Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and flashlight.
Ensure the vehicle is on a flat surface and the parking brake is engaged before beginning work.

2. Inspect Suspension Components

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels to access the suspension components.
3. Visually inspect control arms and bushings for cracks or excessive wear.
4. Use a pry bar to check for play in the control arm bushings.

3. Check CV Joints

Sub-steps:
1. Examine the CV joints for any damage or torn boots.
2. Rotate the wheel while observing the CV joints for clicking or clunking sounds.
3. If damaged, replace the CV joint or axle assembly as necessary.

4. Inspect Power Steering System

Sub-steps:
1. Locate the power steering reservoir and check fluid levels.
2. Look for leaks around the power steering pump and hoses.
3. If the fluid is low or contaminated, flush the system and refill with the correct power steering fluid.

5. Assess Wheel Bearings

Sub-steps:
1. Grab each wheel and check for lateral play by pushing and pulling.
2. Spin the wheel to listen for grinding noises that indicate bearing failure.
3. If bearings are worn, replace them per manufacturer specifications.
