Solution

1. Preparation

Gather all necessary tools and parts. Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Tools Required: Socket set, jack and jack stands, torque wrench, strut spring compressor (if replacing struts).
Safety Warnings: Always wear safety glasses and gloves; ensure the vehicle is securely supported on jack stands.

2. Remove the Wheel

Loosen the lug nuts on the wheel where struts are to be inspected.
Lift the vehicle with a jack and securely place jack stands under the vehicle.
Remove the lug nuts completely and take off the wheel.

3. Remove the Strut Assembly

Disconnect any components attached to the strut, such as brake lines or sway bar links.
Remove the bolts securing the strut to the steering knuckle and the upper strut mount.
Carefully remove the strut assembly from the vehicle.

4. Inspect and Replace (if necessary)

Inspect the strut for signs of damage, leakage, or wear. If found, proceed to replace the strut.
Compress the coil spring using a strut spring compressor if reusing the spring.
Install the new strut, ensuring the upper mount is properly seated and tightened to the manufacturer’s torque specifications.

5. Reassemble and Lower Vehicle

Reattach the strut assembly to the steering knuckle and secure with bolts.
Reconnect any components that were disconnected.
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.
Once the vehicle is lowered, torque the lug nuts to the manufacturer’s specifications.
