So I'm putting on new wheel studs on my '98 and notice this gear that I dont remember having on my '97. What is it and what does it do. Has some plier or wear marks on the end of some of the splines..

It's called a Tone Ring which is what a Jeep's ABS system uses to know when a brake is locked up or not. Jeep started including them with all TJs regardless of if they had ABS or not so if your TJ has ABS, don't screw with it. If your TJ doesn't have ABS, it can be removed if you like.

And that is factually correct. Some do, and some don't; I had them on my '97 and the D30 from a '98 that I swapped in did not have them. It took me a while to make that stupid ABS light go away.

That was true up until 04 IIRC, maybe 05, but I do know we've been caught by that assumption a few times and there are indeed Dana 44 rear axles with ABS in some years of the TJ.

Similar to a body shop buddy calling me and asking when Jeep put 4:56 gears in, I had to do some research before I learned that the 2.4 auto had them.

I don't think Jerry was trying to say that they ALL had them, he was just saying that they were arbitrarily shipped regardless of ABS. All ABS equipped TJs had them and SOME non-ABS did as well. My ABS '97 had them, of course, friends with a '99 and a '01 did not, and another friend with a non ABS '99 did.
