How to Disable ABS 98 ZJ?

So a friend helped me change my front axle u-joint last night. Slight complication when getting it to pop out.

We dented the round ridged section the abs uses to track itself apparently, when trying to bend the dent out a piece of it snapped off (Forgive me for not knowing what exactly the part is called I think I have heard it referred to as a tone ring? I am not exactly a mechanical mastermind obviously ).

Now when I start the Jeep every time I hit the brakes for about the first 20 seconds the ABS is kicking in and constantly pulsating when trying to brake. This can make getting out of the driveway without driving straight into oncoming traffic a bit dangerous.

The ABS fails and turns itself off shortly there after, but it still takes a bit for it to do so every time I start the Jeep up.

Long story short, I can't really afford to replace it right now, and Id much rather just disable ABS all together until I can. Is there a simple relay I can pull? I don't care about the light being on, I just would like to not slowly creep into oncoming traffic .

As well as any idea of what part I'll need to buy down the line later to fix it. Do I have to buy the entire axle shaft?

Would the fuse specifically just be for the ABS, or would I end up taking something else out as well? Would it just be listed in my owners manual? Sorry I'm not exactly the sharpest tool in the shed when it comes to these things.

It is just for the ABS. IF you are unsure, go buy a Haynes or Chilton's repair manual at any autoparts store.

Thanks, I am pretty sure I have one actually in the jeep. I'll give that a shot on lunch.

Any idea what I will have to replace to fix the problem overall? I'm sure I can't just buy the part that broke, as I remember it was rather attached to everything else, will I need an entire axle shaft?

Just remove a sensor from the front wheels. Its only 1 bolt then zip tie it up. I think if 1 sensor is bad there is no ABS. But you will have the ABS light on the dash.

Are you talking about the ring on the axle shaft? Someone here did replace that ring (I forgot who). If the shaft is bad you can get a new one with the ABS ring on it for about $60 I think. Not too hard of a job if you can turn wrenches.

Yes I believe that is what I'm talking about. It was on the spindle yoke side of the joint if I remember right. It looks almost like a gear in a way.

Its something like:


Managed to take the entire thing out to do the u-joint, so I figure I could replace it. Hopefully not breaking other things in the process this time.


Edit:Just noticed the thread link, thats pretty much exactly what I did Thanks for the link, I'll think about how I want to tackle it now.

I see that, I'm just going to have to see how much one is new from that company, going to call them in a bit. Or if I'd be better off just checking a junkyard. As soon as a get a few minutes I'm going to give them a call. In the interim while I wait for the part I think I'll try just pulling the fuse.

I appreciate you finding that for me

Edit: Yeah that company sold out their stock of those with no intent to bring them back. He also said even if he had it, he has a $25 minimum and 12.50 shipping.

Apparently this is a rather common problem occurence. I called http://www.dearbornaxle.com/ which is a place by me. I asked him for the ring, he asked me if i broke it when changing my u-joint and chuckled a bit. He said he didn't but if I wanted the entire new axle he has a truck full of them. $100 Shipped

Sorry, I only had one ring, & NYC ZJ has it now, but maybe someone else can help you. It's rather easy to fix once the axle is out.

This place may sell them:

EDIT:I had some free time, so I called the above place, & they no longer sell them. They recommended:

Again, see if you can contact someone here that may have an old axle laying around. '93-98 ZJ (ujoint or CV) are the same... and probably other, too. Mine was a 719-19 54 tooth
