Special tools, testers and auxiliary items required
• Friction meter (VAS 6222)
Other required special tools and equipment not depicted
Removing
- Remove the steering gear. Refer to => [ Steering Gear ] Steering Gear.
- Clean steering gear in area of adjustment screw.
- Tension steering gear using 2 bolts M10 x 60 as depicted in the illustration.
- Determine starting torque of steering.
- First turn steering toward right in direction of travel until it stops.
- Now turn steering uniformly toward left until it stops on friction meter, e.g. (VAS 6222). Read off steering torque while doing this.
Specified value: 3 +/- 2 Nm
1 Friction meter, e.g. (VAS 6222)
2 24 mm socket
- Remove clamp for bellows at left - 1 - and pull off bellows from steering gear housing.
- Turn steering into straight ahead position using (T10304).
For this purpose, dimension - a - = 25.5 mm.
- Rotate steering gear in mounting bracket so that thrust piece with adjustment screw points upward.
- Now slide boot onto steering gear cover again.
- Drill the 6 peenings out using a 4 mm drill bit until reaching dimension - a -.
Dimension - a - = 3 mm
Do not Drill Deeper than 3 mm.
- Vacuum up drill shavings completely from steering gear housing using e.g. wet and dry vacuum cleaner (V.A.G 1373).
- Remove the adjustment screw.
- Remove sealing ring - arrow -.
- Pull steering rack in direction of thrust piece so that it disengages from steering rack.
- Simultaneously pull out hydraulic thrust piece from steering gear housing using suitable pliers.
• If corrosion, damage, wear-out or first signs of soiling on steering rack can be seen, complete steering gear must be replaced.
• If no grease film is visible on steering rack, steering gear must also be replaced completely.
Installing and Adjusting
- Coat new thrust piece - arrow A - (contact surface at steering gear), sealing ring and hole in steering gear housing - arrow B - with grease (G 052 192 A1) supplied.
Do not use other grease under any circumstances.
- Install hydraulic thrust piece and sealing ring - arrow - by hand.
- Tighten new adjustment screw to 40 Nm.
- Peen the adjustment screw 6 times - arrows - using a punch.
Punch points must be applied 2 graduation lines next to the drill out punch points.
- Mark one graduation line of adjustment screw on the steering gear housing - 1 -.
- Remove the adjustment screw 5.5 graduation lines toward left - 2 -.
While doing this, a loosening torque of at least 15 Nm must be obtained.
If Loosening Torque is Not Obtained:
- Tighten adjustment screw to 40 Nm again.
- Reinforce the 6 peenings using a punch.
- Check applied marking of adjustment screw graduation line on steering gear housing, apply the marking again if necessary.
- Remove the adjustment screw 5.5 graduation lines toward left.
A loosening torque of at least 15 Nm must be obtained.
- Turn steering using (T10304) from left stop to right stop.
No hitching or jamming may occur while steering through. If there is, surface of steering rack is damaged and steering gear must be replaced.
- Install left bellows onto steering gear housing with new clamp.
- Determine starting torque of steering.
- First turn steering toward right in direction of travel until it stops.
- Now turn steering uniformly toward left until it stops on friction meter, e.g. (VAS 6222). Read off steering torque while doing this.
Specified value: 3 +/- 2 Nm
1 Friction meter, e.g. (VAS 6222)
2 24 mm socket
If Steering Torque is Exceeded:
- Loosen hydraulic thrust piece adjusting screws about one graduation line (turn adjustment screws toward left).
- Then, check steering torque.
If Steering Torque Falls Short:
- Install hydraulic thrust piece adjusting screws about one graduation line (turn adjustment screws toward right).
- Then, check steering torque.
- Steering gear, installing => [ Steering Gear ] Steering Gear.
- Perform vehicle alignment => [ Wheel Alignment ] Wheel Alignment.
- Perform basic setting for Steering Angle Sensor (G85) via vehicle diagnostic tester "Guided Fault Finding".
- Then perform basic setting of steering system via vehicle diagnostic tester "Guided Fault Finding".
