Solution

1. Preparation

Gather tools: socket set, jack stands, wheel chocks, and an OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is off before starting.

2. Inspect and Replace Worn Belts

Sub-steps:
1. Open the hood and visually inspect the serpentine and accessory belts for cracks or fraying.
2. If wear is evident, use a socket set to loosen the tensioner and remove the old belt.
3. Install a new belt, ensuring it is properly aligned on all pulleys. Refer to the vehicle's service manual for routing instructions.
Tools Required: Socket set, belt tensioner tool (if necessary).

3. Inspect and Replace Wheel Bearings

Sub-steps:
1. Jack up the vehicle and remove the front wheels using a lug wrench.
2. Inspect the wheel bearings for play or noise by rotating the hub by hand.
3. If bearings are worn, remove the brake caliper and rotor to access the hub assembly.
4. Replace the bearing by pressing it out and installing a new one using a bearing press.
Tools Required: Jack, lug wrench, bearing press, socket set.

4. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Check the fluid level and condition; it should be bright red and clear. If it's dark or smells burnt, it needs to be replaced.
3. Drain the old fluid using a drain pan, then replace with new transmission fluid as specified in the owner’s manual.
Tools Required: Transmission fluid, drain pan, funnel, socket set.
