Just thinking aloud here:Could be , not sure
Powder metal spray weld build-up and turn to oem dimensions. Remachining splines would need a lot more machining time and talent.Just thinking aloud here:
if it were the bearing surface, there used to be a kit on some bigger gm stuff that had an offset/recessed axle bearing.
i've wondered about having that surface machined/sleeved and put back to oem spec.
does that capability exist?
