Assembling Rear Spring Strut

Information 

• Observe allocation of compensating plate according to the coil spring tolerance range. 
• Coil springs are only available in pairs (as a set). 

1. Clamp the spring strut at a suitable place in the vice (use jaw liners).
2. When replacing the vibration damper, set the spring preload dimension (height adjustment dimension) from the old damper on the new damper.
3. Place components on the piston rod and fit them on the spring strut.
   1. 3.1. Place pre-tensioned coil spring at the correct position on the vibration damper.
   2. 3.2. Slide the bellows/additional spring assembly onto the piston rod.
   3. 3.3. Fit washer.
   4. 3.4. Fit the spring-strut mount -2-  (supporting mount -2-  , compensating part -3-  and spring plate -4-  assembled at the correct position) on the piston rod.

      Place the lug on the spring-strut mount in the groove on the piston rod (twist lock of piston rod opposite the supporting mount).

5. Align (position) the spring-strut mount with respect to the vibration damper. -Lug-  of spring-strut mount must line up with the middle fork of the lower vibration damper.

6. Tighten lock nut to 32 Nm (24 ftlb.). Counter at the bolts (M8) on the spring-strut mount at the same time.

   There is no need to counter at the piston rod because there is a strong grip between the spring-strut mount and piston rod.
