This might sound like a silly question, but, what the blimin hell in "bumpsteer"?
I know a fair bit about cars but have never heard of this.
Can anyone tell me what it is, where it fits and what it does
could you tell me with minumum pi$$ taking??
cheers

Bumpsteer is where the front suspension geometry is such that as the suspension compresses the steering angle changes.
Under dive, where both front wheels compress equally either from braking or hitting a speedbump or similar, then both wheels will move the same and the car won't steer but tracking will change. Not ideal but not too bad. But hit a bump with one wheel and that wheel will steer and the other stay the same so the car will swerve one way or another. Also when the car rolls one wheel goes into bump, the other rebound so again the car will steer itself. Not big or clever.
Bumpsteer mods try and adjust the geometry so that as the suspension moves overs it's normal travel the change in steering angle is minimised. On a simplistic level this can be thought of as trying to make the track rod and the lower suspension member parallelm so that they move together without adding any steering effect. On a scoobie this is done by changing the height of the rack to change the angle of the track rod. On other cars it can be by changing the height of the steering arm on the upright or adding a spacer between the steering arm and the track rod.

How come TSL and Powerstation charge so much for the 4 wheel alignment?
I've been offered 4 wheel alignment by Laserline equipment, my choice of settings if I want, for £40 maximum, locally.
Just wondered?
