Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, strut spring compressor, penetrating oil, safety glasses, gloves.
Raise the vehicle using a jack and secure it with jack stands. Ensure the vehicle is on a level surface.
Remove the rear wheels using the lug wrench.

2. Remove Strut Assembly

Access the top strut bolts:
- Open the hood and locate the top strut mount. Remove any engine covers if necessary.
Remove the top strut nuts:
- Use a socket to remove the nuts securing the strut to the mount. Keep track of the order and placement of washers.
Disconnect the sway bar link:
- Use a socket to remove the bolt securing the sway bar link to the strut.
Unbolt the lower strut bracket:
- Locate the bolts on the lower strut mount and remove them using a socket.
Remove the strut:
- Carefully pull the strut out from its mount and set it aside.

3. Replace Strut Assembly

Compress the coil spring:
- Use a strut spring compressor to safely compress the spring on the old strut. Follow the spring compressor instructions for safety.
Remove the old strut from the spring:
- Once the spring is compressed, remove the top nut to release the strut from the spring.
Install the new strut:
- Position the new strut in place of the old one and secure it using the top nut. Ensure it is torqued to the manufacturer's specifications (typically around 25-30 ft-lbs).
Reinstall the spring:
- Carefully position the spring onto the new strut and decompress the spring to secure it in place.

4. Reinstall Strut Assembly

Insert the strut back into the vehicle:
- Position the strut into its original location and align it with the mounting holes.
Secure the lower strut bracket:
- Install and torque the lower strut bolts to the manufacturer's specifications (typically around 85-95 ft-lbs).
Reconnect the sway bar link:
- Reinstall the sway bar link and torque the bolt to the specified value.
Secure the top strut nuts:
- Tighten the top nuts to the appropriate torque, ensuring the strut is secure against the mount.

5. Reassemble and Lower the Vehicle

Reinstall any engine covers or components removed for access.
Replace the wheels and lower the vehicle to the ground.
