The truck is pulling right with no defective parts found by multiple shops. I've been told this is due to "Crowing" of the roads to allow for run off. All the alignments have come back within factory specs. I have spent tons of time in the past few days testing different roads at different speeds. I even had the tires rotated and balanced today. Can the alignment shop make any adjustments to compemsate for this? Any help would e greatly appreciated.
Update: The vehicle is very loose at highway speeds. Steering wheel is moving side to side about 2" at 75mph. This is not vibration but actual side to side movement.

 

Hmm if its not alignment or balance, maybe check your power steering and brakes.

 

Or check to see if the right brake caliper is dragging on it's rotor.

And yes, an alignment shop can, and usually will compensate for "crowned" roads if asked. However, If it's pulling to the point that it's noticable, somethings wrong.

 

Gotto go with Bucko on this one...sounds like a rotor dragging, if everything else checks out. A crowned road won't be that bad.

 

Thanks for the help! Today we made a trip to Omaha and the truck was pulling right the entire time. When I would take my hands off the wheel the steering wheel would move from left to right about 2 inches in each direction. My wife was getting fustrated due to the fact the truck would not hold tight and was swearving all over the road. I plan on dropping the truck off @ Ford first thing in the morning.

 

ball joints maybe?

My dad has a '94 mustang that would dart around, replaced ball joints and it tightened it up.
