Disassembly

Caution:
Danger of injury due to spring tensioning!
^ If necessary, tension the coil spring (depending on the spring preload) with the spring clamp until the piston rod is relieved!
^ Never use an impact bolter to loosen or tighten the fastening nut!
^ Use commercially available changeover ratchet!

1. If necessary, tension the coil spring (depending on the spring preload) with the spring clamp until the piston rod is relieved.
2. To undo the connection - piston rod to spring strut mount - counter at the piston rod with countering tool Sonderwerkzeug 9630 or an open-ended wrench (7 mm).
3. Remove all parts from the piston rod.

Preliminary work and notes on assembly





^ If the vibration damper is to be replaced, set the height adjusting nut -1- to the same position as on the old vibration damper (transfer the actual dimension A to the new vibration damper). A hook wrench insert, special tool 9647 is required for this purpose.
^ Tightening torque of the lock nuts -2 + 3- = 50 Nm (37 ft. lbs.)!
^ The stabilizer mating bearing (mounting saddle) -4- need not be adjusted for street use.





^ The hook wrench insert Sonderwerkzeug 9647 is required to change the vehicle height and to adjust the stabilizer mating bearing on the front and rear axle. The special tool is used together with a torque wrench to tighten the lock nuts (slotted nuts) on the spring struts.

Assembly





1. Slide the additional spring -9-, washer -8- and stop plate -7- (stop plate in correct position) as far as they will go on the piston rod.
2. Place coil spring -6- in the correct position, tighter winding facing down, onto the vibration damper.





Note:
^ The coil spring -6- is fitted as standard with a protective sheath -arrows- at the top and bottom on vehicles as of model '02 (2).
^ On vehicles of model '01 (1), mount (fit) the protective sheath at the top and bottom -arrows- in the area of the contact points of both spring ends.

3. Fit spring plate (spring retainer), support ring (rubber washer) and spring strut mount onto the coil spring.

Note:
^ If the support ring (rubber washer) is not yet available, fit the rubber washer on vehicles of model '01 (1)!

4. Place stop plate in the correct position on the spring strut mount.

Note:
^ Replace nut for fastening the piston rod on the spring strut mount!

5. Screw new fastening nut onto the piston rod until approximately 1 to 2 threads are visible above the fastening nut.





Note:
^ The spring strut mount for the right and left sides are identical parts!
^ The spring strut mount is positioned correctly if one of the 3 fastening pins is aligned with the stabilizer mounting saddle!

6. Position the spring strut mount for installation (correctly position spring strut mount with respect to the damper).
7. Once the mount has been positioned correctly, tighten the fastening nut. Tightening torque 60 Nm (44 ft. lbs.).

Note:
^ Never use an impact bolter to tighten the fastening nut!

8. When tightening the fastening nut, hold at the piston rod using a countering tool Sonderwerkzeug 9630 or a 7 mm open-ended wrench.
