Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and use wheel chocks.
Disconnect the battery before starting work on electrical components.

2. Inspect and Replace Power Steering Fluid

Tools Required: Fluid pump, funnel
Check the power steering fluid level; if low, top it off with the manufacturer-recommended fluid.
If the fluid appears contaminated, drain and replace with new fluid.

3. Replace Worn or Damaged Components

Tools Required: Socket set, torque wrench, jack stands
If any steering or suspension components are found damaged (e.g., tie rods, control arms), remove them using a socket set.
Install new components, ensuring to torque them to the manufacturer's specifications.

4. Inspect and Replace CV Joints if Necessary

Tools Required: CV joint removal tool, grease
Remove the wheel and axle nut, then detach the CV joint from the steering knuckle.
Inspect the CV boot for tears; if damaged, replace the CV joint and repack with grease.
Reassemble the joint and ensure proper torque on all fasteners.

5. Wheel Bearing Replacement (if required)

Tools Required: Bearing puller, press
Remove the wheel and brake assembly.
Use the bearing puller to extract the old wheel bearing.
Press in the new bearing, ensuring it is seated correctly.
Reassemble the brake assembly and wheel.
