Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove the Wheel

Use a jack to lift the vehicle and support it on jack stands.
Remove the wheel using a lug wrench.

3. Remove the Strut Assembly

Detach the brake line and any sensors attached to the strut assembly.
Remove the bolts holding the strut to the steering knuckle using a socket set.
Unbolt the strut from the top mount in the engine bay (may require removal of additional components for access).
Carefully extract the strut assembly from the vehicle.

4. Replace Seals or Strut Assembly

If only seals are leaking, disassemble the strut and replace the seals using a seal kit.
If the strut is severely damaged or leaking, replace the entire strut assembly with a new or refurbished part.
Ensure proper lubrication of seals when reassembling.

5. Reinstall the Strut Assembly

Position the strut assembly back into place and secure it to the top mount.
Attach the strut to the steering knuckle and tighten bolts to manufacturer specifications (usually around 80-100 ft-lbs).
Reconnect the brake line and sensors.

6. Reinstall the Wheel

Place the wheel back on and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the recommended specifications (typically 100-110 ft-lbs).

7. Final Checks

Reconnect the negative battery terminal.
Check fluid levels if applicable and ensure everything is secure.
