Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and glasses.

2. Inspect and Refill Power Steering Fluid

Locate the power steering reservoir.
Check the fluid level; if low, add the appropriate type of power steering fluid as specified in the owner’s manual.
Start the engine and turn the steering wheel from lock to lock to purge air bubbles.

3. Replace Serpentine Belt (if worn)

Disconnect the negative battery terminal.
Use a socket wrench to relieve tension on the serpentine belt tensioner.
Remove the old belt and inspect the pulleys for damage or wear.
Install the new serpentine belt according to the routing diagram.
Reconnect the battery terminal.

4. Inspect and Replace Transmission Fluid (if needed)

Raise the vehicle and securely support it with jack stands.
Locate the transmission fluid dipstick; remove it and check fluid level and condition.
If low or dirty, drain the transmission fluid using a drain pan.
Replace with new transmission fluid according to the manufacturer's specifications.
Recheck fluid level and ensure it’s within the acceptable range.

5. Check and Refill Differential Fluid (if necessary)

Inspect the differential housing for leaks.
Remove the fill plug and check fluid level with your finger; fluid should be just below the fill hole.
If fluid is low, add the specified differential fluid until it begins to seep out of the fill hole.
Replace the fill plug securely.
