Dana 44 questions seem to be the forte lately.....I just finished putting in a D44 into the rear of my XJ. It had factory 4.10's in it, so I didn't touch anything in the case, except to clean it out and fill it up. Nothing seemed to be out of place, but now I'm done and I've got a bit of a groaning noise on acceleration that changes in tone when I'm on and off the gas.
I put the XJ up on jackstands and crawled under it to place the noise and it seems to be coming from the rear diff. So I came back inside, sat down at my CPU and did some searching. From what I read it sounds like this is probably my pinion bearing, but I could be wrong.
Here's my questions: what happens if I don't replace this ASAP? There's nearly as much labor involved in replacing the pinion bearing as in replacing a set of gears right? Am I probably best off to get a full rebuild kit and do everything in the case at one time? I haven't much experience inside a differential, except to replace a set of spider gears in a D35, but I've done a million other things to my Jeep, should I even bother touching this myself? Thanks in advance-
