MJohnny Posted August 31, 2007 Share Posted August 31, 2007 What is the original diff on a 90 ELIMINATOR 2x4 soon 4x4 Link to comment Share on other sites More sharing options...
DirtyComanche Posted August 31, 2007 Share Posted August 31, 2007 D35 standard, D44 avaliable. Link to comment Share on other sites More sharing options...
rockhardzj Posted August 31, 2007 Share Posted August 31, 2007 I'd put 99 dollars and 99 cents down on it being a Dana 35. It's all too common... Get a pic of the differential cover though, and someone will reply with the definitive answer in under 30 seconds. Link to comment Share on other sites More sharing options...
HOrnbrod Posted August 31, 2007 Share Posted August 31, 2007 Stealing Pete's pics post, you have one of the two below. Most likely the D35. Link to comment Share on other sites More sharing options...
carnuck Posted September 4, 2007 Share Posted September 4, 2007 If it's perfectly round and looks like it could hide a basketball, it's an uncommon Model 20. (I still want one for my '87) BTW, the Dana 35 is also known as Model 15 in AMC circles. The difference is M15 came with 2 piece axle shafts like the CJ Model 20s.

CWLONGSHOT Posted September 4, 2007 Share Posted September 4, 2007 Being a 1990, and 2WD, I am also betting on D35 as well. It could have either the steel hex plug OR the rubber fill plug. CW Link to comment Share on other sites More sharing options...

Rob S Posted September 5, 2007 Share Posted September 5, 2007 Let me save you the trouble. Its a dana 35. Unless it has the tow package and some special order, its a Dana 35. Just like 99% of these trucks. Link to comment Share on other sites More sharing options...
Duner Posted September 5, 2007 Share Posted September 5, 2007 If your asking this question then we can be 99.99% sure you have a Dana model 35 axle. We know this because if it had a D44 axle your buddy would have talked you out if already. All kidding aside you can find the D44's under cherokees made between 87-90 with towing packages based on what I have seen in the salvage yards around here most of towing packages have the 44. just walk behind the trucks and look for the receiver hitch then look for the slanted diff cover with the large drain plug.

MJohnny Posted September 5, 2007 Author Share Posted September 5, 2007 Thanks for the info so will an XJ rear axle bolt on the MJ Link to comment Share on other sites More sharing options...
FxRacing282 Posted September 5, 2007 Share Posted September 5, 2007 no the perches are spaced differently. plus if they were you would get 4.5-5.5 inches of rear lift. you could cut off the XJ perches and weld on new ones though :smart: Link to comment Share on other sites More sharing options...
CWLONGSHOT Posted September 6, 2007 Share Posted September 6, 2007 Being a 1990, and 2WD, I am also betting on D35 as well. It could have either the steel hex plug OR the rubber fill plug. CW likewise, it could be c clip or non. Correct, but I'll bet its a "C" Clip D35. 1989/90 was the break for the non "C" Clip so it could be either, but most 90's got the NEW "C" Clip axle.

akamcbird Posted September 6, 2007 Share Posted September 6, 2007 only one place i know of...but this will cause some debate, best to search rocky road http://www.rocky-road.com/xjsus.html oh and my '90 eliminator has a 44 and no tow package (check sig) Link to comment Share on other sites More sharing options...
Tracker Posted September 6, 2007 Share Posted September 6, 2007 only one place i know of...but this will cause some debate, best to search rocky road No debate from me. If I lift another MJ I'll buy another kit from them. It works. The kit doesn't have control arms so you chose your own course there. Also it is designed for a D35 but it will work on a 44 with some grinding. Link to comment Share on other sites More sharing options...

ComancheKid45 Posted December 19, 2007 Share Posted December 19, 2007 So is it likely the Factory axle under my 88 is a Dana 35??? I'm looking at getting a new cover b/c the fill/inspection plug in mine is seized and its an excuse 2 upgrade Link to comment Share on other sites More sharing options...
500 MJ Posted December 20, 2007 Share Posted December 20, 2007 uncommon Model 20. (I still want one for my '87) I know where one is... A friend of mine's younger brother has one in his '86 MJ. Problem is that its a LWB and 2.8L. Both attributes that I would love to stay away from. He had if for sale a few years ago, don't know if it still is for sale or not. Truck was in nice shape too, no rust when I saw it last... Link to comment Share on other sites More sharing options...
Eagle Posted December 20, 2007 Share Posted December 20, 2007 So is it likely the Factory axle under my 88 is a Dana 35??? It is likely a Dana 35, but it is possible that it's a Dana 44. They don't look at all alike. Look at the pictures posted in this thread, then go look at your differential. If the cover is oval, it's a D35. If the cover is trapezoidal, it's a D44.
