Q: ABS Sensor location on 1996 Chevrolet Suburban 1500

ABS light comes on intermittently. Can hear the abs taking over when coming to a stop from slow speed. Does not occur all of the time. Research I have done indicates the sensor may be bad or if rust has lifted the sensor up a few thousands of an inch, this may give a false reading to the sensor. I have checked all four wheels and there are no electrical connections going to any wheel. Does anyone know where the abs sensor is located? If I can locate it, I can try cleaning the area and the electrical connector to see if that cures this intermittent problem. Thank you for your help.

your research is correct with the addition that one of the hubs may be bad. that means if there is play in the hub, it can produce the same results.

Thank you for your quick reply. Maybe I am looking in the wrong place, but I cannot find any electrical connections to any of the wheels. I erred in not mentioning that the Suburban is 4 wheel drive. Could the sensor(s) be located at any other place than the wheel hub assby?
no. they are at the wheels. did you jack it up and see if there is any play in any of the wheels??

there should be a harness coming from the hubs that go up the inner fenders.

I will try to double check again today now that the rain has stopped.
I tried to follow the wires from the main control unit just alongside of the master cylinder, but lost track of them. Initially, I did check all around the front wheels, looked for wires leading out to the rotor and disc pad assembly, along the upper and lower a-frame arms, anyplace else that I could see in that area. Could not see any electrical wires or connectors.
May take a day or so, but I will let you know what I find.
Thank you for your help.
I am wondering if this is an early model that has only rear abs. did you check the rear for sensors??

Just got a chance to pull the l.f. wheel. Did find the wire leading to the sensor. Covered in dirt, which is why I missed it the first time. From what I can see, the rotor needs to come off in order to get to the sensor. Since this is 4wd, I don't have the socket big enough to get that assby off. I may just have to defer this job to the dealership.
Back when I used to spin wrenches for a living, you could do a complete tune up with a screwdriver, an adjustable wrench and a pack of matches (tear off the striker flint and use that to set the points). Nowadays, things are just too complicated. Guess I'm showing my age.
I wish to thank you for all of your help.
Thanks again,
