• We recommend replacing the inner seal when removing an axle shaft. As it makes sense to change both sides and both seals at the same time, the total install time will equal 4.9 hours. The install time includes both the left- and right-side axle shafts, (2) inner seals, removal of differential, adding oil, and axle reassembly.
