I have a 1998 F150 4x4 and got hit in the front drivers side wheel. I have changed the steering gear box because the pitman arm shaft was bent. I also changed front driver side wheel bearing assembly, and checked all tie rods and all bearings for play. They are all tight. There is no play in the idler arm.

When the truck is going straight forward the top of the tires slant inward, and when I back straight up the top of the tires slant outward.

What else should I check? Could it be a bent stearing knuckle? If a bent stearing knuckle, how do I check.

Any suggestions welcome.
