22.05.2007: Axle nut
While the car is still on the ground, pop the cover in the middle of the wheel and loosen the axle nut using a 32 mm socket on a large breaker bar.

Lower control arm replacement on a 1996-1998 Saab 900 and 1999-2002 Saab 9-3. The guide also covers polyurethane bushings and ball joint boots. It's not necessary to unbolt the caliper (some pictures show it removed), but it gives you some extra room around the ball joint.

Tools:

  • 32 mm (1¼") socket: axle nut;
  • 24 mm socket: outer poly bushing nut;
  • 24 mm wrench: outer poly busing bolt;
  • 18 mm wrench: ball joint nut;
  • 17 mm socket: wheel bolts;
  • 15 mm socket: control arm to subframe bolt;
  • 13 mm socket: lower sway bar link nut, strut mount nuts;
  • 11 mm wrench: upper part of sway bar link;
  • 10 mm Allen key: caliper bolts (optional);
  • Torx T55 key: original outer bushing bolt;
  • torque wrench;
  • car jack and axle stands;
  • ball joint separator;
  • breaker bar;
  • two pairs of long nose pliers;
  • hacksaw;
  • hammer and rubber mallet.
