any info would be great. Thanks Stinson
