Rear Suspension

Removing and installing drive shaft





Preliminary work

1. Loosen axle nut (vehicle on ground, also press the brake while doing this/two fitters required).
2. Remove wheel.

Information
^ To prevent damage to the drive shaft, rear axle support side member or transmission flange, a protective tube (shop-made) 00000 must be pushed over the drive shaft or the drive shaft must be secured.
^ During removal of the drive shaft, the wheel bearing housing remains in the vehicle and is swiveled outwards at the top side.

1. Fit protection -arrow- for drive shaft. Release inner end of drive shaft from the transmission.

2. Using universal drive shaft/wheel hub extractor as of model '86 NR.87-1 carefully press out the pin of the drive shaft until the shaft can be moved by hand.

Removing/fitting parking-brake cable

The parking-brake cable must be disengaged from the parking brake lever in the passenger compartment before the drive shaft can be removed. Disengaging the parking-brake cable includes:

^ Undo parking-brake lever (do not operate until after fitting! Self-adjusting!)
^ Open cover of oddments tray in center console.
^ Remove bottom of oddments tray in center console.
^ Disengage the relevant parking-brake cable to the side of the turnbuckle.

3. Pull protective sleeve of parking-brake cable -2- from guide tube on underbody -1-.

4. Detach both upper axle struts from the outside of the wheel bearing housing.

5. Undo the holder for the brake hose/wear indicator -arrow-.

6. Loosen connecting link for anti-roll bar -1- and spring strut -2- on the wheel bearing housing.

7. Carefully pull wheel bearing housing outwards. Guide the parking-brake cable and remove the drive shaft (assistance of second fitter required).

Caution
Increased risk of accidents if the wheel carrier is raised improperly!
^ Injuries and material damage are possible.

-> Do not raise the wheel suspension higher than the normal vehicle position (vehicle resting on wheels).

-> When raising the suspension, use a suitable intermediate layer (hard rubber).

-> Do not damage the brake cover plate.

Information
^ Screws are Dacromet-coated and must not be greased.
^ Grease the thread of the axle nut with Optimoly HT.
^ Grease the toothing of the drive shaft lightly with Optimoly HT.
^ To prevent damage to the drive shaft, wheel bearing housing or transmission flange, slide a protective tube (shop-made) 00000 over the drive shaft.
^ Use new screws and lock nuts.
^ Observe correct tightening torques. Tighten the connecting link for the anti-roll bar in three steps (step 1: tighten to 50 Nm (37 ftlb.)/step 2: loosen by 90°/step 3: tighten to 65 Nm (48 ftlb.)).
^ The parking brake is self-adjusting. If the basic setting of the parking brake is correct, further adjustment operations on the parking brake lever or on the turnbuckle are not necessary.
^ Always check the bellows for damage and if necessary, replace them, if continuing to use the drive shaft.

1. Pull the wheel bearing housing carefully outwards and run in the drive shaft (2 fitters required). Screw on axle nuts. Use protection for drive shaft.
2. Fit the two upper control arms on the external wheel bearing housing.
3. Slide the protective sleeve of the parking-brake cable -2- on the underbody onto the guide tube -1-. Ensure it is seated correctly!





Push on protective sleeve

4. Engage brake cable in the turnbuckle at sides.

5. Fit lower spring strut, connecting rod for anti-roll bar, inner drive shaft on transmission and mount for brake hose/wear indicator.

Observe the anti-roll bar setting, i.e. position of connecting link (suspension/stabilizer) on anti-roll bar, on the 911 GT3/GT3 RS!

Rear anti-roll bar setting: 911 GT3/911 GT3 RS (997)/January 2007 = Position -3- (figure shows position -2-).

7. Check parking brake adjustment and adjust if necessary.

Subsequent work

1. Fit wheel.
2. Tighten axle nut (vehicle on ground, also press the brake while doing this/two fitters required).

Checking wheel-alignment values

Check wheel alignment values and adjust if necessary.
