juan Posted November 20, 2010 Share Posted November 20, 2010 yes you can, only thing you need to do is remove the spring perches from the top of the axel and reweld them to the bottom to fit the mj - also make sure the gears match your front end.

ryno56 Posted November 20, 2010 Share Posted November 20, 2010 yes you can, only thing you need to do is remove the spring perches from the top of the axel and reweld them to the bottom to fit the mj - also make sure the gears match your front end. the spring perches are also spaced narrower (34" I think) so make sure you don't go with the spacing they are at from the xj. Specs for gear ratios are easy to Google if you're not sure which it has. Quote Link to comment Share on other sites More sharing options...
Pete M Posted November 22, 2010 Share Posted November 22, 2010 I believe MJ perches are 42 inches on center. Quote Link to comment Share on other sites More sharing options...
ryno56 Posted November 22, 2010 Share Posted November 22, 2010 I believe MJ perches are 42 inches on center. Right, that's more likely. 34" would be awfully narrow :doh: I knew there was a 4 in there though. Quote Link to comment Share on other sites More sharing options...
mkbruin Posted November 22, 2010 Share Posted November 22, 2010 Don't forget the driveshaft length issues. Quote Link to comment Share on other sites More sharing options...
