Jeep TJ Rear Identification

Jul 12, 2003 16 Replies

I have done some searches, but haven't found any way to identify the rear differential on my 1998 Jeep TJ. I am assuming it is a 30 front, 35 rear, but I was just wondering what identifying marks should I look for? How can I tell that I have the 35? I am asking this question due to the fact that I bought this jeep used, and it has a bunch of other upgrades (from factory). What identifying marks would the d44 have?

What? Bill hasn't posted a link yet?

He must be busy.

I bet he has ABS brakes, which would get him the 35.

Nope, no abs according to the breakdown. Strange eh?

You don't need to call anybody.

Look at the diff. If it looks like an apple (a Washington Delicious apple to be precise), then you have a D44. If it looks like anything else and you have a D35C, or a TJ that has been modified, in which case the dealer won't be much help.

Lots of pictures of Dana axles here...

If it looks like an apple on its side, it is a D44, otherwise it is a D35C. Another trait of the D35C is the fill hole has a rubber stopper in it, the D44 gets a screw-in plug.

That must make mine real, since my front axle does...
