Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, strut spring compressor.
Safely elevate the vehicle using a jack and place it on jack stands.
Remove the wheel corresponding to the leaking strut.

2. Remove the Strut Assembly

Disconnect Components:
- Remove the brake line bracket attached to the strut.
- Disconnect the sway bar link from the strut.
- Remove any other components obstructing strut removal (e.g., ABS wire, if applicable).
Unbolt the Strut:
- Locate and remove the lower strut mounting bolts using the socket set.
- Proceed to the top of the strut tower under the hood; remove the retaining nuts while supporting the strut.
Extract the Strut:
- Carefully pull the strut assembly out from the wheel well.

3. Replace Strut Components

Disassemble the Strut:
- Secure the strut in a strut spring compressor to safely compress the coil spring.
- Remove the top nut and disassemble the strut from the spring.
Install New Strut:
- Attach the new strut to the existing coil spring using the spring compressor.
- Replace the top nut and secure it to manufacturer specifications.

4. Reinstall the Strut Assembly

Position the Strut:
- Insert the strut assembly back into the strut tower and secure it at the top with the retaining nuts.
Bolt the Lower Strut:
- Reattach the lower strut mounting bolts and tighten them to the specified torque value (consult the service manual).
Reconnect Components:
- Reconnect the sway bar link, brake line bracket, and any other components removed during disassembly.

5. Final Checks

Reinstall the wheel and lower the vehicle to the ground.
Perform a final torque check on all bolts and nuts.
