To check your Bump steer in your own shed just do the following;
1. Jack up the front and remove front wheel and coilover
2. Get and old Rim... on the outer bottom of the rim weld a piece of 25 x 25 rhs about 2metres long
3. put the rim on the car the rhs should be sticking a metre and a half out the front of the car
4. with the rim hanging approx. 75mm down on ride height mark the ground at the end of the rhs
5. lift the rim up all the way and watch if the rhs moves in or out at the end
for zero bump steer the Rim should travel up and down and the end of the rhs shouldnt move in or out
If the RhS moves out when the rim moves toward the top of its stroke the rack needs to be lifted

This is only a primitive method for those of us that dont have access to do it on a wheel alignment machine but it tells you exactly whats happening
