ZJ D30 is low pinion. I wouldn't use it.sbxoxj said:how strong are V8 zj axles?
explorer said:ZJ v8's after 93 used Alum. hsg. Dana 44 or "super 44". These use a gearset that is common w/ Vipers and Vettes. Has a slightly larger ring gear than a standard 44, slightly larger pinion shaft also. Hence the "super 44". As far as disadvantages, it uses a crush sleeve rather than shims to set preload on the pinion. Alum. hsg. MIGHT not hold up as well to banging rocks, but could be skidplated to fix that. Gear ratio and diff. options are limited. Gears are available in 4.1 and 4.56 aftermarket I believe, but are more $$ than a standard 44. But, if you aren't looking for more gear than that and can live w/ oem Traclok, nothing wrong with them if they're properly setup. Barely heavier than a dana 35. Fronts are low pinion, but otherwise similar to XJ with most (all?) v8's having c/v shafts instead of u-joint shafts. Oh yeah, for those who want to get rid of their "junk" c/v shafts, I'll take em. They hold up as well or better than u-joint shafts on my TJ w/ Lockright and 32" swampers.

the alum44s will crush if you as much as jack off the pig ive seen it happen they dont hold up
93 and later is the 2nd-5th year of ZJs, not all of them came with a44s even the v8s, i know pletny of 5.2s and some 5.9s with 35s
i dont really know jack about XJs, but i know a shitton about ZJs
not boasting or anything, but what i know i know, and am happy to pass on :thumbsup:

in addition to the D44 problems mentioned above. these things need to be overhauled alot b/c the aluminum and steel expand at differnt rates with heat and the bearing wear out faster than if it was an iron D44
