Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface, and the engine is off.
Tools Required:
- OBD-II scanner
- Socket set
- Torque wrench
- Floor jack and jack stands
- Safety goggles and gloves

2. Check and Replace Transmission Fluid

Step 1: Locate the transmission dipstick (if applicable) and check the fluid level.
Step 2: If the fluid is low or dirty, drain the old fluid using a drain pan.
Step 3: Replace the transmission filter (if applicable) and refill with the recommended transmission fluid (Honda ATF DW-1).
Step 4: Start the engine and let it run for a few minutes to circulate the fluid; check for leaks.

3. Inspect and Replace Serpentine Belt

Step 1: Locate the serpentine belt and inspect it for cracks or excessive wear.
Step 2: Use a socket wrench to release tension from the belt tensioner and remove the old belt.
Step 3: Install the new serpentine belt following the path indicated on the belt routing diagram.
Step 4: Reapply tension and ensure the belt is properly seated on all pulleys.

4. Inspect Wheel Bearings and Differential

Step 1: Lift the vehicle securely on jack stands and remove the wheels.
Step 2: Grab the wheel at 3 and 9 o'clock positions and shake to check for play.
Step 3: If play is detected, remove the hub assembly and replace the wheel bearing.
Step 4: Inspect the differential fluid level and condition, and replace if necessary.
