Suspension Help

[Scarface]

It sounds to me like you need to loosen up all of your suspension bolts, center the housing under the car and then retighten. If you have to adjust the upper arms to maintain center that is what you'll have to do. You may even end up slotting some of the holes to get the rear end where it needs to be.

What is the best way to measure everything to makesure it is in the center? I new to this so I was just wondering if anyone had any ideas?
