Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Step 1: Locate the power steering reservoir and check the fluid level.
Step 2: If low, siphon out the old fluid using a turkey baster and refill with manufacturer-recommended power steering fluid.
Step 3: Start the engine and turn the steering wheel to full lock several times to bleed any air from the system.

3. Replace Damaged Components

Step 1: If any worn components were identified (e.g., tie rods, ball joints, or CV joints), remove them using a socket set.
Step 2: Install new parts in the reverse order of removal, ensuring to torque to manufacturer's specifications.
Step 3: Reassemble any covers or shields that were removed during the process.

4. Wheel Bearing Inspection/Replacement

Step 1: Remove the wheel by loosening the lug nuts and lifting the vehicle with a jack.
Step 2: Inspect the wheel bearings for any play or grinding noise. If damaged, remove the hub assembly and replace the bearings.
Step 3: Reinstall the wheel and lower the vehicle back to the ground, ensuring the lug nuts are torqued to specification.
