I recently put a 6" lift on my 2000 silverado. The brakes worked perfectly before I put the lift on, but afterwards the abs kicked in at low speed. This occured even with the stock tire size on. I have read forums about the sensor collecting rust and causing similar problems on other trucks, so I have cleaned the sensors (3X), I have put dielectric grease in the hub, I have checked the hub and it apears to be OK, but I still have the problem. No one will sell me just the sensor without the hub assembly (even wrecking yards), and I don't want to spend hundreds of dollars just for a wire. I have had the abs fuse out for some time now, but my cruise control does not work when the fuse is out, so I really want to get this problem fixed. I am brand new on this forum, and really apreciate you taking the time to read my problem.

First off, you put a 6 inch lift with stock tires? Ok... I am no mechanic, but have you checked and cleaned both left and right sensors? If you really think this is the problem I have a spare hub with sensor in it. If it removable, I will sell it to you. However, like I said, I won't gaurantee it is the fix.

The speed sensor is 15716191 and should cost around 83.00. That is what my research turned up. I have yet to buy one because after testing both sensors I found the left one way low in output and I had it cleaned. That fixed it...for now.

How did you test your sensor? I have had both sides off numerous times, and cleaned them. I have also cleaned the hubs were the sensors plugs in. The sensor itself is very simple, and I am not sure this is the problem, however it happened spontaniously after I got done installing the lift. Thanks for you help.

I jack the truck up, plugged a multimeter that I got at Radio Shack (a cheap one will do) into the sensor wire plug and spun the tire. 350mv is minimum. I had 125 on the left and 380 I think on the right.
