Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues during repair.

2. Lift the Vehicle

Use a hydraulic lift or jack to raise the vehicle.
Secure with jack stands to ensure safety while working underneath.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel to access the strut assembly.

4. Remove the Strut Assembly

Disconnect any electrical connections related to the strut (if applicable).
Remove the bolts securing the strut to the hub assembly using a torque wrench.
Unbolt the strut from the upper mount under the hood, ensuring to support the strut during removal.
Carefully pull the strut assembly from the vehicle.

5. Replace or Repair the Strut

If replacing, install the new strut by reversing the removal steps.
If repairing, replace the strut seals or components as necessary, following manufacturer specifications for reassembly.
Ensure proper torque specifications for all bolts are adhered to, typically around 50-70 ft-lbs for strut mounts.

6. Reassemble Components

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually around 100-120 ft-lbs).
Reconnect the battery.
