Undo three bolts holding the control arm to the subframe. One is at the
front of the arm, and two more hold the aluminium housing of the big rear
bushing. It might also be a good idea to slacken the rear bushing retainer
nut - you have more leverage while it's still on the car.

Lower control arm removal and bushing replacement on a Saab 9-5.
The original bushings were worn and cracked, the hydraulic rear
bushings went dry and lost most of the oil, so a fresh set was
needed.
Saab sells replacement rear bushings as a complete assembly with a new
aluminium housing, but we're installing a polyurethane insert, so the old
bushing needs to be pressed out of the housing.
A hydraulic press should greatly speed up the rear bushing removal, but
since it's not a common household appliance, we will be using a hacksaw
and a gear puller.
Tools:
- 18 mm socket: rear bushing retainer nut, ball joint nut (optional);
- 17 mm socket: wheel bolts;
- 15 mm socket: control arm bolts;
- 13 mm socket: ball joint screws (optional);
- 8 mm socket: plastic shield screws;
- torque wrench;
- car jack and axle stands;
- breaker bar;
- gear puller;
- hacksaw;
- hammer and rubber mallet.
