I replaced the rear ABS sensor on the rear diff over the weekend. Thanks to everyone who posted instructions on this site. Took no time (other than washing off the grease from the spare tire) and took care of the problem for $21.00. What else does this sensor affect if anyting? I have been complaining that I felt like the truck has been dragging *** and not coasting for a while. I feel like I the entire drive train is now spinning free and trans is shifting easier. Am I imagining things?
