It's best to have it looked at by a qualified suspension techie.

yep, the caster angle is responsible for maintaining the straight-line stability assuming the camber and toe settings are within range. to offset the roadcrown or the arch of the road surface when viewed crosswise, the camber is set more positive on the port side(driver side) or the caster is more positive on the starboard side (pax side). the S.A.I=K.P.I. or the steering axis inclination is equal and similar to king pin inclination and is responsible for returnability to straight ahead from a turn when the vehicle is in motion
