Solution

1. Preparation

Gather tools and materials: jack and jack stands, socket set, torque wrench, power steering fluid, and a flashlight.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Replace Power Steering Fluid

Fluid Check: Open the hood and locate the power steering reservoir. Check the fluid level and condition.
Replacement: If the fluid is low or contaminated, siphon out the old fluid using a turkey baster.
Refill: Add the appropriate type of power steering fluid as specified in the owner's manual.

3. Inspect Wheel Bearings

Lift Vehicle: Use a jack to lift the front of the vehicle and secure with jack stands.
Check Bearings: Grab the wheel at the 12 and 6 o’clock positions and shake it. If there is play, the bearings may need replacement.
Removal: Remove the wheel, brake caliper, and rotor to access the wheel bearings.

4. Replace Worn Wheel Bearings

Remove Old Bearings: Using a bearing puller, extract the old bearings from the hub assembly.
Install New Bearings: Place the new bearings in the hub and press them in using a bearing press.
Reassemble: Reinstall the rotor, caliper, and wheel. Torque the lug nuts to the manufacturer’s specifications.

5. Inspect Suspension Components

Visual Inspection: Check all suspension components (control arms, bushings, tie rods) for signs of wear or damage.
Replacement: If any components are worn or damaged, replace them using appropriate tools and torque specifications.
