I have a F-150, 4 door, short bed, 4.6L, 4X2. A few weeks ago, I took the truck into the dealer and had new brakes and rotors installed on the front. After a couple of weeks I noticed that the front tires were beginning to wear unusually. I took the truck to a private shop and had it aligned. The included angle and SAI were adjusted. Just to make sure, the following week, I took the truck to the shop where I bought the tires to have them balanced and rotated. The shop could not get the front wheels off the rotors. The balanced the rear wheels and didn't charge me for the service. I immediately took the truck back to the dealer and explained what happened. I watched as the dealer mechanic undid the lug nuts and the front wheels came off. We had a little talk about the what just occurred as the dealer mechanic put the wheels back on the rotors. But I noticed that both wheels were teetering on the hub of the rotors. They would not sit flush against the rotors even when I pushed on the wheels/tires. The dealer mechanic then tightened the lugs forcing the wheels around the hub and onto the rotors. The dealer manager said this was normal, but I don't think so. I think it is causing my front tires to wear. They are cupping on the inside of the tires. Could it be that the dealer put on the wrong rotors? What is the solution?

 

first off welcome aboard!

did they use all ford parts or did they use aftermarket parts. if by some chance the rims were not flush against the surface, the steering wheel would vibrate your teeth out. could be a coincidence. not sure how to explaine about the wheels sticking on rotor. i have had problems with aluminum wheels on rotors but they usually have rust on mating surfaces.

 

Can't say anything conclusive about your truck, but as a general principle, you are right, the wheels should sit flush against the mating surface without having to hammer them in with an impact. Something is not right.
