Removing Coil Spring

WARNING: This page is about a different variant/trim than selected.

WARNING: Preloaded or pressurised components

Risk of squashing or bruising
→ Do not reach into the danger area.

→ Relieve the tension on components before starting work.

→ Secure components to prevent them from loosening suddenly.

Information

If the coil spring is replaced: Always replace coil springs in pairs only.
Due to the settling behavior and indents, use new spring plates to replace the coil springs.

Information

Do not press coil springs together onto the block.
Do not damage the surface of the coil springs (corrosion protection).
Do not use solvents to clean the coil springs.

Information

To remove/install the coil spring, use the > VAS 6907 - spring tensioning system and > VAS 6274/12 - supplement set for spring tensioning system .

Supplement set VAS 6274/12

1	Tool case 6274/12
2	Pressure plate with latch = 6274/12-2
3	Pressure plate with pivot bearing = 6274/12-1
4	Spring support == 6274/' 2-3
5	69-mm piston - 6274/12-6
6	89-mm piston == 6274/12-7
7	Spreader device - 6274/12-4
8	Support plate for spreader device == 6274/12-5

Information

Inserting the spreader device prevents the axle from moving upwards when tensioning the coil spring and this makes it easier to install.

Always remove the spreader device from the vehicle after installing the coil spring.

Spreader device VAS 6274/12-4 -1- must be inserted between the upper trailing arm and body when the coil spring is installed.

Fitting spreader device
1. 1.1 Adjust the upper part of the spreader device for the respective vehicle side:
  - Left side of vehicle: "R" must be visible.
  - Right side of vehicle: "L" must be visible.
2. 1.2 Adjust the height of the spreader device at the hexagon -2- until it is fitted securely.

Insert spring compressor.

Spring compressor

2.1 Insert pressure plate with pivot bearing VAS 6274/12-1 -1- at the bottom of the coil spring.
2.2 Insert pressure plate with latch VAS 6274/12-2 -2- at the top of the coil spring.
2.3 Screw both pressure plates up/down as far as required until they have at least 3 windings enclosed. Position pressure plates so that they are not touching the trailing arm.
2.4 Insert piston VAS 6274/12-7 -3- with T-handle wrench VAS 6907/6 into the pressure plate with latch -2- .

2.5 Press securing lever on pressure plate with latch in -Arrow direction- to secure the piston.
