Coil spring, removing
- Clamp the suspension strut in a vise.
- Pretension coil spring using Spring Compressor ( V.A.G 1752/1) and Spring Holder (V.A.G 1752/4 ) until upper suspension strut is free.
Coil spring, removing
- When doing this, make sure the coil spring fits correctly in the Spring Holder (V.A.G 1752/4) - arrows -.
Coil spring, removing
- Remove collar nut from piston rod with special tools (T10001/3 ), (T10001/11) and (T10001/7).
- Remove individual components of suspension strut and pretensioned coil spring with Spring Compressor (V.A.G 1752/1).
Shock absorber, replacing
- Remove protective cap - 1 - and bottom spring washer - 2 -.
- Mark installation position of lower suspension strut to shock absorber.
- Loosen suspension strut - 3 - using plastic hammer and remove upward.
Lower suspension strut installation location
A Shock absorber/control arm bolt axis
I = left, B = 65° ± 2°
II = right, C = 87° ± 2°
- Drive suspension strut downward using plastic hammer according to self-provided marking.
With a new damper, transfer marking from old damper.
Note different installation locations on left and right sides.
Suspension strut trimming - arrow - must result in clearance to body.
Coil spring, installing
- Install suspension strut, lower spring support and protective cap.
- Position pretensioned coil spring on lower spring support using Spring Holder (V.A.G 1752/4). End of spring coil must rest against stop - arrow -.
Permissible deviation: ± 2°.
Upper spring support location
Position mounting bracket with spring support on pretensioned spring so that spring supports rests against end of coil spring - arrow -.
Permissible deviation: ± 2°.
Coil spring, installing
- Tension suspension strut with spring compressor vertically in Spring Mounting Tool (V.A.G 1752/2).
- Position individual suspension strut components. Make sure the end of the spring contacts the upper spring support.
- Tighten collar nut using special tools.
- Do not yet release tension on spring.
Mounting bracket installation location
- Loosen lower locking lever and turn upper suspension strut until Spring Mounting Tool (V.A.G 1752/2) scale is at 7°.
- Make sure the ends of the spring contact the spring seat at the top and at the bottom.
- Lock locking lever.
Seen in direction of travel
I = left
II = right
A Shock absorber/control arm bolt axis
- Adjust angle B.
B = 7°
- The Spring Mounting Tool (V.A.G 1752/2) arm - arrow - must align with the center of the mounting bracket.
- Now release tension on spring tensioner 1752/1 and remove.
- Check adjustment, repeat procedure if necessary.
Permissible deviation: ± 2°.
