Used TJ shafts should work if they spin straight. Two things I'd watch: the retainer plates differ between TJ and MJ/XJ, so plan on reusing your MJ plates, and check them on the bench before you pay, since a yard shaft can be bent same as yours. If you go new, the Revolution ones ghetdjc320 linked come with the access hole for the backing plate nuts, which is worth the money. New bearings and seals while it's apart either way.

RockAuto's cross-reference is closer to right than the forum lore suggests, at least for the shafts. The XJ/MJ rear D44 and the TJ rear D44 use the same 30-spline shafts, and the aftermarket lists them as the same fitment across XJ, MJ and 97-06 TJ. Two things to watch when ordering: - Left and right are different lengths, about a half inch apart (driver side around 29-1/4 in, passenger around 29-3/4 in on the specs I've seen). Order by side. - Kits usually come with new bearings and seals. Worth taking while it's apart. The "internet says no" part is mostly about the housings, not the shafts. The TJ has four-link bracketry, MJ/XJ are spring-under, but the shaft doesn't care about any of that. And +1 on confirming the bend before buying. Dial indicator on the flange while it spins is the quick check. If you do fit a set, post up how it goes. This question comes up a lot and the threads never get the ending.
