  • Gather All Tools and Parts: Organize your workspace and ensure all necessary tools and parts are within reach.
  • Safety First: Wear safety gear and work on a flat, stable surface with proper lighting.

Step-by-Step Lowering Process

  1. Prepare the Vehicle: Park your Volvo S80 on a flat, level surface. Engage the parking brake and place wheel chocks behind the rear wheels to prevent any movement.
  2. Lift the Vehicle: Using a hydraulic floor jack, carefully raise the front or rear of the vehicle, depending on which suspension you plan to work on first. Always secure the car on jack stands placed under the manufacturer-recommended lifting points for stability.
  3. Remove the Wheels: Using your lug wrench or impact gun, loosen and remove the wheel lug nuts, then take off the wheels to expose the suspension components.
  4. Apply Penetrating Oil: Spray penetrating oil on all suspension bolts and fasteners to ease removal. Allow several minutes for the oil to work, especially if bolts appear rusty or corroded.
  5. Detach Suspension Components: Depending on whether you are replacing springs or coilovers, carefully unbolt the shock absorbers or struts. If you're working with strut assemblies, use a spring compressor to safely compress and remove the springs. Take care to note the orientation and setup of all components for a smooth reinstallation.
  6. Install Lowering Kit: Position the OEM-compatible lowering springs or coilovers into place according to the manufacturer's instructions. If using coilovers, adjust the preload and ride height settings as desired. When installing springs, ensure they are seated properly to avoid noise or premature wear.
  7. Reassemble and Torque Bolts: Reattach all suspension components, ensuring that bolts are tightened with a torque wrench to Volvo’s specified torque settings. Proper torque prevents loosening and ensures suspension integrity.
  8. Reinstall the Wheels: Mount the wheels back onto the hubs and hand-tighten lug nuts initially. Lower the vehicle slightly to allow the tires to contact the ground, then torque the lug nuts in a star pattern to the manufacturer’s specification.
  9. Lower the Vehicle: Remove the jack stands and carefully lower the car completely to the ground. Double-check that all tools and equipment are removed from underneath the vehicle.
  10. Repeat for Remaining Corners: If you started with the front suspension, repeat the process for the rear, or vice versa.
  11. Test Drive: Conduct a cautious test drive to evaluate the handling and listen for unusual noises. Pay attention to ride comfort and responsiveness.
  12. Professional Wheel Alignment: After lowering, it is crucial to have a professional alignment performed. Lowering alters suspension geometry, affecting camber, toe, and caster angles, which can lead to uneven tire wear and compromised handling if not corrected.
