I beg to differ - it is normal, the inner tire will always carry a greater angle than the outer and the shorter the vehicle wheelbase, and the tighter the lock, the more pronounced and noticeable this is - and yes ackerman angle, or ackerman geometry explains why.

You should see exactly the same phenomenon turning both left AND right, if this is not so, you most likely have something bent underneath. Under normal circumstances, the only alignment adjustment on these vehicles is the toe-in, and that will not cause a greater "throw" to the left than the right, if it is incorrect, you'll still end up with the inner wheel at a sharper angle than the outer
when turned in both directionsGoing slightly off topic - the illustration shows how the ackerman angle is derived based on distance between the kingpins and the wheelbase of the vehicle, I've seen countless build threads where either one or the other has been changed, the Mike Hagen mod, SAS conversions, RUF, etc. I wonder how many people pay attention to this.
