I have had the truck a year and a half, no probelms till now when I bought the truck I installed a bullydog 4 bank 6 pos. chip, gauge package for the A pillar and K&N cool air intake. Wondered if anyone had any ideas what might be going on. Thanks for any help!
ABS Sensor on your rear differential is BAD. This is a SIMPLE and EASY fix. Goto your nearest autozone (cheapest price on this item) and buy the sensor. It will cost you a total whoping $15.00 (tax included). NOW. go to the rear differential and on top you will see it with a wire going to it. Clean off the hole that the old sensor goes in and grease up the O-rings on the new sensor. I believe its a 3/4 American Wrench. Ford has yet to move to Metric bolts on their rear diffs lol. cheap bastardos
I have pictures and better instructions and part numbers, but they are all in my truck bc i am working on the front right sensor.
