Goodin72,
I am going to take the truck tomorrow to a shop to scan for codes on the ABS system. I drove it today and the brake pedal pulsated/chattered one time like the ABS was actuating. The light came on then it went off, it's just screwd up. I paid about $20 from the dealer for the one rear sensor that bolts to the top of the rear differential. It didnt fix it, so I probly just wasted money.
We'll see what the shop comes up with tomorrow.

Rick
