A whining or howling noise that changes with vehicle speed or between acceleration and deceleration can sometimes indicate wear or improper operation inside the differential. Gear wear, bearing problems, lubricant condition and other factors may affect the sound.
Similar noises can also come from wheel bearings, tires or other drivetrain components, so the sound alone does not identify the repair. Certified Transmission in Bellevue can inspect and test the vehicle to determine whether the differential is actually causing the noise.
