What is the purpose of the tension strut rod? Does this provide constant up/down tension on the spindle? One side of my rear is about 1/2" lower then the other. I attempted the rear strut mod, with almost new struts, and the rear of the car is not even side to side. I noticed that when I took the struts out of the spindles and pushed down on the spindles themselves, the side that is lower was very easy to move up and down, where as the side that is higher has much more up and down tension on it. I am wondering if I bent the strut rod while lowering the spindle on the strut? Of if the bushings are just shot on that side?
