pull...
If the pull is worse loaded, try backing up a bunch and hitting the brakes to set the rear adjusters. I found this to help mine. The dealer will usually swap the front calipers side to side. This will cure it for about 10k miles and it will pull toward the other side while braking.
Lubing the pins will help. The quads always seem to pull toward the low side of the road and with the wind. If you experience a pull while driving, jump over to the oncoming lane and see if the pull goes the other way. Chrysler has openly admitted that the Qcs and X-cabs will easily pull on sloped surfaces and in the wind.
