Bump steer Hell

[David Pozzi]

Is it .100" at the rim or at the tire tread?
Some toe-out under bump is better than having toe-in under bump.
I don't think .100 is too bad, you would probably not feel it, but if you could get below .050" that would be better.

If it's a rear steer rack, lowering the outer rod ends will reduce toe out under bump.



The inner pivots should line up with the lower A arm bolt hole axis in both height and width.

If you can get the bumpsteer under control for the first two inches of bump, I'd not worry much about the rest of the suspension travel unless it's really going crazy.
