Solution

1. Preparation

Gather Tools and Parts: Ensure you have the following tools and parts ready:
- Tools: Jack and jack stands, socket set, torque wrench, alignment tool
- Parts: New tie rods, control arms, or any other damaged components identified in diagnostics
Safety: Disconnect the battery to prevent electrical issues during repairs.

2. Lift the Vehicle

Use the jack to lift the front of the vehicle and securely place it on jack stands.
Remove the front wheels using a socket set to access steering and suspension components.

3. Inspect and Replace Damaged Components

Steering Components:
- Check tie rods for bends or breaks.
- If damaged, remove the old tie rod by loosening the locking nut and separating it from the steering knuckle.
- Install the new tie rod, ensuring it is torqued to manufacturer specifications (usually around 40-50 lb-ft).
Suspension Components:
- Inspect control arms and ball joints for damage.
- If any component is damaged, remove it by loosening bolts and nuts, and replace with new parts, torquing to specifications (typically 50-70 lb-ft for control arms).
Reassemble:
- Reinstall the wheels and lower the vehicle back to the ground.

4. Wheel Alignment

Use a wheel alignment tool to check and adjust the alignment of the front wheels.
Follow the manufacturer's specifications for toe, camber, and caster adjustments.
