95whitetrash Posted February 26, 2009 Share Posted February 26, 2009 Okay guy's, what vehicle can I get a front axle out of that will bobuying lt up to my 1986 MJ . I am buying this mj and the front axle has been changed to a two wheel drive axle and i want to put it back to four wheel drive. I know i need to make sure the new axle has the same gear ratio but I am stumped as to which axle will fit many thanks in advance. :fool: sorry it's a 1986 XLS with the GM V-6 and a 4 speed standard that is all i know at this time :help: Great site by the way :thumbsup: Link to comment Share on other sites More sharing options...
mvusse Posted February 26, 2009 Share Posted February 26, 2009 Everything on the front of Comanches interchanges with Cherokees. So any Cherokee front axle (but you do need to check the gear ratio). I believe the only front axle used was a Dana 30. Other vehicles may possibly interchange, like YJ or Grand Cherokee? Link to comment Share on other sites More sharing options...
Rockyrider367 Posted February 26, 2009 Share Posted February 26, 2009 A YJ axle should work but you will need to make your axle brakets to have it bolt up as the MJ is a coil sprung front end and the YJ is leaf spring. But other than that it should work. I don't know about a ZJ but they were still dana 30s and coil sprung but I don't know if it will bolt up you may need to change the suspention mounts.

Pete M Posted February 26, 2009 Share Posted February 26, 2009 XJ/MJ are a direct swap. TJ/ZJ are a direct swap, but are low pinion (as are 00+ XJs). YJ would need extensive welding. Also, I think the 2.8L v6 only had 5 speeds with it from the factory. But the 4-speed version of the trans is a direct swap, so it's possible that it was replaced at some point in time.
