Check the tone rings for cracks, and the sensors for metal filings on the end.
If you feel the system pulsing the brakes when the truck is totally stopped, be sure the spark plug wires are routed correctly. If they aren't, the wires can magneticaly induce voltage pulses into the wires from the ABS sensors. That will make the ABS computer think a wheel is still turning, and the others are locked up.
