Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, fluid catch pan.
Instructions:
- Ensure the vehicle is parked on a flat surface and the engine is off.
- Engage the parking brake and wear safety glasses.

2. Inspect and Top Off Power Steering Fluid

Sub-steps:
- Locate the power steering fluid reservoir (usually near the engine bay).
- Check the fluid level against the recommended marks on the reservoir.
- If low, add the appropriate grade of power steering fluid as specified in the owner’s manual.

3. Replace Worn Steering Components

Sub-steps:
- If any steering components (tie rods, rack and pinion) are damaged, they will need to be replaced.
- Use a socket set to remove the damaged component (note torque specifications for reinstallation).
- Install the new component and torque to manufacturer specifications.

4. Inspect and Replace Suspension Components

Sub-steps:
- If the inspection reveals worn struts or control arms, they should be replaced.
- Remove the wheel for easier access and support the vehicle securely on jack stands.
- Detach the control arm or strut using the socket set and replace it with a new part.
- Reinstall the wheel and lower the vehicle, torqueing the lug nuts to manufacturer specifications.

5. Check and Replace Wheel Bearings

Sub-steps:
- After jacking up the vehicle, spin the wheel and listen for grinding noises.
- Remove the wheel and inspect the wheel bearing. If it is damaged, remove it using a bearing puller.
- Install a new wheel bearing and ensure it is properly seated before reinstalling the wheel.
