I recently put a 9" rear in my car, with 4.11s and a trac lock. I had abs reluctor rings pressed on to the axle for the abs. I also had the computer adjusted for the gears and other changes.

The problem is that the car sets off the abs light after about 1-2 miles of driving and it stays on. However when I let the car sit and start it up again.. the light goes off and then after 1-2 miles it sets off again!

Everything is hooked up and should work.. what is the issue?

people have done this swap before and ran abs, I'm sure its something simple, does anyone have any pointers?

Replace the rear ABS harness.

Mine is doing the same thing. My 4-channel ABS worked fine before, but I figured my ABS rings must be different than the stockers to some extent. When you get it figured out let me know.

I have just installed a 9" with 4.30's to be exact...

Is it a 3 channel? I was trying to chase down the same problem with my 9in. My rear ABS harness looked fine so I never replaced it. But after awhile I went to junk yard and got one for free. Turns out the plug that goes into car had connectors pulled out too far and didn't make a good connection. Now ABS works perfectly.

I don't have 4-channel....but do some reading. I have seen threads where they talk about a shim or something to fix 4-channel set ups.

Quickest way to fix it is get it scanned and see why its turning on the light.
