Solution

1. Preparation

Gather tools and parts as specified below.
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 Serpentine Belt

Remove the engine cover if applicable.
Locate the serpentine belt tensioner and release tension on the belt.
Carefully remove the belt from the pulleys.
Inspect the belt for cracks, fraying, or glazing; replace if necessary.
Install the new belt, ensuring it is routed correctly around all pulleys.
Reapply tension to the belt using the tensioner.

3. Check and Top Off Fluids

Locate the transmission fluid dipstick; check the fluid level and condition.
If low, add the appropriate type of transmission fluid until the correct level is reached.
Repeat the process for the power steering fluid reservoir.
Check for leaks while the vehicle is running and top off fluids as needed.

4. Inspect Wheel Bearings

Lift the vehicle using a jack and secure it with jack stands.
Spin each wheel by hand to listen for any grinding or roughness indicating bad bearings.
If noise is detected, remove the wheel and replace the bearing using a bearing press.

5. Examine Differential and Axles

Inspect the differential for any visible leaks or damage.
Check the axle shafts for any signs of wear or play.
If necessary, replace damaged axle components or seals.
