Well, I went with a remanufactured unit. Called the dealer with my vin # and they gave me the OEM part # for my truck. Bought the rebuilt unit from a local parts store that tried to cross reference the number. Of course when the shop changed it out it was the wrong one. The shaft was too long so the breaks were grabbing without using any peddle. They ended up just swapping the front shaft so the whole unit didn't have to be taken out again. Went on our trip to Utah and all seemed to work ok except a couple mornings when I got up the break lights had come on sometime during the night. Have not gotten around to checking that out yet.
