To start the process of changing control arms on different models of Cadillac made between 1990 and 1998, first lift and support the vehicle safely, remove the wheel and tire assembly, and disconnect such parts as height sensors, stabilizer bars or shock absorbers. In order to change control arms in Deville and Fleetwood models made between 1990 & 93 there is need to remove suspension adjustment link coil spring as well as ball joint stud and use specific tools to separate knuckle from ball joint. Put back the control arm then tighten all necessary nuts to given torque values then lubricate them. The steps for Eldorado and Seville models made between 1990 & 92 include disconnecting brake components, removing knuckle pivot bolt, lowering the suspension in order to take off the control arm. The control arm should be positioned and reattach components before tightening relevant bolts/nuts to specific torque values that would ensure proper suspension height. On Eldorado and Seville models manufactured from 1993 to 1998, removing lower control arm involves disconnecting stabilizer bar and shock absorber; removing inner lower control arm nuts and bolts; safely lowering control arm to relieve spring pressure. At this point the lower control arm is reinstalled with correct spring orientation by tightening all nuts/bolts at specified torque values. The sequence in which upper control arms are removed & installed includes disconnection of engine-specific components, removal of control arm bolts and ensuring right torque values for nuts. Finally reinstall the wheel/tire assembly while rear wheel alignment check is recommended after doing control arm work.
