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..

Abs.

is that a guess or is that what it is? are the marks on the splines anything to worry about

It's part of the speed sensor for the ABS. I honestly don't know if the damage on the teeth will hurt anything.

Overthink 03-06-2012 08:03 PM

Thanks, I don't remember ever seeing one before....

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.

It's an ABS tone ring. No guessing involved.

Thanks for everyone's replies..

The claim that tone rings were (ever) included on "all TJs" is factually incorrect.

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.

Re-read what I said. I said Jeep "started" including them which doesn't mean they were always included. They started shipping axle shafts with tone rings within a couple years after the TJ was intro'd regardless of whether the TJ had ABS or not.

Thank you. My '03 didn't have tone rings either. For that matter, ABS wasn't even an option.

Pick any start date you like. You will still be wrong. Unless you mean they "started and stopped" numerous times. Unless I am mistaken, you are claiming that, after some date, 100% of TJs left the assembly line with tone rings. Ain't so.

The tone rings were never on the D44 shafts at all, if you had a D44, you didn't even have the option of ABS on the TJs.

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.

Bone 03-08-2012 08:46 AM

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.
