Review on Dorman 521 872 Suspension Control Select by Maurice Arnold

I recently spent about 6 hours installing the upper rear wishbones. After jacking up the car and putting it on stands, I removed the wheel and began loosening the three bolts holding the lever. A month earlier I sprayed the screws liberally with a hammer. I recoated the screws with a penetrating spray. Being careful not to break the bolts, I used a Mapp gas torch to heat the nut and remove one side of the lever. The next two internal screws took much longer due to availability. Extensions, wobble extensions, versatile swirls and lots of penetrating spray did the trick. After cleaning the threads of the bolts, installing the levers was easy. A separate jack is handy for raising the lower arm to align the two internal bolts. Now I can adjust the camber and adjust the rear camber. Rear tires no longer wear out. How lightness you can adjust with simple hand tools.
