Step-by-Step Instructions for Coil Spring Replacement

To replace the rear coil springs, follow these steps:

1. Prepare the Vehicle:

   Ensure the vehicle is parked on a level surface, activate the parking brake, and assess that it's safe to lift the vehicle.

2. Lift the Car:

   Using a jack, hoist the back of the car and securely position it on jack stands. Confirm its stability before proceeding.

3. Take Off the Wheels:

   Loosen the lug nuts on the rear wheels and remove them, providing access to the suspension parts.

4. Detach the Shock Absorber:

   Identify and remove the top and bottom bolts of the shock absorber using the appropriate socket. The shock absorber should now hang freely.

5. Release Tension of the Coil Springs:

   Attach coil spring compressors to the springs and compress them until no tension remains.

6. Remove the Coil Springs:

   With the tension released, carefully take the coil spring out of its seating. Ensure the spring does not escape suddenly.

7. Install New Coil Springs:

   Position the new coil springs into the suspension seats, ensuring they align correctly.

8. Remove Coil Spring Compressors:

   Gently detach the coil spring compressors, allowing the springs to expand naturally and settle into position.

9. Reattach the Shock Absorber:

   Reinstall the shock absorber by tightening the top and bottom bolts securely.

10. Put the Wheels Back On:

    Reattach the wheels and hand-tighten the lug nuts. Once the vehicle is on the ground, finish tightening them.

11. Lower the Vehicle:

    Carefully remove the jack stands and lower the car back to the ground, ensuring everything is properly secured.

12. Inspect Your Work:

    Before driving, take a moment to check that all bolts are tight and everything appears in order.

Safety Measures to Consider

When undertaking this task, ensure to:

• Wear safety glasses and gloves for protection.
• Work in a well-ventilated environment.
• Ensure the vehicle is stable before working beneath it.
• Handle coil spring compressors with care as they hold significant tension.

Signs You Should Replace Your Coil Springs

Indicators that your coil springs may require replacement include:

• Uneven height on either side of the vehicle.
• Clunking sounds from the rear when driving over bumps.
• A harsh or bouncy ride quality.

By adhering to these guidelines and implementing safety precautions, replacing the rear coil springs on your Audi A4 B6 can be a manageable and rewarding task.
