Figure 3
– Carefully mount the lift unit on the housing of the new shock absorber. Push the lift
unit up to the collar on the damper housing (end stop). Align the connection of the
lift unit with the holes in the bottom of the housing. Figure 4 -Arrow and line- Do
not use force during assembly. Never hit the upper edge of the lift unit (gasket) with
a hammer.

Figure 4
– Remove the adjustment wheel for the rebound adjustment from the new damper
unit Figure 4 -1- and the fastening nut  Figure 4 -2-of the damper housing. Do
not completely remove the grub screw  Figure 4 -3-of the adjusting wheel. Only
loosen it. Otherwise, it may get lost!

Figure 5
– Insert the spring package consisting of the helper spring, intermediate ring and
main spring into the damper unit as shown in the picture. The spring package is
always mounted with the helper spring at the top (on the upper spring plate).

Figure 6
– All four components must be installed in the order shown! If necessary, the
arrangement must be corrected! The grooves in the 4 mm/ 0.157 in thick packer
 Figure 6 -1- must point downwards (in the direction of the rebound adjustment).

Figure 7
– Mount the strut housing. Make sure that the white plastic disc in the lift unit 
Figure 7 -1- is positioned almost centrally. Otherwise, it may become damaged
during assembly! To assemble, set up the damper unit with the piston rod pointing
upwards and assemble the housing from above!

Figure 8
– Push the housing onto the damper unit until the thread of the piston rod protrudes
approx. 10 mm/ 0.394 in  Figure 8 -1- from the housing. To check that it is
correctly positioned, apply slight pressure to the housing and turn the piston rod
by approx. 180° left/right with a suitable open-end wrench. It is possible that the
piston rod has not yet snapped into place in the seat of the housing.

Figure 12
– Place the support bearing over the elongated holes  Figure 12 -1- in the dome
into the center position (picture is different). Fasten the support bearings to the
dome with three new collar nuts. Collar nut: Tightening torque 33 Nm (24.3
ftlb.)

Figure 13
– Roughly set the wheel heights for wheel alignment. On the front axle, the height
from the upper edge of the wheel carrier to the lower edge of the lower spring plate
is set at 62 mm/ 2.44 in Figure 13. If the chassis variant is installed without
a lift system, this measurement is 55 mm/ 2.165 in . Finally, reconnect the lift
system and screw the retaining bracket on tight.
