Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Inspect and Top Off Power Steering Fluid

Locate the power steering reservoir under the hood.
Check the fluid level against the dipstick or markings on the reservoir.
If low, add the appropriate type of power steering fluid according to the owner’s manual.

3. Examine the Serpentine Belt

Locate the serpentine belt and inspect it for cracks, fraying, or wear.
If damaged, use a socket set to relieve tension on the tensioner and remove the belt.
Install a new serpentine belt by routing it according to the belt routing diagram.

4. Check and Replace Wheel Bearings

Lift the front of the vehicle and secure it on jack stands.
Spin the wheels by hand; listen for any grinding or roughness.
If noise is present, disassemble the hub assembly using a socket set and replace the wheel bearings.

5. Inspect Transmission Fluid

Locate the transmission dipstick and remove it to check fluid level.
If low or dark, drain the transmission fluid and replace it with the manufacturer-recommended fluid.
Use a funnel to refill through the dipstick tube.

6. Evaluate Differential and Drive Shafts

Inspect the differential for leaks and listen for noise while rotating the wheels.
Check the drive shafts and CV joints for any visible damage or excessive play.
If damaged, replace the affected components.
