How to Replace Car Shock Absorbers Yourself? Step-by-Step Guide

Introduction

Replacing shock absorbers in your car is one of those tasks that many drivers can perform themselves, saving both time and money. In this article, you will find a detailed step-by-step guide on how to replace shock absorbers in your vehicle, what tools are needed, and which techniques to use to ensure the process runs smoothly and safely.

Preparing for Shock Absorber Replacement

Tools Needed for Shock Absorber Replacement:

• Set of socket and open-end wrenches
• Torque wrench
• Car jack
• Jack stands
• Pliers
• Penetrating oil (e.g., WD-40)
• New shock absorbers
• Set of bolts and nuts (if not included with new shock absorbers)
• Protective gloves

Step 1: Preparing the Car

1. Park the car on a level, stable surface. Make sure the car is on the handbrake.
2. Loosen the wheel nuts. Use a wheel wrench to slightly loosen the nuts on the wheel where you will be replacing the shock absorber.

Step 2: Lifting the Car

1. Use the car jack to lift the car. Raise the vehicle high enough so that the wheel is completely off the ground.
2. Place jack stands under the appropriate support points of the car. Ensure the car is stable and safe.

Step 3: Removing the Wheel

1. Completely unscrew the wheel nuts and remove the wheel, setting it aside.

Step 4: Removing the Old Shock Absorber

1. Locate the upper and lower mounts of the shock absorber. These are usually bolts and nuts that you need to unscrew.
2. Spray the bolts with penetrating oil (e.g., WD-40) to make them easier to unscrew.
3. Use appropriate wrenches to unscrew the bolts of the upper mount of the shock absorber. Then unscrew the lower mount.
4. Remove the old shock absorber from the car’s suspension.

Step 5: Installing the New Shock Absorber

1. Prepare the new shock absorber for installation. Make sure you have all the necessary components (bolts, nuts, washers).
2. Place the new shock absorber in position of the old one, starting with the lower mount. Hand-tighten the bolts to keep the shock absorber in place but do not fully tighten them yet.
3. Tighten the upper mount of the shock absorber, also only hand-tighten initially.
4. Use a torque wrench to tighten the bolts according to the torque specifications recommended by the manufacturer. Typically, this is about 50-60 Nm for the upper mount and 80-100 Nm for the lower mount, but check the specifications for your car.

Step 6: Reinstalling the Wheel

1. Reattach the wheel to the hub and hand-tighten the nuts to stabilize it.
2. Lower the car using the jack until the wheel touches the ground, but do not fully rest the car’s weight on the wheel yet.
3. Tighten the wheel nuts thoroughly using a torque wrench according to the recommended torque specification (usually about 100-120 Nm).

Step 7: Checking and Completing the Job

1. Fully lower the car and remove the jack and jack stands.
2. Double-check all connections, ensuring all bolts are properly tightened.
3. Take a short test drive to ensure the new shock absorbers are working correctly and there are no unusual sounds.

Conclusion

Replacing shock absorbers in your car yourself is a task that can be done with the right tools and instructions. It is important to carefully follow procedures and manufacturer recommendations to ensure the safety and effectiveness of the new shock absorbers. Regular inspection and replacement of shock absorbers is an investment in driving comfort and safety, helping to avoid larger problems and costly repairs in the future.

Remember to regularly check the condition of your suspension and other vehicle components to ensure a safe and comfortable ride for you and your passengers.
