Disassembly and assembly instructions: Assembly

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.

Slide the protective tube/additional spring assembly on the piston rod.
Slide the stop plate No. 7 as far is it will go into the correct position on the piston rod.
Push the coil spring onto the vibration damper so that the end of the coil spring rests against the stop of the spring plate.

Place ring No. 5 with the spring plate in the correct position (observe three recesses) on the spring strut mount and jointly fit them on the piston rod/coil spring. Screw new fastening nut onto the piston rod until approx. 1 to 2 threads are visible above the fastening nut.

Position the spring strut mount for installation (correctly position spring strut mount with respect to the damper). The mounts for the right and left sides are identical parts.
The mount is positioned correctly if the fastening bolt in the downward-angled part of the spring strut mount is aligned with the retaining plate on the damper tube.

Tighten the fastening nut once the mount has been correctly positioned and the coil spring lies properly against the stop.

Use a socket wrench insert open on one side -e.g. Hazet- to tighten the fastening nut on the spring strut mount.

This ensures that exactly the prescribed tightening torque of 60 Nm (44 ftlb.) can be observed. Furthermore, it is possible to counter at the piston rod with an angled 7 mm hexagon socket key at the same time.
