Re: 2011 900 XP - Pulls hard to the left
Hi Eric and welcome to the forum!
Thanks for a detailed explanation on the concern and what you have done to try and correct the issue.
Reading what you have experienced, it is possible you have answered your own question. You stated that it is easier to steer left than right. I believe when you are moving forward, the force of the front tires on the ground will force the steering to go to the path of least resistance.
That said, I would disconnect the outer tie rods at the knuckles and check how the knuckles turn. Then check what I am suspecting. The steering gear/rack. If the steering wheel turns easier to the left than right, then I think you found the smoking gun.
Let us know what you find!
I'm just a soul whose intentions are good. Oh Lord, please don't let me be misunderstood.
