3	Insert suspension strut (13) into tensioning device (11).	Insert suspension strut (13) to tension as many spring coils (5) as possible.
4	mark spring (5) and clamping plates (12) relative to each other using adhesive strips.	Do not use a touch-up paint pen because the spring (5) is color coded.
5	Clamp spring (5) until spring retainer (2) is relieved.	Assembly:  Align spring retainer (2), as shown, to shock absorber (10).
6	Counterhold piston rod (8), remove nut (1) and take off spring retainer (2) as well as spring seat (4).	Do not use an impact wrench. Assembly:  Depending on the spring (5) involved, none, one or two shims (3) are fitted between the spring cup (2) and the spring seat (4). The spring (5) has an appropriate marking on the fourth coil. The last two characters define the load group and thereby the installation of the shims (3). L1 = Two shims (3) L2 = One shim (3) L3 = No shim (3)

7	Remove shock absorber (10) from spring (5).
8	Remove boot (7) and stop buffer (6).
9	Release tensioning device (11) and remove spring (5).	Assembly:  When replacing the spring (5) transfer the marking on the old spring (5) to the new spring (5). Assembly:  Make sure that the marking on the fourth coil of the spring (5) is not concealed by the tensioning device (11).
