The first thing anyone who is diagnosing a steering problem needs to do is have the wheel alignment checked by a shop able to provide some hard numbers on caster, camber, and toe. Until that happens, any advice anyone gives you is pure speculation.
A vehicle will pull toward the side with the most positive camber, and/or to the side with the least positive caster. For instance:
Camber: Right side +3 Left side +2- - - - -the vehicle will pull toward the right.
Caster: Right side +3, Left side +2- - - -vehicle will pull left.
In areas with a normal amount of road crown for rain drainage, it's customary to run equal camber on both sides, and 1/2 degree less caster on the driver's side to make the vehicle track straight and compensate for road crown.
Toe adjustment on a vehicle with the tie rods behind the spindles is usually slightly toed-in. Some vehicles with the tie rods ahead of the spindles such as early-1950's Fords get a little toe-out. Both designs tend to move toward a zero toe measurement when in motion.
