I installed a leveling kit on my 06 Supercrew FX4 over a year ago had it aligned and everything was great. last week I bought a new set of tires (33x12.5) which are the same diameter as i was running before just a little wider. I had the shop that i purchased the tires from do the alignment. I have taken it back 4 or 5 times within a week for it pulling to the left. cam kits have been installed it just still pulls left .

 

take it somewhere else. and have the original shop show you the print out of the specs after the alignment.

 

are you a nascar driver? sorry to hear about that. I had no problems with my 06....shocks.....balljoints? I dont know much about aligning a vehicle. Didnt know if any lf that could cause your problem.

 

I am going to a different shop today. they showed me print outs where they said it was in spec. but if it is in spec it should drive straight was my argument. yes i did feel like i was in a nascar race .

 

Moment Pwease.

I see 3 possibilities:

1) The truck is not able to be aligned

2) The shop is not capable of performing an alignment

3) The shop is not performing an alignment (but saying they are).

 

I go for number 2 and 3 . the truck drove straight before the tire swap

 

you have to be careful about this one. a lot of places will do this and still give a print out.

 

Do like I did last week and go back there while they're doing the alignment.

 

Then you may have a bad or underinflated tire.

What tire did you go with, by the way? I've seen on here that some guys are reporting a pull to the left after installing Trail Grapplers.

 

trail grapplers is what i went with. They said that they cross rotated the tires the first time i took it back . I dont know . I have an appointment with another shop in the morning.

 

check this out.

several more like it out there as well: https://www.f150online.com/forums/4482211-post9.html

 

that is crazy that you linked that thread . I had just emailed him about his tires. i ran the terra grapplers for about 60,000 miles before i swapped to these tires and had no problems.
