DansGreyMj Posted June 12, 2006 Share Posted June 12, 2006 i heard that gcs have a better d30 and i wanted to swap in a non cad anyways would it bolt straight up or would i have to make any mods Link to comment Share on other sites More sharing options...
mjeff87 Posted June 12, 2006 Share Posted June 12, 2006 AFAIK, they're the same animal....but the ZJ tie rod and drag link are thicker than XJ/MJ. But, they would all be non-disco, and 297x joints in them, unless they are CV shafts Jeff Link to comment Share on other sites More sharing options...
pingpong Posted June 12, 2006 Share Posted June 12, 2006 They are exactly the same. I am not sure about the u-joint thing though. Link to comment Share on other sites More sharing options...
Pete M Posted June 12, 2006 Share Posted June 12, 2006 Are you asking about ZJs or WJs? Link to comment Share on other sites More sharing options...
BRC 88MJ Posted June 12, 2006 Share Posted June 12, 2006 ZJ D30 is a low pinion design. Some (V8 mainly) used CV-joints instead of u-joints in the axleshaft. Otherwise, they are the same. Link to comment Share on other sites More sharing options...
Bounty Hunter Posted June 12, 2006 Share Posted June 12, 2006 ZJ D30 is a high pinion, same as most all but the newest XJ's. Many had CV axleshafts, easily replaceable with the ujoint axleshafts. It'll bolt right in. I've got a similar question, I just picked up a HP D30 non-disco with 4.10 and CV axlshafts, anybody know what it could have been out of? My quess would be something with a 4banger, but I thought no ZJ would have a 4banger. Maybe a 2.5L XJ with the 242? Link to comment Share on other sites More sharing options...
mjeff87 Posted June 12, 2006 Share Posted June 12, 2006 prolly an 84-85 XJ with the 228/229 TC. Link to comment Share on other sites More sharing options...
pingpong Posted June 12, 2006 Share Posted June 12, 2006 More then likely It could have been any XJ with a 242 t-case or as Jeff said an early model XJ. One way to tell is the early model xj's SOME used regular 6 point bolts :eek: Link to comment Share on other sites More sharing options...
Bounty Hunter Posted June 12, 2006 Share Posted June 12, 2006 One way to tell is the early model xj's SOME used regular 6 point bolts :eek: On what? The bolts on his D30 look like all late-model D30's I've seen, but it has the early bolt-on caliper bracket instead of the later 1-piece knuckle/bracket.

pingpong Posted June 12, 2006 Share Posted June 12, 2006 I have seen 2 D30's that appeared to be un altered in the local j-yard with 6 point bolts holding the unit bearing in. These were CV shaft equipped xj's. You are also right about the different style calipers too. Link to comment Share on other sites More sharing options...
minydigger Posted June 12, 2006 Share Posted June 12, 2006 My 94 ZJ limited has a low pinion w/ cv axles. Link to comment Share on other sites More sharing options...
whowey Posted June 13, 2006 Share Posted June 13, 2006 More then likely It could have been any XJ with a 242 t-case No, my 88 with the 242 has regular old joints. Gotta go with Jeff here. Early XJ, with the full time case. BTW, my ZJ with the 249(full-time) has CV joints on the front axle. Link to comment Share on other sites More sharing options...
rejeep Posted June 13, 2006 Share Posted June 13, 2006 The ZJ's & TJ's are LP.. XJ & YJ are HP Link to comment Share on other sites More sharing options...
Bounty Hunter Posted June 13, 2006 Share Posted June 13, 2006 Ahh, never knew that about ZJ's, always learning something new. Link to comment Share on other sites More sharing options...
