Installation Overview

Installing the Lesjofors 4008493 Suspension Spring is a straightforward process that aligns with OEM procedures. The spring fits directly into the existing mounting brackets and retains the original coil housing geometry, ensuring compatibility without modification.

1. Remove Existing Coil: Detach the current front suspension spring by loosening the mounting bolts and carefully extracting the coil from the housing.
2. Position the New Spring: Align the Lesjofors 4008493 with the mounting points, ensuring that the coil’s orientation matches the original setup.
3. Secure Mounting Bolts: Tighten all bolts to the manufacturer’s specified torque settings to guarantee proper preload and prevent slippage.
4. Reassemble Suspension: Reinstall any removed components such as shock absorbers or sway bars, then perform a final check for alignment and balance.

Quality Assurance & Compliance

The Lesjofors 4008493 Suspension Spring adheres to stringent quality standards set by automotive manufacturers. Each spring undergoes:

• Dimensional Inspection: Precision measurements ensure that the spring’s length, diameter, and coil pitch meet OEM tolerances.
• Material Testing: Metallurgical analysis verifies alloy composition and heat‑treatment integrity.
• Load & Fatigue Testing: Simulated compression cycles confirm the spring’s ability to withstand long‑term use without failure.

Maintenance Tips

While the Lesjofors 4008493 Suspension Spring is designed for longevity, routine checks can further extend its life:

• Visual Inspection: Periodically examine the spring for signs of corrosion or deformation.
• Torque Verification: Re‑tighten mounting bolts at recommended intervals to maintain preload.
• Alignment Checks: Ensure that wheel alignment remains within specifications after installation, as misalignment can accelerate wear.
