Solution

1. Preparation

Gather tools and parts needed for the strut replacement.
Park the vehicle on a level surface and engage the parking brake.
Lift the vehicle using a hydraulic jack and support it with jack stands.

2. Remove the Wheel

Using a lug wrench, loosen the lug nuts on the wheel where the strut is being replaced.
Remove the lug nuts completely and take off the wheel.

3. Disconnect the Strut

Remove the lower strut bolt using a socket and ratchet.
For the upper strut mount, access it from under the hood. Remove the nuts securing the strut to the mount, ensuring to support the strut with one hand while removing the last nut.

4. Inspect and Clean

Inspect the strut mount for wear and replace if necessary.
Clean any debris from the mounting surfaces before installing the new strut.

5. Install New Strut

Position the new strut into place and secure it to the upper mount with the nuts. Torque to manufacturer specifications (typically around 15-20 ft-lbs).
Reinstall the lower strut bolt and torque to specifications (typically around 85-100 ft-lbs).

6. Reattach Wheel and Lower the Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and use the lug wrench to tighten the lug nuts to the specified torque (typically around 75-85 ft-lbs).
