I ve got a wondering 06 4x4 with 59000mi. Just had new tires put on and had it aligned they said everything was tight and was a little out because it was pulling to the right slightly. It was doing this with old tires as well. Seems to have fixed the rt pull but wonders side to side.
Question is could it be the steering gear box or in the power steering system?
Any info would help

 

What tires were on it before and what tires did you buy? I had the stock Mich and bought the Hankooks (all stock size). I notice the Hankooks have more of a tendency to wander than the Michelins did. I also had the slight right pull that went away with the new tires. I just think it's the new tires in my case - going from a straight highway tire to an All-Terrain.

 

It had original BF Goodrich Rugged trail went to cooper zeon ltz both stock size

 

Wandering....

Put 1000 miles on the tires and it could go away.

Or lower balljoints could be bad. They will look good when they are lifted and wiggled, but put the weight of the truck on them and any wear will cause binding.

Don't use Moog joints!

 

X2 Moogs no good. mine wandered all over the place after install got them out and went to XRF and drives straight and true now with zero wander on new toyo open country at 285/75/17's.

 

I was wandering what you meant..........but I figured it out.
