Yep. Toyo MTs = right hand pull. Carli promotes its Bilstein high mount gas charged stabilizer will offset this. You may want to consider it.

Just out of curiosity.... why would a massive tire manufacturer want their flagship MT tire to have a pull in any direction?

They dont want it to pull, it occurs as an outcome of the tread pattern. Traction, balance, load capacity, and other attributes are of a higher priority. Ive had Toyo MTs in different sizes and they always did it. Its not a hard pull, but it is there. Its a pretty well known issue. .

Well, I installed the caster bushings that Hackenbush recommended and my truck is damn near dangerous to drive now. I don't understand how, for a few of y'all, it made your trucks drive so good. Mine feels like the steering sticks when i turn the wheel. When I'm on the highway going straight on a smooth road its not to bad, but if I'm on an uneven road or going around a curve its very hard to keep it between the lines. It did help my bump steer a little but not much. Maybe my front end is just screwed up but I really need to figure something out because I'm starting to hate driving my truck.

I'll let you know how i make out hopefully the end of this week or beginning of next at the latest. Got my radius arm drop brackets and they are getting powder coated now. As soon as they are installed the stock bushings go back in and i'll certainly let you know how things are. I know the feeling of not enjoying the drive in a brand new truck.

How much is your truck lifted & what kit did you use ?
Who put the shims in ?
Did you get a print out from any of the alignments you had done ?
Where are you located ?

My lift is a 2" ready lift type of spacer. It was one that was sitting in my shop from a 2011 model. As far as I can tell there is no difference in the spacers from that year. I did get a print out but I'm not sure where it is now. I know the caster said 2.4 and 2.5. I'm located in Katy Texas.

That's disappointing. What you describe is what my truck did after I leveled it and before the caster correction. The level effectively zero'd the caster angle on the steering knuckle and made the steering feel very floaty and would wander in the lane. The steering would not return to center on it's own after turning at an intersection and required that I steer it back. But I put on the adjustable caster bushings and ended up with 3.6 and 3.9 degrees on the alignment rack. It took the guy three tries to get it there but the difference is night and day. It restored the factory stiff steering and the truck handles as expected on the highway and around corners.

Sorry that you're struggling with this. I fought a wobble on my 2011 for most of the time I owned it. I know it's not a fun experience. On that truck I put on dual stabilizers which would wear out at about 20,000 miles. I replaced the OEM stabilizer with a Bilstein which helped some but did not solve. Finally I replaced the steering arm and ball joints on both ends and it resolved mostly. Not perfect, like my 2017 is now, but it was fine. I am convinced the steering arm ends and ball joints that were installed at the factory were just barely in spec. A Ford engineer once said that a system like the Ford suspension could potentially have each part just barely in spec but the spec for the overall system would be out of spec. He called it stacked tolerances and it's a real thing when several parts are marginal which cause failure or dissatisfaction with the whole.

He's the closest that I can suggest. They will fix your truck and be done with it.

I would actually be ok with how my truck drives with the factory bushings in if the bump steer wasn't so bad. I have a rough country dual steering stabilizer but it doesn't seem to help much.

Did you install a track bar relocation bracket? Or an adjustable track bar?

why would they not fix the "known issue"? Just doesn't make any sense whatsoever right?
