I have a hp44 front axle that I narrowed to accept Rubicon d44 inners. I've got the GM small bearing spindles and GM stub shafts. Here is the problem. The short side goes together and spins easily. I put the long side together and it will bind up for about 1/4 of the axle rotation. So it moves freely for 3/4 of the rotation of the axle. I can still force it thru the bind by forcing the short side to not turn and rotationg the pinion yoke by hand. It ain't easy, but I can get thru it by hand at the yoke, but not at the stub shaft end. If I loosen the 6 spindle nuts it will rotate freely thru the complete axle rotation. All the parts (i.e. stub shafts, spindles, bearings etc.) are new, so they "should" be good. I would think that if I had a bent stub shaft or the inner "C" was not re-installed correctly it would bind all the time instead of just part of the rotation. Any ideas as to what may causing this? Any advise will be appreciated.
