Cross Caster Left 2.8 Right 4.2 Vehicle Pulls Left HELP

[rreid]

My vehicle has an annoying pull to the left. I noticed this after I installed new tires.

My dealer (very friendly people) checked my alignment… (see photo).

Left Caster is 2.8
Right castor is 4.2

My steering wheel needs to set about 10 to 15° clockwise for the vehicle to track straight, and I’m constantly “tugging” ok the steering wheel clockwise (to the right) regardless of the road crown.

I’m not sure if I understood my dealer correctly that castor cannot be directly adjusted??

By now we probably have all seen John from OWL explain how he adjusted his caster by adjusting his eccentrics…

I have my fourth follow up appointment now at the dealer, I don’t know how a 1.4° cross caster variance would result in anything other than the vehicle pulling… not at all a neutral steering experience!!

How do we know that those eccentrics are properly set if they’re not properly set is it expected that the result would be a caster variance?

Anyone run into this problem before?

Appreciate your thoughts in advance!!

Best

You cannot adjust caster on each side independently. If one changes so does the other by exactly the same amount. If those are your real caster numbers then Ineos owes you a new front axle.

That spreadsheet with those caster numbers are with the Ineos dealwr here provided me with… they use their other dealership for their alignment system so not to be misleading. That is actually my vehicle. A 2024 Grenadier.

And in looking at the video, John did from OWL it would appear as though you could adjust one side and wouldn’t it have the opposite reaction to the other???
