Ok I have been having a huge issue with my truck wanting to steer left going down a straight 4 lane road. If the road crown is slanted to the right its not as bad. If its to the left I have my wheel turned between 1&2 o'clock. Truck feels pretty unstable as well. I have rotated tires, switched tires and rims and even took it to the dealer to have them allign it under warranty. Well the toe was not at 0 degrees, so they adjusted that. the axle angle was in specs but there was a huge difference between the numbers on the machine. If I read the machine correctly the difference was 2 degrees between left and right. What can I do to fix this issue? Is it normal for this to happen? Dealer said they can not adjust for road crown wandering. Any help on this would be dearly apreciated!!!!!
