2. Remove Old Shock: Detach the upper and lower mounting bolts, then carefully extract the existing shock absorber.
3. Position New Shock: Align the new unit with the mounting points. Ensure that the gas cylinder is oriented correctly to avoid fluid leakage.
4. Secure Mounts: Tighten the upper and lower bolts to the manufacturer’s torque specifications. Use a calibrated torque wrench for accuracy.
5. Reassemble: Reinstall the wheels, reconnect the battery, and lower the vehicle.
6. Test Drive: Conduct a short drive to verify smooth operation. Check for any abnormal noises or vibrations.

Maintenance Tips

While the Sachs 313446 Vibration Damping is designed for longevity, routine checks can extend its life:

• Visual Inspection: Periodically examine the shock housing for cracks, dents, or fluid leaks.
• Seal Condition: Inspect rubber seals for signs of wear or hardening. Replace if necessary.
• Fluid Level: Although gas‑charged, some models may have a small amount of hydraulic fluid. Ensure it remains within the recommended range.
• Alignment Checks: After major repairs or impacts, verify that the suspension geometry remains within specifications.
