why does my Ram 1500 DT (2019-Present) make a whining noise when driving

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, fluid level gauge, mechanic's stethoscope, jack and jack stands.
• Ensure the vehicle is parked on a level surface and the engine is turned off. Disconnect the battery if necessary for safety.

2. Fluid Changes

• Transmission Fluid:

  1. Raise the vehicle using a jack and secure it with jack stands.
  2. Locate the transmission pan and drain plug.
  3. Remove the drain plug and allow fluid to completely drain into a pan.
  4. Replace the drain plug and refill with manufacturer-recommended transmission fluid through the dipstick tube.
  5. Check the fluid level and ensure it is within the safe range.

• Power Steering Fluid:

  1. Locate the power steering reservoir.
  2. Remove the cap and check the fluid level.
  3. If low, top up with manufacturer-approved power steering fluid.
  4. Start the engine and turn the steering wheel left and right to circulate the fluid, then recheck the level.

• Differential Fluid:

  1. Find the differential cover and drain plug.
  2. Remove the drain plug to let old fluid drain completely.
  3. Replace the drain plug and refill with appropriate differential fluid until it reaches the fill hole.

3. Belt and Pulley Inspection

1. Inspect all drive belts for signs of wear, fraying, or cracking.
2. Check belt tension and adjust if necessary.
3. Examine pulleys for proper alignment and bearing condition.
4. Replace any damaged belts or pulleys as needed.

4. Final Checks

1. Reconnect the battery if it was disconnected.
2. Take the vehicle for a test drive to confirm the whining noise has been resolved.
3. Monitor for any reoccurrence of the noise or related symptoms.
