Attach the upper control-arm assembly to the pair of bolt studs on the frame from which it was removed and start the nuts onto the studs. Retrieve the shims you removed and marked earlier. Place them back into their original locations, keeping the tabs facing upward. Finish tightening the bolts. Attach the new upper control-arm bumper between the frame and upper control arm by pushing it into the predrilled slot in the frame. To reinstall the lower control arm, simultaneously sandwich the coil spring between the frame and lower control arm by placing the coil spring into its obvious position against the upper frame. Then, hinge the lower control arm upward to sandwich the coil spring between. Use a jack to raise the lower control arm which slightly compresses the spring assembly. (Normally the weight of the engine in the car is enough counterweight to compress the spring; however, our project car’s engine is out for rebuilding, so we had to use a spring compression tool to accomplish this.) Now reattach the control-arm–shaft bolts to the frame. Keep the pressure of the jack on the spring while you reinstall the spindle. The jack may need to be raised slightly to narrow the spread between the control arms. The spindle attaches to the upper and lower ball joints to tie the whole assembly together. Install and tighten the bolts that attach the spindle to the ball joints and set the cotter pin. View Related Article
