ABS light coming on and off..

I have a 97 tj with a 4.0 5 speed, I just had to replace the rear (3.07 dana 35). The rear I got was Not ABS, so I swapped my axles and installed my abs sensors, I had checked the distance between the sensor and the "teeth" on the axles. It was reading .035 Make a long story sort jeep runs good and brakes works fine, however the light comes on and off. It usualy takes about 10 min of driving before it comes on and then when I shut the jeep off and restart it the lights out. Anyone have any idea what this could be? Or what I can check? Is there a fuse I can just disconnect? will the brakes still work fine? Thank you

The normal brake system will still work fine with this kind of a problem. I'd have a friend look the sensors over & their alignment over the tone-ring on the axle shaft. Sometimes someone else can spot a problem that the installer keeps overlooking.

Also, could there be any road tar on the sensors? My previous TJ developed an intermittent ABS error light condition that proved to be road tar on one of the front AB sensors. WD-40 and a rag took care of the problem.

I will double check everything There could be a buildup of gunk on the tone ring.

Ok I've attached 2 pix off what I think are abs sensors here. Both pix are from drivers side - 1 after thoroughly cleaning 1 after reinstalling. If you look close the end is mottled/damaged compared to pass side. Could this be? If this is the sensor n I've cleaned both...rear has drums didn't see any sensors there... Should I chg this one? What else could poss turn lite on? Thx so much. -Tim
