Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety during inspection.

2. Inspect and Replace Belts

Tools Required: Socket set, wrench, belt tensioner tool.
Check the condition of the serpentine belt and any other accessory belts for wear or damage.
If worn, remove the old belt by loosening the tensioner and slipping the belt off the pulleys.
Install the new belt by routing it according to the belt routing diagram and ensuring proper tension.

3. Check and Replace Wheel Bearings (if applicable)

Tools Required: Jack stands, socket set, bearing puller.
Raise the vehicle and remove the wheels to access the wheel bearings.
Spin the hub to check for roughness or noise.
If faulty, remove the hub assembly, use a bearing puller to extract the old bearings, and install new bearings.

4. Inspect and Replace Fluid (if applicable)

Tools Required: Fluid pump, catch pan, funnel.
For transmission fluid, check the level and condition; replace if it appears burnt or contaminated.
Drain the old fluid using a catch pan, replace the transmission filter if necessary, and refill with manufacturer-recommended fluid.
