Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace Serpentine Belt

Sub-steps:
1. Use a socket set to remove the engine cover if necessary.
2. Inspect the serpentine belt for wear, cracks, or fraying.
3. If damaged, use a belt tool to release the tensioner and remove the belt.
4. Install the new serpentine belt according to the routing diagram found in the engine bay.
5. Reconnect the battery and start the engine to check for noise.

3. Check Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and wipe it clean.
2. Reinsert the dipstick and remove it again to check fluid level and condition (should be red and not burnt).
3. If fluid is low or dirty, drain and replace with the manufacturer's specified transmission fluid.
4. Recheck the level after filling.

4. Inspect Wheel Bearings and CV Joints

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Check wheel bearings for play by gripping the wheel at 12 and 6 o'clock and pushing/pulling.
4. Inspect CV joints for any torn boots or excessive grease leakage.
5. Replace any worn bearings or joints as needed.
