Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather all necessary tools and safety equipment.
Tools Required: Jack, jack stands, socket set, torque wrench.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on which struts are being replaced.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel to access the strut assembly.

4. Remove the Strut Assembly

Locate the bolts securing the strut to the steering knuckle and the top strut mount.
Use the socket set to remove these bolts. Keep all hardware for reinstallation.
Carefully detach the strut assembly from the vehicle.

5. Install New Struts

Place the new strut in the same position as the old one and secure it to the steering knuckle and top mount using the original hardware.
Torque the bolts to the manufacturer’s specifications (typically around 50-60 ft-lbs for the lower bolts and 20-30 ft-lbs for the top mount).

6. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle back to the ground and use the torque wrench to tighten the lug nuts to the recommended torque specification (typically around 80-100 ft-lbs).

7. Final Check

Check the alignment if struts were replaced on the front end to ensure proper handling and tire wear.
