I think your truck pulls because of the alignment or because of an electronic steering problem. The specs you listed are not the whole story. Can you post an image of a printout? There could be bent or defective things that aren't shown just in the numbers you posted.

The very slight cross caster (0.1 R) is leading the vehicle left, but not enough to have an impact. The toe on the rear right is also doing the opposite thing and it has more of an impact. All vehicles should be compensated for road crown to keep them from pulling right. While these compensations are usually small, your vehicle from what you have posted has the opposite.

Speaking of numbers, can we see the thrust angle and/or geometric center line numbers from the alignment?

I'd add 3psi to the right front tire and go for a ride. If the pull is gone or largely mitigated, the issue is "alignment" related. If not then it is likely steering rack related since you eliminated tires and brakes already.

Was the steering wheel angle sensor calibrated after each alignment? If not this can cause the power assist to try and help you steer right when you want to go straight.

If you get another alignment do two things. Have them set RH caster to the max spec, and LH to the minimum spec. Also have them calibrate the steering wheel angle sensor.

Honestly get your tires rotated, swap the front two tires and I bet it pulls the other direction afterwards. We see it every day. Those alignment specs are fine.

I rotate every 3000 miles. Don't matter what postion the tires are in.

Damn they didn't do **** for adjustment lol. Only front toe. Shouldn't have any pull

I always wonder where the steering wheel is pointed when they align it lol.

I just got an alignment after replacing tie rods at a ford dealer. Drove away and the steering wheel was crooked. They said it was my tires, but they could center the steering wheel, I said make it straight. It pulls straight, and wears tires just fine.

I think the problem is most techs are too lazy to properly fix the steering wheel while they do the alignment. If the steering wheel isn't forcibly held in position while doing the alignment, it can very easily be moved by the tech when adjusting toe. This of course means that when they unknowingly adjust toe to more to hit the target toe for each side and thrust angle, but with the steering wheel off center.

Depends on alignment machine and program. We have the brand new Hunter alignment machine with the clamp on heads. Only steering wheels we lock down are jeeps and dodge's and such with a drop-drag link system. Other than that, using WinToe you can move the wheels all over the place and the toe stays locked. But most techs are too lazy to redo the alignment if the steering wheel is off, they just "get it in the green" and hope the customer doesn't complain

My steering wheel was centered. Been to three alignment shops get the same result every time including from Ford.
