Dismantling and assembling suspension strut

Dismantling

Note:

Pay attention to differences in component design between "standard, sports and heavy-duty running gear".

• ‒ Clamp suspension strut holder -V.A.G 1752/2- in vice.
• ‒ → Insert suspension strut in suspension strut holder V.A.G 1752/2.
• ‒ Use screwdriver to prise out cap => Page 42-33, -Item 1-.

• ‒ → Position coil spring with tensioner -V.A.G 1752/1- on spring seat.
• ‒ Pay attention to correct positioning of coil spring in adapter V.A.G 1752/3.

• ‒ → Pre-tension coil spring with tensioner -V.A.G 1752/1- until upper spring plate is free.
• ‒ Unscrew hexagon nut from piston rod whilst providing support with Allen key.
• ‒ Detach appropriate components.

Assembling

Note:

Left and right suspension strut are identical.

• ‒ → Clamp shock absorber in suspension strut holder -V.A.G 1752/2-.

• ‒ → Roughly align spring seat and packing ring as shown in direction of shock absorber eye.
• ‒ Fit pre-tensioned coil spring. End of spring winding must make contact with packing ring stop provided.
• ‒ Insert protective cap, bellows, bellows support ring, additional spring, ring, lower washer, bearing ring and spacer.

• ‒ → Fit spring support.

• End of spring winding must make contact with stop -arrow-.

• ‒ → Fit upper spring plate.
• ‒ Stamped nuts of spring plate must be positioned in recesses of spring support -arrows-.

• ‒ Fit bearing ring, dished washer and new lock nut.
• ‒ Attach adjustment gauge V.A.G 1752/8 to suspension strut holder V.A.G 1752/2.

• ‒ → Position adjustment gauge V.A.G 1752/8 on upper spring plate and secure with hexagon bolts.
• ‒ Lock upper locking levers of suspension strut holder V.A.G 1752/2.

• ‒ → Release lower locking levers and turn upper spring plates until reading on scale of suspension strut holder -V.A.G 1752/2- is 0°.
• ‒ Make sure spring ends are in contact with stops of spring support and spring seat.
• ‒ Lock levers.

• ‒ → Tighten lock nut with socket attachment 3379 and counterhold 3079 to 25 Nm.

• ‒ → Turn spring seat => Page 42-35, -Item 18 until stop is at end of spring.

Note:

In doing so, take care not to damage surface of spring.

• ‒ Carefully slacken off coil spring, paying attention to correct positioning of coil spring and top and bottom spring plates.
• ‒ As soon as tensioner V.A.G 1752/1 is free, stop slackening off and detach tensioner.
• ‒ Detach adjustment gauge -1752/8-.
• ‒ Take suspension strut out of suspension strut holder V.A.G 1752/2.

• ‒ → Axis -C- of cap offset by 90° with respect to axis -A- of shock absorber eye; position cap on upper spring plate.

Note:

Coat O-ring with silicone grease G 000 405 A2 before fitting cap.

• ‒ → Use special tools shown to press in cap.

Explanatory notes on factory codes (PR numbers)

PR numbers are used to facilitate running gear/spring/shock absorber assignment.

The spring/shock absorber assembly installed in the vehicle can be seen from the corresponding PR number on the vehicle data sticker.

→ Example of vehicle data sticker

• ‒ - A - indicates PR no. for front axle
• ‒ - B - indicates PR no. for rear axle

The vehicle data sticker can be found in the spare wheel well and in the Service booklet.

The PR no. can be used to find the correct spring/shock absorber combination in the Parts List.

→ The PR no. for the different running gear versions can be seen from the Fig. - arrow -.

1BA = Standard running gear

1BB = Heavy-duty running gear (approx. 20 mm higher)

1BC = Special-purpose vehicles

1BD =Sports running gear (Audi S4)

RS4 = Sports running gear (RS4)

1BE = Sports running gear

1BV = Sports running gear (quattro GmbH)

1BQ = Sports running gear (South Africa)

1BT = Heavy-duty running gear (approx. 7 mm higher)

1BP = Heavy-duty running gear (trim position as for 1BA, however with limited bump travel)
