Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat, level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert the dipstick, remove it again, and check the fluid level.
If low, add the manufacturer-recommended transmission fluid until it reaches the correct level.

3. Inspect Drive Belts

Visually inspect the drive belts for cracks, fraying, or signs of wear.
If any damage is observed, use a socket set to remove the old belt.
Install a new drive belt according to the manufacturer's specifications, ensuring proper tension.

4. Examine Differential and Transmission Mounts

Lift the vehicle using a jack and secure it with jack stands.
Inspect the differential and transmission mounts for cracks or deterioration.
If mounts are damaged, remove the old mounts using a socket set and replace them with new ones, tightening to the specified torque values.

5. Test Drive

After all repairs, reconnect the battery.
Conduct a test drive to ensure the whining noise has been eliminated.
