FAQs

Do I need to replace these in pairs?

Yes, it is highly recommended to replace front shock absorbers in pairs to maintain balanced handling and even tire wear.

Is this compatible with my sport suspension?

The SACHS 317 559 is engineered to be compatible with both standard and sports suspension configurations on supported Mercedes-Benz models.

What tools are required for installation?

You will need a professional-grade spring compressor, a torque wrench, and standard metric socket sets. A strut nut socket is also recommended.

Should I get an alignment after installation?

Yes, any work involving the removal and installation of suspension struts should be followed by a professional four-wheel alignment.

How long do these shock absorbers typically last?

While lifespan depends on driving habits and road conditions, these units are built to OE standards and typically provide optimal performance for 50,000 to 80,000 miles.

Troubleshooting

Increased noise or knocking sound over bumps

Check if the top mounting nut is tightened to torque specifications and inspect the stabilizer bar links for wear.

Vehicle feels bouncy or lacks stability

Ensure that the shock was correctly bled before installation and verify that no air pockets remain in the twin-tube system.

Visible oil residue on the shock body

A light film of oil can be normal, but dripping oil indicates a seal failure; replace the shock if leakage is excessive.

Pros and Cons

Pros

  • Significantly improves vehicle cornering stability
  • Gas-pressure technology provides consistent damping across temperature changes
  • Robust construction with advanced corrosion protection
  • Compatible with both standard and sports suspension setups

Cons

  • Requires professional-grade tools like a spring compressor for installation
  • Limited to specific Mercedes-Benz vehicle platforms
  • Professional alignment recommended immediately after installation

Setup, Compatibility & Care

Before starting installation, verify that your vehicle's specific chassis number matches the supported OE part numbers for the SACHS 317 559. Always replace shock absorbers in pairs (left and right) to ensure balanced handling. During installation, do not use an impact wrench on the top piston rod nut, as this can damage the internal valves. Regarding care, periodic visual inspections of the dust boot and bump stop are recommended; if the dust boot is torn, it should be replaced immediately to prevent grit from scoring the shock shaft, which can lead to premature seal failure and fluid leaks.
