Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather necessary tools and parts.

2. Check Power Steering System

Tools Required: Socket set, power steering fluid.
Inspect the power steering fluid reservoir for proper fluid level.
If low, top off with the recommended power steering fluid.
Look for leaks in power steering hoses and connections.

3. Inspect and Replace Serpentine Belt

Tools Required: Socket set, pry bar, serpentine belt tool.
Release tension from the serpentine belt using a belt tensioner tool.
Remove the serpentine belt and inspect for wear, cracks, or fraying.
Replace the belt if damaged; install a new belt by routing it according to the belt diagram.

4. Inspect Wheel Bearings

Tools Required: Jack, jack stands, socket set, torque wrench.
Lift the front of the vehicle and secure it on jack stands.
Spin each front wheel while listening for grinding or roughness, which indicates bad bearings.
If faulty, remove the wheel and hub assembly to replace the bearings.

5. Check Transmission Fluid

Tools Required: Transmission fluid, funnel, dipstick.
Check the transmission fluid level using the dipstick; add fluid if low and inspect for burnt smell or dark color.
If the fluid appears contaminated, a transmission fluid change may be necessary.
