how to fix Honda CR-V Fifth Generation (2017-2022) differential noise

Solution

1. Preparation

• Gather tools and parts required.
• Park the vehicle on a flat surface and engage the parking brake.
• Disconnect the negative battery terminal to ensure safety.

2. Fluid Inspection

• Tools Required: Socket set, fluid pump, container
• Check the differential fluid level using the fill plug.
• If low, drain the old fluid into a container.
• Inspect the fluid for metal shavings or burning smell; if found, further internal inspection is needed.

3. Replace Differential Fluid

• Tools Required: Fluid pump, new differential fluid (OEM specified)
• Refill the differential with the appropriate fluid until it reaches the fill plug level.
• Replace the fill plug and torque it to the manufacturer's specification.

4. Inspect and Replace Bearings (if necessary)

• Tools Required: Socket set, bearing puller, torque wrench
• If noise persists, remove the differential cover and inspect the bearings.
• Replace any damaged bearings with new OEM parts.
• Reassemble the differential cover using a new gasket and torque bolts to specifications.

5. Final Assembly

• Reconnect the negative battery terminal.
• Ensure all tools are removed from the work area.
