Mine had a pull to rite after i rotated the tires back to front. Rotated tires back & pull went away. Took it to dealer & they rotated tires back to front & rite to left. Also did a balance first on all tires, service manger test drove after every change & said the steering wheel was off a little to the rite. Finally put on wheel alignment machine & checked said both sides were same according to machine spec. Finally installed a shim in rite side & it fixed the problem for now...
Mine presently has the pull to the right, the dealer has already tried once to re-align the truck, however their alignment computer did not have the 2011 programming yet, so they tried based on 2010 programming......they said the truck fell within specs.
Initially, along with the pull to the right, the steering wheel was also offset to the right a little, and after the dealer tried the first time to align the truck, they rotated the front tires and re-aligned it. The truck fell within specs, based on 2010 programming, but still pulls to the right, only now the steering wheel is offset to the left the same distance as it was when offset to the right.
After the alignment. took the truck for a test drive, initially appeared ok, but the roads are crowned pretty bad, so I accepted the truck. When I got the truck back on the interstate, on a good flat patch, that's when I noticed the truck still had the pull to the right and the steering wheel was offset to the left this time. So the truck is headed back in couple of weeks for another attempt at re-alignment.
