2000 to 2006 ABC Rear Control Arm Removal Custom Tool Set
As shown in Kent's videos on replacing the rear strut and/or outer control arm bushings in an ABC SL500
Anytime you need to replace your rear shocks/struts, you must drop the rear control arm. If you are doing other rear suspension work, you may need to drop it as well. Kent came up with this tool kit when he was converting his SL500 to conventional coil-over shock absorbers.
