Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Suspension and Steering Components

Tools Required: Socket set, torque wrench, flashlight.
Remove the front wheel using a socket set.
Inspect control arms, ball joints, and tie rod ends for wear or damage.
If any components are damaged, proceed to replace them.

3. Check and Replace Power Steering Fluid

Tools Required: Fluid pump, clean container.
Locate the power steering reservoir and check the fluid level.
If fluid is low, add manufacturer-recommended power steering fluid.
If the fluid appears dirty or contaminated, drain and replace it entirely.

4. Inspect CV Joints and Axles

Tools Required: CV joint removal tool, jack stands.
Lift the vehicle using a jack and secure it with jack stands.
Inspect the CV joints for any tears in the boot and signs of grease leakage.
If damaged, remove the affected axle and replace it with a new one.

5. Check Wheel Bearings

Tools Required: Bearing puller, grease.
Spin the wheel while it’s off the ground to feel for roughness in the bearings.
If rough, remove the wheel and hub assembly to access the bearings.
Replace the bearings as necessary and re-grease before reassembly.
