Quick and dirty way to check preload (assuming you don't own scales): park the car on a flat floor, load weight into the driver seat to simulate driver weight, locate floor jack under rearend center section and slowly start jacking the rearend up. If you see the right or left tire raising first, you have preload on the other side. If you see the left rear tire clear the floor before the right side, you're likely going to be having problems.
