Also if you have ABS in your Cherokee, there is a 99% chance that you have a rear d35 so you get the worst of both worlds...

onroad: ABS is nice in the tow rig... the end.
X2 I deleted my ABS when I swapped to the 8.25

I pulled all 3 fuses for the ABS and the light still stayed on. 1 fuse says it's for the light, another says it's for the solenoid and the last says it's for the ABS motor.
Anyone else have any other ideas to get the light to go out? I have been having problems with my ABS feeling like it's activating all the time when coming to a stop.

Thanks again for all the help. Keep it coming

Find a nice empty parking lot on a rainy day, get going 20 MPH , and stand on the brakes. If the brake petal pulses and the wheels continue to roll (check spedo) as you stop, you have ABS. If your wheels lock up, then you do not have a working ABS system.

For Mickdime:

I worked in ABS development for Bosch for 8 years as a test engineer. Some of the advanced features such as trailer sway control, hill descent control, electronic stability, and roll stability control can be very usefull. Basic ABS is good if you have to stop quickly with one side of your vehicle on a slicker surface than the other.

That being said, I have 5 vehicles and none have ABS.

Try jamming the brakes at 60 with one set of wheels on wet slick tiles (or ice) and the other on dry pavement. You get a nice panoramic view that repats every 4 seconds till you come to a stop. We tried it with and without ABS at our Flat Rock, MI testing facility:

Check out the 25MB video. The ABS events start at 3:20 and 6:20.

Do you have an ABS motor right by your master cylinder?

Man, I'd hate to have your tires. You must have flat spots everywhere.

Or just find a loose gravel surface, it shouldn't even take 20 MPH to lock 'em up.

Yes, lets try doing something you really aren't suppose to do.

I'm not sure where you learned to drive, but I learned very early that you NEVER just jam on the brakes, let alone on unpredictable surfaces at highway speeds. What the hell do you expect to happen?

Maybe the big problem is that most people don't know how to drive, and don't care to learn? How about, you shouldn't be flying down the road at 60mph if there is a chance of slick surfaces or a need to suddenly stop?

I had hoped that you noted the sarcasm in my comment. I do not recommend trying this. This was done at a test facility under controlled conditions (100 ft x 1000 ft test pad with high and low mu split surfaces. "Professional driver. Do not attempt." I was trying to make a point about the benefits of ABS. You can not always control the driving situation you find yourself in on the streets, sometimes it is helpfull to have ABS to assist you through those situations. For off road situations, shut it off if it is possible.

I learned how to drive in central Florida where it rains every afternoon around 3, I leaned to respect slick surfaces since all I had to drive untill I was 19 was motorcycles.

sorry for the hostility, I had so many pains with my ABS, ripping it out was one of the most fun things I did to my XJ

p.s. notop46, I like your RED XJ!

I like yours as well. Very clean! It is great to see that 20+ YO vehicles can look so good with a little TLC.

For those out there watching and contributing to this thread who have removed their ABS:
When you removed the ABS, did you have to install an adjustable proportioning valve to keep the rear wheel pressure down to avoid locking up?

For those interested in learning more on the subject of ABS:
I do not know anything about the ABS systems used on Jeeps (manufacturer(s), set-up, ...). The ABS systems for trucks and SUVs thru early 00's were very limited. They often treated the rear wheels as one entity and controlled the fluid pressure to the rear axle to prevent both wheels from locking. With the addition of traction control systems and electronic stability control, independant control of the rear wheel pressures was required and ABS control on the rear axle improved (somewhat).
