Coil Spring, Removing
1. Spring Compressor (V.A.G 1752/1)
2. Ring Spanner Insert AF 21 (T10001/7)
3. Ratchet (T10001/11)
4. Ring Spanner Insert AF 21 (T10001/3)
5. Spring Holder (V.A.G 1752/7)
- Clamp the suspension strut in the vise with the shock absorber fork installed.
- Mark the installation location of the mounting bracket to the T-pin on the shock absorber tube (felt-tip pen).
- Tension coil spring using spring compressor (V.A.G 1752/1) and spring holder (V.A.G 1752/7) until upper suspension strut is free.
- Make sure the coil spring is seated in the spring holder - 2 - correctly.
1. Spring Compressor (V.A.G 1752/1)
2. Spring Holder (V.A.G 1752/7)
- Remove the nut from the piston rod using the tools - 2, 3 and 4 -.
1. Spring Compressor (V.A.G 1752/1)
2. Ring Spanner Insert AF 21 (T10001/7)
3. Ratchet (T10001/11)
4. Ring spanner Insert AF 21 (T10001/3)
5. Spring holder (V.A.G 1752/7)
- Remove individual components of suspension strut and pre-tensioned coil spring with spring compressor (V.A.G 1752/1).
Shock Absorber, Replacing
- Remove the cap - 1 - and the lower spring support - 2 -.
- Loosen suspension strut - 3 - using plastic hammer and remove upward.
- Drive the spring plate onto the new shock absorber using a plastic hammer.
Coil Spring, Installing
- Install the lower spring support and the cap.
- Position the tensioned coil spring on the lower spring support. End of spring coil must rest against stop - arrow - (permissible play max. 2 mm).
Install mounting bracket with spring washer onto pre-loaded spring so that spring washer makes contact on end of spring coil - arrow - (permissible play max. 2 mm).
- Position individual suspension strut components.
- Tighten the nut using special tools - item 1 -.
- Align the marking on the mounting bracket to the T-pin on the shock absorber tube and release the tension in the spring.
Mounting Bracket Installation Position
- Install the spring mounting tool (V.A.G 1752/2) as shown in the illustration.
1. Rod, extended (V.A.G 1752/18-3)
2. Suspension strut adjustment gauge (V.A.G 1752/19)
3. Spring mounting tool (V.A.G 1752/2)
4. Clamping jaw (V.A.G 1752/19-1)
- Tension the suspension strut with spring compressor vertically in the spring mounting tool (V.A.G 1752/2).
- Tension the suspension strut so the pin - 1 - engages in the clamping jaw opening - 2 -.
- When tensioning, make sure the front damping adjustment valve - 1 - or electrical wiring connection - 2 - does not sit on the suspension strut mount - 3 -.
- Disengage the locking lever and set the pointer to the 0° position - arrow -, then tighten the locking lever.
- Adjust the mounting bracket so the suspension strut adjustment gauge (V.A.G 1752/19) for the respective side of the vehicle can be bolted to the mounting bracket.
Left Side
- Bolt adjust gage for suspension strut (V.A.G 1752/19) onto mounting bracket - arrows L -.
Right Side
- Attach the adjust gage for suspension strut (V.A.G 1752/19) to mounting bracket - arrows R -.
- Release the tension in the spring compressor (V.A.G 1752/1) and remove it.
• When releasing the tension, make sure the ends of the spring lie on the spring support stops in the mounting bracket and the lower spring support.
- Check adjustment, repeat procedure if necessary.
Permissible deviation: ±2°.
