Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during the repair.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which struts need replacement.
Secure the vehicle on jack stands for safety.

3. Remove Strut Assembly

Front Struts:
1. Remove the wheel to access the strut assembly.
2. Detach the brake line and any electrical connectors from the strut.
3. Unbolt the strut from the steering knuckle and upper mount (refer to manufacturer torque specifications).
4. Carefully slide the strut out of its mounting position.
Rear Struts:
1. Remove the rear wheel.
2. Unbolt the lower strut mount from the trailing arm.
3. Remove any additional components obstructing strut removal (e.g., sway bar links).
4. Unbolt the upper strut mount from the vehicle body and remove the strut.

4. Install New Strut Assembly

Position the new strut into the mounting location.
Front Struts:
1. Install the strut into the upper mount and secure it with bolts (torque to manufacturer specifications).
2. Reattach the lower strut mount to the steering knuckle.
3. Reconnect the brake line and electrical connectors.
Rear Struts:
1. Install the new strut into the upper mount and secure it.
2. Reattach the lower strut mount to the trailing arm.
3. Reinstall any previously removed components, such as sway bar links.

5. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle from jack stands.
Reconnect the battery.

6. Final Inspection

Check all connections to ensure they are secure.
Verify the alignment of the wheels, as strut replacement may affect alignment.
