I'd like to know what they say. Even with the stuff you've done to yours, I still say they shouldn't shake. My only other guess would be your rims, but if you put new tires on them, you wore another set out, did you notice it before then? If you did, then I might start to think it could be the wheels themselves.

So here it is: There is no cure for the shaking steering wheel problem at 70 mph. The techs even went as far as contacting other Ford service centers in the vicinity and still nothing. They checked everything on the truck and everything was tip top. They told me that it had everything to do with the tires, not the truck. Again, I was told that when Ford changed their suspension on the 05 + f150 models, the suspension became very sensitive to the type of tires used. If the tires were perfect, the truck ran nice and smooth. However, if the tires had a defect in them, forget it. Here's another wrinkle. The same defective "New" tires that didnt work on my F150, worked flawlessly on a Chevy Tahoe that was in the next bay. The wheels also had nothing to do with the truck.

I asked them if the problem existed for every F150 out there starting in 05. They said no. They did say that even the brand new 09's were going to have the same problem.

So they admit that there is a problem with their suspesion, kinda. They blame the tires, but they work on other trucks. Makes me still think that ford is the ultimate culprit.

My next door neighbor is after market wheel and tire expert....since he sold wheels to dealers for years.
I mentioned your problem to him because it intrigued me. Here's what he said could be wrong.
1. bubble balance is not precise needs to be spin balanced.
2. check rim run out one could be slightly bent..."sprung"
3. rust on the hub to wheel surface can cause run out vibration always make sure mating surface is clean.
4. always torque the lug nuts to assure proper wheel contact with hub.

Have you done all these things to your truck........just a thought.

I appreciate the response to this crappy issue. Yes, the fellas at Discount took care of Step 1, Step 2 since I bought the wheels from them, Step 3, and Step 4. Ford rechecked what the Discount Tire fellas did and performed Step 1 through 4 as well. Here's where it got weird. I went back to Discount Tire, they rebalanced everything but this time, since they tried everything from the prior visits, inflated the tires past the recommended PSI settings, to make sure they were seated properly on the rims, then disinflated the tires back down to the required settings. It worked. I took the truck out on IH-35 and took it to 70 MPH, no problems. I gradually increased speed up to 85, very slight shaking but nothing to get into a twist over. The manager at Discount seemed to think that what may have happened when they overinflated the tires, was that they finally fit correctly on the wheel whereas before they hadnt. Also, he mentioned what also may have happened was this weird condition he described that took place when you buy tires with a tread pattern like the BFG All terrains. The tread being so thick actually causes the tire to shake because the weight of the vehicle is resting on each individual tread square, which in turn causes each tread square to wiggle in a circular motion. What?!! Anyway, the problem is gone for now. I will post up a couple of pics of my problem truck soon.

Glad to hear it worked out for you. The BFG excuse is crap though. I'm running those now and have about 500 miles on them and never had a shake or shimmy out of them.

I agree, I figure the guys felt bad that they couldnt figure it out so why not throw some B.S. at me, right?

I'm still trying to get the hang of this but I uploaded a few pics of my truck so you have a better idea of what my monster looked like, again thanks for the advice.
