Removing coil spring 1 -  Spring compressor -V.A.G 1752/1- 2 -  Socket -T10001/7- 3 -  Ratchet -T10001/11- 4 -  Socket -T10001/3- 5 -  Spring retainer -V.A.G 1752/7- –  Clamp suspension strut in vice with shock absorber fork attached. –  Mark installation position of mounting bracket relative to T-bolt on shock absorber tube (use a felt-tip pen). –  Compress coil spring using spring compressor -V.A.G 1752/1- and spring retainers -V.A.G 1752/7- until top spring seat is free.

–  Ensure that coil spring is correctly seated in spring retainer-2-. 1 -  Spring compressor -V.A.G 1752/1- 2 -  Spring retainer -V.A.G 1752/7-

–  Unscrew nut from piston rod using tools -2-, -3- and -4-. 1 -  Spring compressor -V.A.G 1752/1- 2 -  Socket -T10001/7- 3 -  Ratchet -T10001/11- 4 -  Socket -T10001/3- 5 -  Spring retainer -V.A.G 1752/7- –  Take off suspension strut components and compressed coil spring together with spring compressor -V.A.G 1752/1-.

Renewing shock absorber –  Take off protective cap -1- and bottom spring seat -2-. –  Knock spring plate -3- loose using plastic-headed hammer and lift off. –  Using plastic-headed hammer, knock spring plate onto new shock absorber.

Installing coil spring –  Install bottom spring seat and protective cap. –  Position compressed coil spring on bottom spring seat. End of spring coil must make contact with stop -arrow- (maximum permissible clearance 2 mm).

Install mounting bracket with spring seat on compressed coil spring so that spring seat makes contact with end of spring coil -arrow- (maximum permissible clearance 2 mm). –  Fit component parts of suspension strut. –  Tighten nut using special tools → Item. –  Align marking on mounting bracket relative to T-bolt on shock absorber tube and release tension on spring.

Installation position of mounting bracket –  Attach strut holder -V.A.G 1752/2- as shown in illustration. 1 -  Rod, extended -V.A.G 1752/18-3- 2 -  Suspension strut adjuster gauge -V.A.G 1752/19- 3 -  Strut holder -V.A.G 1752/2- 4 -  Clamp plate -V.A.G 1752/19-1- –  Clamp suspension strut with spring compressor vertically in strut holder -V.A.G 1752/2-.

–  Clamp suspension strut so that pin -1- engages in recess on clamp plate-2-.

–  When attaching suspension strut to clamp, make sure that front damping adjustment valve-1- and electrical wiring connection -2- are not resting on strut holder-3-.

–  Release clamping lever and set pointer to 0° -arrow-. Then tighten clamping lever again. –  Adjust mounting bracket so that suspension strut adjuster gauge -V.A.G 1752/19- (for relevant side) can be bolted onto mounting bracket.

Left side of vehicle: –  Bolt suspension strut adjuster gauge -V.A.G 1752/19- to mounting bracket -arrows L-.

Right side of vehicle: –  Bolt suspension strut adjuster gauge -V.A.G 1752/19- to mounting bracket -arrows R-. –  Now slacken off and remove spring compressor -V.A.G 1752/1-.   Note When slackening spring compressor, make sure that ends of spring are in contact with stops on bottom spring seat and spring seat on mounting bracket. –  Check adjustment and repeat procedure if necessary. Maximum permissible misalignment: ± 2°
