Help converting 99 XJ from ABS to NON-ABS
 

Hey there,

I know there are a lot of forum topics on this matter and I have done my research but none of them have really answered my questions.

Here is a little background information:
- I have a 1999 Cherokee XJ with a D30 front and D35 rear and it is equipped with ABS
- I want to convert my rear end to a Chrysler 8.25 (which doesn’t have ABS option)
- I also want to install an Airflow Snorkel (which doesn’t work with ABS)
- As you can see I need to remove my ABS
- No I don’t want to just remove the fuses and relay I need the entire unit removed

My concerns:
- I am basically looking for someone who has actually done this swap on a 97+ XJ
- What parts do I need from a NON-ABS equipped XJ?
- Are my Axles ABS specific or will I be able to keep my D30 up front?
- Do any of the computers in my Jeep need to be replaced with a NON ABS computer?

Any help would be greatly appreciated. As you can see I am new to the Jeep world. I come from the car world so a lot of this is new to me so please bare with me.

Thanks in advance!

Will

1) new axle
2) pull the fuse

If you dont want to just pull the fuse you have to remove the ABS thingy, make new brake lines, and then pull the fuse

Grab the M/C, Brake Booster, Prop. Valve, and hardlines from a non-ABS JY XJ (97+) and swap them into your rig....















and don't forget to pull the ABS fuse.:thumbsup:

Heres a little update. After a lot of research i think i figured it all out.

The Master Cylinder and Brake Booster are identical between ABS and NON-ABS 97-01 Cherokee XJ's. The Prop Valve and Hardlines are what are different. So all you really need to purchase is a new Prop Valve and new hard lines. This i feel is the "right" way to do it, this is my personal opinion.

There is a way to use your existing prop valve and hard lines by bending the existing wiring, buying a t-fitting, some adapters, and makeing a couple double flares. Personally i dont feel this is very full proof unless you are well versed with a double flare tool and are confident in your skills and understanding of your brake system. I was not confident in myself and figured redoing the entire system was the safe and proper way to do it.

At this point i have removed the ABS system and am prepping the remove all the electrical wiring and ABS hard lines. I source a 99 NON ABS prop valve and hard lines so that is sitting in my garage waiting to be installed.

I will update as i get farther along.

any updates? i know its 2020 but with all my down time from the corona virus pandemic im looking to do this same swap.
