Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Raise the front end using a jack and support it with jack stands.

2. Inspect and Replace Suspension Components

Remove Wheel
- Use a socket set to remove the lug nuts and take off the front wheel.
Inspect Suspension
- Check the struts, control arms, and bushings for signs of wear or damage. Look for cracks or excessive play in joints.
Replace Damaged Components
- If any component is found damaged, replace it:
  - For control arms, remove bolts using a socket set and replace with new control arms.
  - Replace bushings by pressing them out and installing new ones using a bushing tool.
  - If the strut is damaged, detach it from the assembly, replace it, and ensure proper torque specifications are followed during reinstallation.

3. Check and Replace Steering Components

Inspect Tie Rod Ends
- Check for play by wiggling the tie rod ends; if loose, replace them.
Replace Ball Joints
- If ball joints are worn, detach the control arm and replace the ball joints using a ball joint press tool.

4. Reassemble and Test

Reinstall Wheel
- Place the wheel back on and hand-tighten lug nuts.
Lower Vehicle
- Remove jack stands and lower the vehicle to the ground.
Torque Lug Nuts
- Use a torque wrench to tighten the lug nuts to the manufacturer’s specification.
