So new transfer case is in and no problems. According to the tech, I am still having a problem with the speed sensors. At 52 mph reading on the front sensors, the rear is reading 57 mph and kicking the ABS light on. Is that a common problem with the 4.88 ratio of the gears or the eaton truetrac? Thats the only thing I can think of and being custom tuned, the dealer won't touch it. I emailed BBP about it, hopefully they get back to me.
