If your truck drove good before you changed the wheels & tires, I would say that the wheels & tires are causing your "pull". What load range tires are required for your truck? What load range tires did they sell you? I would bet that your new tires are a light-duty tire that cannot run the factory recommended tire pressures for you truck. I have run into this hundreds of times as the alignment guy at the Ford dealer.

The tires I had on were "E" (10 ply), and the ones I put on were "D" (8ply). One more thing I just thought of...with the new tires they would rub just slightly against the bumper. I eventually just ground off the bumper corner a bit, but before I did that I tried to pry the bumper forward by putting a jack between the bumper and the front axle. That couldn't have done anything, could it??
What I did was was remove the bumper and and replaced the bolts with longer ones and threw a bunch of washers on it to shim it out.

Hey Copedawg - that would have been a good idea. Oh well, as I said I just ground down the edges of the bumper and it worked. You can't even notice unless you get under the truck. hey, BTW, thanks for the advice on the signature!

That depends on how much pressure the jack had on the front axle and exactly where it was located.

funny this should come up, couple of weeks ago while trying to find the source of a noise i found the centerpin on the front driver side leaf pack was gone! when i took the pack apart there was just a small nub left in the spring pad not doing anything! glad i found it before something bad happened!
this is a pic of my bronco but i am running a sterling so it is exactly the same. the center pin is, well, in the center of the plate

Dave I had the jack wedged betwen the left corner of the bumper and right by the rotor. I'm wondering, though, because all that happened is that the bumper would bend forward, and then when I removed the jack it would just spring back to it's original position.

I was just wondering. YOu said you got d tires on it now. Are the max inflation pressures on the sidewall 80 psi? If they are 50 then they can cause this.
And if they do say 50 then you need to go back to that store and demand the proper tires be put on your truck. Federal law requires them to put tires rated at or better than what your door sticker calls for. And I know it calls for 80 psi rear.

And if you look at the weight rating, most likely the 285 D rated tires will have a higher weight rating than the 235 E tires.
