why does my Ford F-150 Fourteenth Generation (2021-present) make a whining noise when driving

Solution

1. Preparation

• Tools Required: OBD-II scanner, jack and jack stands, torque wrench, fluid catch pan, safety goggles, gloves.
• Safety Warnings: Disconnect the battery before working on electrical systems, ensure the vehicle is secure on jack stands, and allow the engine to cool before inspection.

2. Replace Serpentine Belt (if needed)

1. Remove the serpentine belt:
   • Use a ratchet and socket to relieve tension on the serpentine belt tensioner.
   • Slip the belt off the pulleys and remove it from the engine bay.
2. Install the new serpentine belt:
   • Route the new belt according to the belt routing diagram, ensuring it sits properly on all pulleys.
   • Reapply tension using the tensioner and check for any misalignment.

3. Change Transmission Fluid (if needed)

1. Drain the old fluid:
   • Place a fluid catch pan under the transmission.
   • Remove the transmission pan bolts and let the fluid drain completely.
2. Replace the filter:
   • Remove the old filter and install a new one, ensuring a proper seal.
3. Reinstall the transmission pan:
   • Clean the pan and the surface of the transmission.
   • Reinstall the pan with a new gasket and torque bolts to manufacturer specifications (usually around 10-12 ft-lbs).
4. Add new transmission fluid:
   • Using a funnel, add the recommended type and amount of transmission fluid through the dipstick tube.

4. Inspect Wheel Bearings and Hubs (if needed)

1. Lift the vehicle:
   • Use a jack to lift the front or rear of the vehicle and secure it on jack stands.
2. Remove the wheel:
   • Take off the wheel using a socket set to access the hub assembly.
3. Check for play:
   • Grasp the hub and wiggle it to check for excessive play or noise.
4. Replace bearings if necessary:
   • If play is detected, remove the hub assembly and replace the bearings, applying grease as needed before reinstalling.
