Alignment problem or tires?

[Erikclaw]

I have a coil over 8" kit on my 08 F250, with 37" Toyo MT's. I have had it to two different alignment shops but truck still wonders all over. If the road has any waves in it I am fighting to keep it in my lane. The steering wheel does not move, the truck just goes where it wants. This was never an issue when stock. Thought it could be the tires, was worse then as they wore became better. I just rotated them and now I am all over the road again. Any thoughts?

Toyos normally don't wander on the road. The truck should drive straight as an arrow if the suspension and steering geometry are all setup properly.
Most likely an alignment issue.

Have you had it aligned since the lift was installed?

overinflated tires.... do the chalk test and see if you are getting the whole footprint. when you rotated did the front tires have more wear in the middle than the outsides?

I have had the truck aligned twice since the lift was installed. Two different places. The last one installed an alignment cam on the passenger side.

The tires are inflated properly. Running 50 psi. The wear pattern is equal across the face. I do have the whole contact patch.

Do you have a print out with the specs?

What steering stabilizer setup are you running?

how wide are your tires, the grooves in the road are probably making it wonder. if you have a wider tire in my experience it will grab the grooves and track all over. think about it a skinn tire will just stay in the groove but wider tires like most of us run wont fit in the standard road way groove.

I am running Top Gun Customz twin bilstein set up. I have the reciept but there is no listing of the specs. Do you know what they should be?

The tires are a 13.5" wide. I have driven 40" boggers that are 18" wide and they are civilized compare to this thing.

I have the same issue, and i have a 8inch lift with toyos. and the same bilstein stablizers
From what i have gathered if the steering stabilizers are pressurized and one is stronger than the other it will push the tires around. I have yet to take the stabilizers off to see if that will fix the problem... i also have had the rig aligned multiple times once by an off road shop who told me about the stabilizer issue.... any one chime in if i could be wrong, or have a way to fix this issue
