Assembling Front Spring Strut

WARNING: This page is about a different car, the 2024 Porsche 911, 2023 Porsche 911, and 2022 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.

For vehicles without front axle lift system: Fit lower spring plate -1- on vibration damper.

Control dimension from lower edge of vibration damper to lower edge of actuator
- Lower spring plate must not be fitted!
- Pressure line connection must be flush with the vibration damper position plate > Position of actuator .
- Press on the actuator until the control dimension -s- of 148.6 mm +/- 1 mm is reached.
Information

Do not fit the stop cap at an angle!

Positioning the lower spring plate
- Position lower spring plate so that the end of the coil spring is positioned clockwise at an angle -X- to the pressure line.
- Align lower spring contact bracket with the pressure line (front axle lift system) at an angle of 45°.

For vehicles with front axle lift system: Press actuator -2- onto the vibration damper -1- .

Information

Explanation of the colored dots on the coil spring:
- Colored dots -1- provide information about the allocation to the vehicle variant and equipment (see Porsche Spare Parts Information!
- Colored dot -2- indicates the tolerance group to determine whether a tolerance compensation shim must be fitted.
Colored dot -2- yellow: no tolerance compensation shim should be installed.

NOTE: If the tolerance is borderline, a tolerance compensation shim can still be installed during production. Do not install a tolerance compensation shim when installing a replacement spring with a yellow dot !

Colored dot -2- blue : a tolerance compensation shim can be installed on the production side or not!
- Only when installing a replacement spring with a blue colored dot, also install a tolerance compensation shim!

WARNING:
Preloaded or pressurized components
- Risk of squashing or bruising
  - Do not reach into the danger area.
  - Relieve tension on components before starting work.
  - Secure components to prevent them from loosening suddenly.
Pre-tension the spring strut until the tension on the piston rod is relieved.
Tighten hexagon nut -1- using a commercially available open socket-wrench insert (a/f 21 mm) for example Hazet, number 2593 .
Counter at the hexagon nut -2- on the piston rod.

> Tightening torque 70 Nm (52 ftlb.)
Seal hexagon nut -1- and projecting part of the piston rod -2- with Pfinder AP14/4 corrosion protection wax.
