I picked up a D44 and a HP30. The guy I got them off of didnt know what year they came from or if they were matching years. He just knew they were from an XJ. The width measures out to be an XJ, but the HP30 is non disconnect which is throwing me off. Is there anyway from the tag on the cover that I can tell what years these axles came from?

Thanks for any help Rob

The original d30 on my 92 was a non vacuum unit.

I have:

91 with non-disconnect front
87 with non-disconnect front

both have the 242 transfer case

Not sure how to ID year from any numbers or markings on the diff - why does the year matter?

This LINK should help.

The D44 is probably from 87-89. That was the most common years they were put in, although some places say up to '91 is possible. It shouldn't matter since the parts will be the same.
