Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, strut spring compressor
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use a jack to lift the vehicle and place it securely on jack stands.
Remove the front or rear wheel (depending on which strut is leaking) using a socket set.

3. Remove the Strut Assembly

Sub-steps:
1. Disconnect the sway bar link from the strut using the appropriate socket.
2. Remove the lower strut mount bolts, noting their orientation for reinstallation.
3. Access the upper strut mount under the hood and remove the nuts securing it to the chassis.
4. Carefully pull the strut assembly out from its position.

4. Replace the Strut

Sub-steps:
1. Use a strut spring compressor to safely compress the coil spring.
2. Remove the top mount from the old strut and attach it to the new strut.
3. Install the coil spring onto the new strut, ensuring it is seated correctly.
4. Remove the spring compressor once the strut is fully assembled.

5. Reinstall the Strut Assembly

Sub-steps:
1. Insert the new strut assembly back into its position.
2. Secure the upper mount with the nuts and lower mount with bolts, following the torque specifications from the service manual.
3. Reattach the sway bar link.

6. Reassemble the Vehicle

Reinstall the wheel and lower the vehicle back to the ground.
Torque the wheel lug nuts to the manufacturer’s specifications.
