What Can Cause A Differential To Fail?

Trans Tech Auto & Truck tells our customers in the Colorado Springs area that the differential in a vehicle is no different than any other component in that it is subject to wear and some vehicle's differentials fail before others. The leading cause of a differential failing is due to using the wrong lubricant type and specialty lubricants. Water can also be a culprit to a differential failing as it can enter through the vent or seals. This often happens when driving in high water. When water enters it will emulsify the differential lubricant and result in rusting on gear and bearing surfaces. Seized U-joints that result in vibration can cause differential failure as well.
