06 XLS Pulls To Left @ Highway Speeds

[killitngrillit]

One day my truck decided it wanted to go left. Since then it has 3 4 wheels alignment 2 tire balance and rotates and no change to the amount of pull.

My local ford dealer did all the work; they say the front end is straight and gave me the readout of the alignments and they are spot on. Doubt it's a bad tire since they have been shuffled around several times.

What else could it be? I think they're stumped and unwilling to admit it.

I have 52,000 miles on, got it at 38. Didn't start pulling until about 48. No accidents prior to my ownership that I'm aware of. Tires were new at 39.

The 1st problem maybe the dealership. The dealership can only do the job by that the factory says. 2nd problem is, A really good frontend man will think out side the box. I owned several undamaged vehicles that had to be aligned some that out of the factory specs. They would track straight & no uneven tire wear after re-aligned. He would drive it with me riding with him to get a feeling for how it acted. You can't always bring a vehicle from the lot, put it on the machine and put it back on the lot. Ask around and /or call some alignments shops to hear what they would do. Alignments shops are like doctors, sometimes they just don't hear what your saying. good luck
