Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which strut is leaking.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

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

4. Disassemble the Strut

Top Mount Removal:
- Locate the top strut mount under the hood.
- Remove any covers if necessary.
- Use a socket wrench to remove the nuts securing the strut to the top mount.
Lower Mount Removal:
- Use a socket set to remove the bolts securing the strut to the lower control arm.
- Carefully pull the strut assembly out of its mounting position.

5. Replace the Strut

Install New Strut:
- Position the new strut assembly into the strut tower and lower control arm.
- Secure it by tightening the lower mounting bolts to the manufacturer's specified torque (typically around 70-90 ft-lbs, but check your service manual).
- Reattach the top mount nuts and tighten them to the specified torque (usually around 15-20 ft-lbs).

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off jack stands and then fully tighten the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).
Reconnect the battery.
