3. Inspect Components: Check the surrounding suspension components (struts, control arms, bushings) for wear or damage before proceeding.
4. Install New Spring: Position the Lesjofors 4008494 onto the mounting points. Align it precisely with the retaining clips and secure it using the original bolts.
5. Torque Specifications: Tighten all bolts to the manufacturer’s recommended torque settings (typically 80–100 Nm, depending on bolt size).
6. Reassemble: Reinstall any removed components such as strut housings or control arm brackets.
7. Test Ride: After installation, perform a short test drive to confirm proper operation and check for any abnormal noises or handling issues.

Maintenance Tips

While the Lesjofors 4008494 Suspension Spring is built for longevity, regular maintenance can further extend its life:

• Periodic Inspection: Check for visible signs of wear, such as dents or cracks in the spring coils.
• Lubrication: Apply a light coat of high‑temperature grease to the mounting points to prevent corrosion.
• Alignment Checks: Ensure that wheel alignment remains within manufacturer specifications after any suspension work.
• Load Management: Avoid overloading the vehicle beyond its rated capacity, as excessive weight can accelerate spring fatigue.
