Bump steer revisited

[totta Crolla]

Hi Bean,
l think that having rose jointed TCA's makes it worse, the standard bushed TCA's resist forward, back movement and help to push the caster arm length change forward to the caster arm bushes.
l'd imagine a car with a fully rose jointed front would be horrible.
If l could get the caster arm level at least the toe change would be in the same direction in bump and rebound. The standard Toyota setting is toe out in droop and bump toe in. A level arm would give toe out in both directions, probably not ideal either!
