I recently replaced the control arms on my daughter's 2001 S10. Part of the process was replacing the ABS sensors. I found some cheap from 1AAuto, $42 for the pair. The driver side is fine, but the passenger side chewed up the first one and when I went to replace it, I noticed that if I put it in flush to hub, it was hitting the sensor teeth in the hub. My question is:

1. Is there a shim that goes between the sensor and the hub?

I realize that the distance is critical between the sensor and the sensing gear, ie too far or too close it won't read accurately.

I backed the second one out far enough so it wasn't hitting, but my abs code reader is saying the the sensor is bad and the sensor history is bad too.

Thank you in advance for any help!

ps I have used this forum faithfully ever since we got her truck back in 2013

 

most the time at work we just replace the entire front bearing assembly as its not that much more then just buying the sensors and that way theres no issues like youre having.

i have seen spacers that fit specifically over the abs sensors where they meet the abs sensors but have no idea where you would even find them at

 

Thanks abig84, I'll install a new hub assembly and see if that fixes the problem. One thing that I have noticed looking through this forum is that ABS sensor problems are more common on the right front. I wonder if it has to do with the how the wiring is routed.

 

There are in fact shims that space the sensor from the hub. It's most common to find them on the aftermarket hub assemblies where the sensor and the hub were made in different factories and then brought together to create the assembly, and tolerances are not always perfect... I stumbled across a few in the junk yard looking for an sensor to replace the rubbed-through one on my passenger front wheel.... Believe it or not, I ended up using a sensor from a 02ish Silverado. The sensor head is the same and bolts right up to the hub, and the plug at the body is the same, the wire is just about 10" longer and the clamps on it were in different spots. The extra length was nice because it gave me a little more routing flexibility, which is all fine and dandy as long as you don't leave the extra wire to dangle around... And the wrong brackets are just bent around the wire; I just unbent the clamps and removed them from the wires, installed the wire, then reinstalled the clamps on the wire in the spots I needed them to hold the wire out of the way. Some well placed zip ties helped too
