Hi Rob I placed the 2x4 lengthwize up against the top of the spring on the side that was out of line and gave it acouple of wacks and it popped in. By proppng the front end up and letting the wheel hang in the air it takes the pressure off the spring. So determine the point on the top of the spring that is out of line, either to the left or right or front or back and place the 2x4 on that spot and have at er. Hope that helps. Jimbo
