Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, flashlight.
Ensure the vehicle is parked on a flat surface and turn off the engine.
Disconnect the battery if necessary, especially when working near electrical components.

2. Inspect Suspension Components

Sub-steps:
1. Lift the front of the vehicle using a jack and secure with jack stands.
2. Visually inspect control arms, bushings, and strut mounts for any cracks or excessive wear.
3. Use a pry bar to test for play in the bushings by pulling against the control arms.

3. Check CV Joints

Sub-steps:
1. Inspect the CV joint boots for any tears or grease leakage.
2. If damage is found, remove the wheel and brake assembly to access the CV axle.
3. Replace the CV joint or axle as necessary.

4. Inspect Wheel Bearings

Sub-steps:
1. Spin the front wheels by hand to check for any roughness or grinding noise.
2. If roughness is detected, remove the wheel and hub assembly to access the bearings.
3. Replace the bearings if they are worn or damaged.

5. Power Steering System Check

Sub-steps:
1. Check the power steering fluid level and top off if low.
2. Inspect the power steering lines for leaks or damage.
3. If leaks are found, replace the affected lines or seals.
