Since the problem is not there with the stock wheels,and there with the aftermarket wheels.If the clips that hold the rotor can cause a problem,if there not there its the tire.Are these tires directional tires? if there not try switching the front tires,If the problem goes away are starts pulling to the right then you will know its the tire!

 

The tires are directional. Since I already had the right front tire replaced and it still does the same thing I was wondering could something in the back cause this.

I was thinking about changing one wheel at at time to the stock wheel and see if the problem goes away, but thought that probably wasn't a good idea because then I would be mixing wheel size and tire size which may not give accurate results.

This road force balance they was mentioned, does any ford dealer do that or do you have to go to a special shop?

 

Some of the ford dealers were i am have them,and some good tire shops will have them! I would say for sure you have a problem with left front tire.

 

That's what I would have thought but tirerack sent me a brand new left front under warrant and it is still doing the same thing.

 

You must be a liberal... kiddin'

You obviously need an alignment, but the question is why.
The dealer couldn't align mine lol.
Are you the only one that drive it?
Did you lend it to someone?
If you hit a curb the wrong way (no necessarily hard), it will throw the alignment off.

The only other thing I can think off, is your left caliper is dragging or freezing...
Check your pads on that side, see if you can notice excessive wear on them.

 

You can locate a shop that has a Hunter road force balancer by going to

This was in a matter of 3 to 4 days and I didn't hit anything and no one else drives the car. I don't think it's the dealers fault because it drives straight with the stock wheels I'm going to go talk to the alignment tech today and see what he says.
