CWLONGSHOT Posted August 13, 2007 Share Posted August 13, 2007 Twisty, you forgot a couple.....All MJ's where Hi pinion and all ZJ' and WJ's are LO pinion. :D As I don't believe MJ's ever got the 242 T case, All where a Hi pinion Vac disco for the year 1989... (I know MJ's stopped production in 1992) To expound a bit, all XJ/MJ with the 231 T case made before 1995/96 got the vac disco front axle. If it had the 242 T case it got a solid axle.. but even then, it got the small joints until 1995/6. CW Link to comment Share on other sites More sharing options...
