how to check for Ford F-150 13th Generation (2015-2020) differential noise

Solution

1. Preparation

• Tools Required: Jack and jack stands, socket set, torque wrench, differential fluid, shop rags, and safety goggles.
• Ensure the vehicle is on a flat, stable surface and secure with jack stands.

2. Fluid Change

• Sub-steps:
  1. Drain Fluid: Remove the differential cover bolts and carefully drain the fluid into a pan.
  2. Inspect Fluid: Check the drained fluid for metal shavings or debris that could indicate wear.
  3. Clean Surface: Clean the differential housing surface to remove old gasket material.
  4. Replace Fluid: Refill the differential with the manufacturer-recommended fluid type (typically 75W-140 for F-150) through the fill plug until it reaches the recommended level.

3. Bearing Inspection and Replacement (if necessary)

• Sub-steps:
  1. Remove Differential Cover: If there is still noise, remove the differential cover to access the gears and bearings.
  2. Inspect Components: Check for wear on bearings, ring and pinion gears, and shims.
  3. Replace Bearings: If any bearings are damaged, remove them using a bearing puller and replace with new ones.
  4. Reassemble: Reinstall the differential cover, applying a new gasket or sealant as needed, and torque bolts to the manufacturer's specifications.
