Your caster is 2 full degrees lower on the right which is terrible. This can and will cause a pull to the right. I suspect your steering wheel is off to the left? Sorry, but you absolutely need another alignment.

That being said, evidently there have been cases of off center steering wheels due to the electronic rack and pinion unit. My shop has not had an issue with this yet. Absolutely my first step would be to correct the caster/alignment. When possible I prefer to have the caster about 1/2 degree lower on the left to compensate for road crown.

 

yeah they moved the caster or something i saw all red in the screen and at the end they turned green some of em they said caster dont do much to tire wear etc and im going to ford this week the steering and all feels softer, what about the rear toe and camber? Is it normal? Im going to ford see what they say steering is crooked to the left when driving straight and I’ll fix that alignment

 

The rear has nothing that is adjustable and it looks like your axle is slightly shifted. But honestly with the way they left your caster so messed up I question the competence of this alignment technician. Indeed caster is not a primary cause of tire wear but it certainly will ruin tires when it’s so far off that you need to steer the wheels to compensate!

 

it was perfect at 3.7 and 4.0 before? And slightly shifted to worry or not to worry about it? And ill have to find another place, after what ford says is wrong with the steering

 

Yes, your caster was MUCH better before. As for the rear axle, it’s nothing to worry about but the “thrust” angle needs to be accounted for or you will end up with an offset steering wheel. (This is assuming that the rear was even measured accurately.)

Ironically today’s equipment is so good that it creates a disconnect as to what the angles actually mean for the young pup mechanics. Lol

I learned on beams of light shining on a wall!! When I’m teaching my apprentices how to do an alignment it’s fairly easy to show them which way to turn a wrench to move a certain angle. The difficult part is getting them to understand what each angle means, why it’s important, and how it effects tire wear, handling, and straight ahead driving.

 

ok i will try to find another shop for the caster and offset steering? Like crooked? How is the thrust angle adjusted i also remember it was at 0.2 in my second alignment idk how it moved

 

Heh! I learned alignment when they were using measuring tools that magnetically attached to the wheel hubs (front only), a measuring bar was used to measure toe and thrust angle ? we don't need no stinking thrust angle . But, I can say that 'red' is bad and 'green' is good. As I recall, thrust angle has to do with the rear axle being plum (straight ahead) on both sides and not having the axle in a twist so as one side is further forward and the other further back which would cause the vehicle to crab down the road and also, by the way, cause the steering wheel not to be centered. I could be wrong, it's been a while. That rear toe reading may have something to do with the thrust angle or, you could have a wheel or axle slightly bent or simply, the precision of the equipment but, even that measurement is nothing to be concerned about in that regard. The numbers are tiny.

 

thats odd because i remember thrust angle was at 0.2 before and now more idk how it moved, should i worry about the rear measurements? Im gonna bring it to ford and see what they say about the steering the rear toe im sure was also lower before idk but this guys from goodyear said the alignment was perfect and that caster wasnt gonna damage my tired tread, all this is odd

 

Here is a pic of what thrust angle is. In you case, the reading is out of spec. Whether that's enough to make a noticeable difference in the driving characteristics or your truck, I can't say. All I know that being in spec is good, not being in spec is problematic at best and can lead to the truck crabbing which should be explanatory in the pic. The caster setting being out of spec will have more to do with it tracking straight down the road more than it will have an effect on tire wear. In most cases, your truck should be able to track straight down the road when you release the steering wheel. As I said in most cases. All roads are not the same. I would not be satisfied with any number that's marked in red.

 

yeah they moved the front caster somehow the thrust angle was lower before too, so the truck is going straight down a flat road but not on crown roads on flat roads its going straight if i hold it but its crooked if i let go it pulls slightly to the right on uneven roads, so ig the rear toe can be adjusted to adjust the thrust angle?
