Just picked up an 06 F-150 with 305/40/22 tires the trucks steering doesn't want to return to center when driving at slower speeds. I think its the wide tires and maybe the truck has too much caster. Higher speeds are better.
Thoughts?

Possibly alignment?

I just went and inspected the steering shaft and the little u-joints look nasty. I think a good soaking with some Sea Foam will help this situation. If not, I wonder if an underdrive pulley on the p/s pump would boost the pressure a bit?

Quoted from another forum - "This my sound to easy but the same thing happen to me . 04 5.4, its the same feeling. took it to the car wash opened the hood an directed the spray on the steering shaft that connects to the [rack an pinion] where the UJOINTS are top an bottom. an my power steering came back!!! the only thing it could have been dirt an ice ...got home took a can of garage door lube sprayed the two jouints. its been TWO MONTHS..works great.."

I will be getting the alignment checked especially the caster. I may see if it can come a bit negative to help.
