Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, fluid catch pan, funnel.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with wheel chocks before lifting.

2. Check and Replace Serpentine Belt (if necessary)

Inspect the serpentine belt for wear or damage.
If damaged, remove the belt by loosening the tensioner with a wrench.
Install a new belt according to the routing diagram found on the engine cover.
Ensure the belt is properly tensioned and aligned.

3. Inspect and Change Transmission Fluid (if necessary)

Drain the old transmission fluid using a fluid catch pan.
Replace with manufacturer's recommended transmission fluid (check owner's manual for specifications).
Refill the transmission with new fluid using a funnel until it reaches the correct level.

4. Replace Wheel Bearings (if necessary)

Remove the wheel and brake assembly.
Use a socket set to remove the hub assembly.
Replace the wheel bearing with a new one, ensuring it's properly seated.
Reassemble the components and torque to manufacturer specifications.

5. Check and Service Differential (if necessary)

Drain any fluid from the differential.
Inspect for metal shavings indicating damage.
Refill with new differential fluid as specified in the owner's manual.
