The differential seal is vital because it maintains the oil under control in the differential and the oil lubricates specific gears.
Differential seal significanceThe differential seal is the seal found at the output shafts of the vehicle's differential. In most cases, the seals are composed of materials like rubber and metal but they do tend to wear out and fail in the long run. This component typically seals the axle shafts making them come into contact with the differential and keeping fluid from leaking. Sometimes the differential seal helps maintain the axle shafts aligned correctly with the differential.
Common problems with a failing differential sealA failing differential seal can cause whining from the differential and oil leaks.
