Solution

1. Preparation

Gather all tools and parts required for the repair.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the vehicle's battery to prevent any electrical issues during the repair.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which strut is leaking.
Secure the vehicle with jack stands to ensure stability while working.

3. Remove Wheel

Using a lug wrench, remove the lug nuts and take off the wheel to access the strut assembly.
Store the lug nuts safely for reinstallation.

4. Remove the Strut Assembly

Disconnect any brake line brackets or sensors attached to the strut.
Unbolt the strut from the lower control arm using the appropriate socket size.
Remove the top strut mount nuts located under the hood or in the trunk (depending on whether it's a front or rear strut).
Carefully remove the strut assembly from the vehicle.

5. Replace the Strut

Install the new strut assembly into the vehicle.
Secure the top strut mount nuts and torque them to the manufacturer’s specifications (typically around 15-20 ft-lbs).
Attach the lower end of the strut to the control arm and torque the bolts according to specifications (usually around 50-60 ft-lbs).
Reattach any brake lines or sensors that were disconnected.

6. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground using the hydraulic jack.
Once on the ground, torque the lug nuts to the manufacturer’s specifications (typically around 100-110 ft-lbs).

7. Final Checks

Reconnect the battery and check for any warning lights on the dashboard.
Perform a basic inspection to ensure everything is secure and properly installed.
