Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Jack and jack stands
- Spring compressor
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the battery to prevent any electrical issues during repair.

2. Lift the Vehicle

Use a jack to raise the vehicle and secure it with jack stands.
Remove the wheel for access to the strut assembly.

3. Remove the Strut Assembly

Locate the strut mounting bolts at the top and bottom of the strut.
Use the socket set to remove the lower strut bolts first.
Remove the top mount bolts (may require accessing the engine bay or under the dashboard).
Carefully detach the strut assembly from the vehicle.

4. Inspect and Replace

Inspection: Check the strut for any signs of leaks, damage, or wear.
Replacement: If worn, install the new strut:
1. Use a spring compressor to safely compress the coil spring.
2. Attach the new strut to the spring and secure it according to manufacturer specifications.
3. Reinstall the strut assembly in reverse order of removal, ensuring all bolts are torqued to the manufacturer’s specifications.

5. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value.
Reconnect the battery.
