Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, multimeter.
Ensure the vehicle is parked on a flat surface and the engine is off.
Place wheel chocks behind the rear wheels for safety.

2. Inspect Suspension Components

Raise the front of the vehicle using a jack and secure it with jack stands.
Remove the front wheels.
Sub-steps:
- Inspect the struts and shocks for leakage and physical damage.
- Check control arm bushings for wear or cracking.
- Examine sway bar links for looseness or damage.

3. Replace Worn Suspension Parts

If any components are found to be damaged or worn, replace them as follows:
- Remove the old strut or shock by unbolting it from the top mount and lower mount.
- Install the new strut or shock, tightening bolts to manufacturer specifications (check repair manual for torque values).
- Reinstall the wheels and lower the vehicle.

4. Perform a Wheel Alignment

After replacement, take the vehicle to a professional shop for a four-wheel alignment to ensure proper handling and tire wear.
