Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, strut spring compressor, impact wrench (if available), safety goggles, gloves.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues while working.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle as required.
Secure the vehicle with jack stands to ensure stability during the repair.

3. Remove the Wheel

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

4. Remove the Strut Assembly

4.1. Detach the brake line and ABS sensor wire from the strut.
- Use a socket to unbolt any clips holding the brake line and ABS wire.
4.2. Unbolt the strut from the steering knuckle.
- Remove the bolts securing the strut to the steering knuckle using the impact wrench or socket set. Be cautious and support the knuckle as you remove the last bolt.
4.3. Unbolt the strut at the top mount.
- Open the hood and locate the strut mount under the hood. Remove the nuts securing the strut mount using the socket set.

5. Replace the Strut

5.1. Compress the coil spring.
- Using the strut spring compressor, carefully compress the coil spring on the old strut.
5.2. Remove the old strut from the spring.
- Once the spring is safely compressed, unbolt the strut from the spring perch and remove the strut.
5.3. Install the new strut.
- Place the new strut into the coil spring and secure it using the appropriate bolts.

6. Reassemble the Strut Assembly

6.1. Reinstall the strut assembly.
- Position the strut back into the vehicle, securing it at the top mount first.
6.2. Secure the strut to the steering knuckle.
- Reattach the strut to the steering knuckle and tighten the bolts to the manufacturer's torque specifications.
6.3. Reattach the brake line and ABS sensor wire.
- Ensure that all components are reattached securely.

7. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.

8. Final Checks

Once the vehicle is on the ground, recheck all bolts and connections for tightness.
