fire797 Posted February 3, 2017 Share Posted February 3, 2017 I am in the middle of building a 1989 MJ. I bought two dana 30 steel diff covers. I put the front one on no problem. The back one just one little problem it is not a dana 30 its a dana 44!! Surprise!!! The tag on it says to use limited slip fluid. Does this mean its a trac lok??? Now the bad news there were pieces of metal in the diff. Looks like one of the plates behind the spider gear is broke. I can't get the pin out with out removing the ring gear so looks like the whole thing is coming out for a rebuild... Any advice??? Link to comment Share on other sites More sharing options...
HOrnbrod Posted February 3, 2017 Share Posted February 3, 2017 The 8-digit p/n should be on the tag. What is it? Link to comment Share on other sites More sharing options...
Eagle Posted February 3, 2017 Share Posted February 3, 2017 The MJ never used a Dana 30 for the rear. The standard axle was a Dana 35. Are you sure that's not what you have? Link to comment Share on other sites More sharing options...

Hypoid Posted February 3, 2017 Share Posted February 3, 2017 You have to use a photo hosting site, then copy the URL for the image to the "picture" button. EDIT: DOH! you figured it out. It is always nice to look under an XJ or MJ and see one of these. :) One thing to note is that some D-44s have three ribs like the one pictured, others have a single, thick rib.

Hypoid Posted February 3, 2017 Share Posted February 3, 2017 Now the bad news there were pieces of metal in the diff. Looks like one of the plates behind the spider gear is broke. I can't get the pin out with out removing the ring gear so looks like the whole thing is coming out for a rebuild... Any advice??? The carrier will have to come out. If you like new challenges and have money for the learning curve, you can rebuild it yourself. Otherwise, take the axle (or truck) to a competent shop. BTW, congrats!
