Spring, Removing And Installing, Coil Spring: Removing
-- Mark the installation direction of the coil spring, if the factory installed mark is no longer visible. Refer to Figure.
-- Remove the rear wheel. Refer to WHEELS AND TIRES .
-- Release the retainers in direction of -arrow- and remove the retaining pin -1-.
-- Remove the wind deflector -2- from the transverse link.
Right Side of Vehicle:
-- Remove the right underbody trim panel. Refer to OVERVIEW - UNDERBODY TRIM PANELS .
Left Side of Vehicle:
-- If installed, remove the bolts -arrows- and remove the drive axle heat shield -1-.
-- Final drive 0D3 "quattro sport" : remove the bolts -arrows-, and remove the drive axle heat shield -A- from the rear final drive.
-- Remove the bolts -arrows- on the inner CV joint, and tie up the drive axle toward the front.
-- Place the Spring Tensioning System - Spreader Device:VAS 6274/8 and the Supplement Set - Support Plate for Spreader:VAS 6274/13 , between the front upper transverse link -1- and the longitudinal member as shown, and pretension slightly.
-- Press the locking plate -2- outward in direction of -arrow A- (open).
-- Insert the Supplement Set - Thrust Plate with Securing Plate:VAS 6274/12-2 as shown from the outside into the coil spring -1-.
-- Insert the Supplement Set - 89mm Plunger:VAS 6274/12-7 with the Spring Tensioning System - T-Bar:VAS 6274/5 into the thrust plate and turn 90° until the line marking -3- on the thrust plate is flush with the line marking -4- on the plunger.
-- Pull the plunger downward into the thrust plate and secure with the locking plate -arrow B- (close).
-- Remove the Spring Tensioning System - T-Bar:VAS 6274/5 .
There is a risk of damaging the spindle due to missing or incorrect grease.
- Coat the front area of the Spring Tensioning System - Spindle:VAS 6274/3 -item 2- lightly with the accompanying grease -1- before removal and installation of each spring.
-- Insert the Supplement Set - Thrust Plate with Swivel Bearing:VAS 6274/12-1 as shown from the outside into the coil spring -arrow-.
-- Lightly lubricate the Spring Tensioning System - Spindle:VAS 6274/3 in the front area and screw loosely into the Supplement Set - 89mm Plunger:VAS 6274/12-7 using the Spring Tensioning System - Socket:VAS 6274/6 .
Risk of accident!
- The coil spring may only be tensioned or released if the locking device brackets -2 and 5- are connected to each other through both bolts -3-.
-- Turn the Supplement Set - Thrust Plate with Securing Plate:VAS 6274/12-2 all the way upward and turn the Supplement Set - Thrust Plate with Swivel Bearing:VAS 6274/12-1 all the way downward.
-- Tighten the locking device brackets -2 and 5- to both thrust plates -arrows-.
- The locking device brackets face forward.
Depending on the type of suspension, the attachment point of the locking device brackets to the thrust plates can be different.
-- Screw in the locking device bracket bolts -3- for both thrust plates to the backing plate -4- by hand.
-- Lightly tension the thrust plates using the Spring Tensioning System - Spindle:VAS 6274/3 .
-- Check if the coil spring -1- is seated correctly in the thrust plates.
There is a risk of damaging the threads.
- The Spring Tensioning System - Spindle:VAS 6274/3 must not be tensioned or released using an impact wrench.
- Always turn the spindle using a commercially available ratchet.
There is a risk of damaging the transverse link.
- The tensioner thrust plates must not contact the transverse link when tensioning the coil springs. Turn the thrust plates if necessary.
-- Tension the coil spring with the Spring Tensioning System - Socket:VAS 6274/6 by counterholding with the Spring Tensioning System - Counterhold Tool:VAS 6274/7 .
Risk of injury due to uneven tensioning of the coil springs.
- The coil spring tension may only be released in the Spring Tensioning System - Hydraulic Tensioner:VAS 6274/9 .
-- Tension the coil spring until it can be removed.
-- If necessary for subsequent work, remove the Spring Tensioning System - Spreader Device:VAS 6274/8 with the Supplement Set - Support Plate for Spreader:VAS 6274/13 .
Release the coil spring tension in the Spring Tensioning System - Hydraulic Tensioner:VAS 6274/9 .
Loose threaded connections increase the risk of injury.
- Make sure the nuts -arrows- are secure and tighten if necessary, before using the Spring Tensioning System - Hydraulic Tensioner:VAS 6274/9 .
-- Mount the Supplement Set - Spring Support:VAS 6274/12-3 on the Spring Tensioning System - Hydraulic Tensioner:VAS 6274/9 .
-- Place the pretensioned coil spring -2- with the bottom side on the spring support.
- The end of the spring coil must rest on the spring support stop -arrow-.
-- Guide the hydraulic tensioner plunger -1- out all the way to the coil spring and do not tighten.
-- Mark the plunger position -1- on the Spring Tensioning System - Hydraulic Tensioner:VAS 6274/9 -arrow A- with a waterproof felt-tip pen, for example.
-- Mark the position of the anti-twist mechanism -2- on the coil spring -3- -arrow B- with a waterproof felt-tip pen, for example.
The marks are needed when tightening for installation.
There is a risk of damaging the threads.
- The Spring Tensioning System - Spindle:VAS 6274/3 must not be tensioned or released using an impact wrench.
- Always turn the spindle using a commercially available ratchet.
-- Release the coil spring tension completely using the Spring Tensioning System - Socket:VAS 6274/6 with the hydraulic tensioner.
-- After the coil spring -1- tension is released, remove the Spring Tensioning System - Spindle:VAS 6274/3 .
-- Remove the locking device bolts -2- and remove with the backing plate -3-.
-- Remove the Supplement Set - Thrust Plate with Swivel Bearing:VAS 6274/12-1 .
-- Press the locking plate -1- outward in direction of -arrow B- (open).
-- Remove the Supplement Set - 89mm Plunger:VAS 6274/12-7 with the Spring Tensioning System - T-Bar:VAS 6274/5 from the Supplement Set - Thrust Plate with Securing Plate:VAS 6274/12-2 .
-- Remove the thrust plate from the coil spring -2-.
Ignore -item 3, 4 and arrow A-.
If the opposite coil spring in the vehicle should also be removed, then the installation position and attachment point of the locking device bracket to the thrust plates must be marked for later installation.
If the coil spring is replaced, then the applied mark must be transferred to the new coil spring.
