Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, inspection mirror.
Safely elevate the vehicle and secure it with jack stands.
Remove the front wheels using the lug wrench.

2. Inspect and Replace Worn Suspension Components

Inspection:
- Examine control arms and bushings for cracks or excessive wear.
- Check shocks/struts for leaks or physical damage.
Replacement (if needed):
- Remove the old control arm or shock/strut using appropriate socket sizes.
- Install the new component and torque to manufacturer specifications (usually around 70-85 lb-ft for control arm bolts, check specific vehicle specs).
- Reinstall the wheel and torque lug nuts to 140 lb-ft.

3. Align the Wheels

After replacing any components, perform a wheel alignment using a professional alignment tool.
Adjust the camber, caster, and toe settings to align with manufacturer specifications.

4. Inspect and Tighten Steering Components

Check tie rods and ball joints for play; replace any that are worn.
Ensure all connections are tight; torque tie rod ends to manufacturer specifications (typically around 35-45 lb-ft).
