88manche4x4 Posted August 30, 2008 Share Posted August 30, 2008 I need someone with a longbed MJ with a 4.0L/aw4/242 to measure their rear driveshaft from u-joint to u-joint. I want to get a driveshaft made while I'm doing the 2wd to 4wd conversion so I can drive it right away. Link to comment Share on other sites More sharing options...
redneck23ms Posted August 30, 2008 Share Posted August 30, 2008 i have an 87 longbed 4.0 aw4 231 and the driveshaft is roughly 49.5" fromt center -center Link to comment Share on other sites More sharing options...
Motion Offroad Posted August 30, 2008 Share Posted August 30, 2008 Being that the NP242 never came in a MJ your probably not going to get many answers. Driveshaft length will also vary greatly on the amount of lift your running and if that lift is achieved via SOA or SUA. It's recommended to lift your Jeep (if you are), get everything in, than measure what you need. I can almost guarantee you that having a driveshaft made prior to doing all this will just cause you a headache and more money down the road. Just wait and do it after you've got it all buttoned up. Just our penny and a half worth... Link to comment Share on other sites More sharing options...
ORCA Posted August 30, 2008 Share Posted August 30, 2008 I second motion's response. It would be a costly mistake to have a driveshaft made before the work is all done and find out later that it is the wrong size. It may end up being the same size, but it's always better to be safe than sorry. Besides any competent driveline shop can produce a shaft for you within a day or two.
