Depening on the year, I believe the rear uses the abs sensor on top of the pumpkin, so you cant clean that. The front sensors should be on the hubs/ steering knuckle.

Well, Im not to sure where it would be since my jeep doesnt have abs. On our grand it looks like this.

This is on a SFA though. It should have some teeth like that and a sensor really close to them. Sometimes dirt gets inbetween the teeth and the sensor.

There is nothing to clean on the rear pumpkin, check to make sure the wires going into the top of it are in good shape though.

It is just under the rotor on the top of the knuckle. Just follow the black line the goes over the bumpstop down to the knuckle. I had a replace mine a few months ago, the ABS line got crushed between the spring and the bumpstop. If you need to replace it, they are about $35. I'll warn you, mine broke while taking it out. The o-ring seized in the knuckle and broke the mounting tab right off. I was suprised to see how clean it was when I finally got the sensor out.

Thats crazy, the sensor goes into the knuckle. Kinda cool, can it even get dirty?

even though my bearing was fried when i tookthe sensor out it was very clean and i have had that thing submerged in water and mud not even wet in there except like what grease and stuff that would be in there for the bearing.
