Replacing ABS sensor

[superman04]

How do I go about replacing my front passenger abs sensor? The technician who scanned the abs computer told me the procedure was different and more expensive because the truck is a 4x4 as apposed to the 2wd models. I was hoping I could replace this myself rather than spending the $400 to have a shop do it.

If you mean the ABS Sensor that goes into the hub, You will need to pull the rotor off to get to the sensor. Comes off pretty easy, just have to pull off all the brake stuff, caliper, rotor, and the shoe that the pads sit into. If the sensor is the original you might want to spray it a couple days ahead of time to easy in the removal. It takes an allen wrench to remove the bolt.

No, the only things down that way are the brake line, the ABS Sensor, and a vacuum line if you have the auto hubs.

the strangest thing happened last night. i was driving around in 4wd in the snow and suddenly the ABS light goes off and the ABS starts working again. very strange. and when i got into the truck and drove it to work today, the light was still off and the abs system still worked. am i lucky or is this a sign that it needs some attention still? lol

I would say your sensor was giving a misreading. When you used your 4wheel drive maybe when the hubs locked in it corrected the sensors. I would keep driving it if the light stays off then no worries if it comes back on then I would deal with the replacement of the sensor. Just remember that your brakes will work when your abs light is on.

I believe you have to get the sensor wire thing at the Dealership. Don't know about a price though.

yeah i couldnt find any at the local parts stores, but i found one sensor on ebay and it was over $100, lol. the dealership said they would charge $400 to replace the abs sensor. they said the cost is higher on this truck because it is 4wd and not 2wd.

The abs sensors just fits into the hub assembly and are not hard to change. I know for $400.00 you could rebuild a small block chevy and really improve the ride you were working on HA!!! How things change. I have two used abs sensor as I replaced my hub bearings a few months ago. Just remove the wheel and all brake parts and there it is. Just two bolts and unplug the harness and your ready to go back together. If the dealer had to change the air in your tires it might be a $1,000.00 HA!!!! Good luck as we all know it's only money.
