⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a vehicle to prevent accidents.
•Allow the vehicle to cool down before working on suspension components that may have been heated during driving.

Symptoms

•Excessive bouncing over bumps
•Poor handling and stability
•Increased body roll during turns
•Uneven tire wear
•Loud clunking or knocking noises from the suspension

Diagnostic Steps

1
Inspect the struts visually for any signs of leakage or physical damage.
2
Perform a bounce test by pushing down on each corner of the vehicle to assess strut response.
3
Check for proper tire pressure and inspect tires for uneven wear patterns.
4
Examine other suspension components such as control arms and bushings for wear and damage.
5
Use a level to check if the vehicle is sitting unevenly, indicating potential issues with the suspension.

Solution

1. Preparation

Gather tools and parts needed for the strut replacement.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheels.
Store the lug nuts in a safe place for reinstallation.

4. Remove Old Strut Assembly

Locate the strut assembly; remove the bolts connecting it to the steering knuckle.
Disconnect any brake lines or sensors attached to the strut.
Remove the top mounting bolts of the strut from the engine bay.
Carefully pull the strut assembly out of the wheel well.

5. Install New Strut Assembly

Position the new strut into the wheel well and secure the top mount with bolts.
Reattach the strut to the steering knuckle, tightening the bolts to the manufacturer’s specified torque values.
Reconnect any brake lines or sensors that were detached.

6. Reinstall Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.

7. Final Checks

Reconnect the battery.
Inspect the new struts for any installation issues.
