Reply to "1/2 shaft rebuild"

FWIW- to rebuild halfshafts by Jack's method:
First, take the halfshafts apart at the splined joint and check the sliding fit. I've seen several in which the splines were twisted and sticky- probably from shock loads either drag-racing or not getting out of the throttle when airborne. There is no fix for this and since halfshaft halves wear together, you probably aren't lucky enough to find a half of a junk halfshaft and have it fit together with another piece. If they're worn out, there's no sense continuing the rebuild; find another halfshaft.
There's a felt ring in the threaded connector holding the sliding splines together that could do with a spot of grease, as well as the spline zerk itself. When reassembling, be SURE to have the u-joint crosses index parallel or the car will shake like a wet dog at speed if you're off even one spline.
Then, replace the u-joints with your press, being sure they are greased beforehand if there are no zerks. The protective grease they're shipped with is not sufficient to drive on. If you don't need a press to push the old ones loose, the u-joint holder is probably worn out- also not repairable; see earlier post.
Finally, by using reduced-hex jet-nuts or 12-point nuts (available from Summit & others) on all 12 bolts, and arranging the bolts such that all 12 point toward the middle of the halfshafts, you can actually get a torque wrench on halfshaft nuts rather than guessing at the tightness with open-end wrenches like we always did before. If even one of the 12 bolts & nuts are even slightly loose, the car may shudder on hard acceleration. I do not use lock-washers on halfshaft bolts & nuts; I use small diameter hardened aircraft washers which do not crack.
