Axle shaft assembly removing and installing

— Apply parking brake and shift transmission into reverse.

— Remove wheel hub center cap. Loosen stub axle nut (32 mm socket wrench) through opening in center of wheel.

— Loosen rear wheel lug nuts.

— Release parking brake and shift transmission into neutral. Raise rear of car and support it securely.

Make sure the car is stable and well supported at all times. Use a professional automotive lift or jack stands designed for the purpose. A floor jack is not adequate support.

— Remove rear wheel. Remove stub axle nut.

^ With car close to ground level use floor jack under trailing arm to relieve suspension load on shock absorber. (Brake backing plate shown removed for clarity.)

Porsche special tool P 289 a may be used to hold rear suspension in a compressed position while working on the rear shock absorber bolt.
