When working on the Eldorado and Seville
Control Arms, first elevate the car then carefully position it to let the control arm dangle, remove the tire and wheel. Set a jack under the inner control arm end, take off the bar that links the lower control arm to the shocks and stabilizer, then detach and drop the control arm bolts at the inner end. Once you do those steps, lower the arm slowly one notch at a time to get the spring tension out of the way. Take down the lower control arm and set aside the coil spring. Place the coil spring and insulation pieces one by one, making sure the spring settles right when you put it on its bottom end and stays straight. Inject the jack to tug on the inner end of the lower control arm so the coil spring squeezes a bit, then attach the inner lower control arm nuts and bolts. Slowly lift the jack to put the front of the lowered control arm in its correct position for normal driving. Hold the suspension at normal ride height while you tighten: the stabilizer link nut to 44 ft-lbs; the
Shock Absorber nut to 75 ft-lbs; and the inner control arm nuts to 75 ft-lbs, making sure you tighten the control arms when they're in their normal riding position to stop the bushings from distorting. Finish by putting on the wheel, tire, and lowering the car, then verify that the rear wheels are aligned properly.
