Possible signs of a differential problem include whining or howling that changes with vehicle speed, clunking as load changes, vibration, or lubricant leaking around the differential housing or axle seals.
These symptoms are not exclusive to the differential. Tire wear, wheel bearings, driveshaft components, and mounts can create similar complaints.
Tell Certified Transmission in Council Bluffs when the symptom occurs and whether it changes during acceleration, coasting, or turning. If you experience severe grinding, binding, or a sudden change in vehicle control, stop safely and arrange assistance.
