With fresh fluids in the rest of the drivetrain, it is now time to turn our attention to the axle lubrication. Where as we stated that the transfer case fluid leads a relatively easy life, the same is not true of the rear axle. The reason for this is heat; due to the relatively high frictional losses of the hypoid ring-and-pinion gears, axle lube temperatures can exceed 300F during high-speed cruising. While certain ultra-high-performance vehicles such as the Corvette Z06 have provisions for axle cooling, most of us aren't so lucky. Throw in the fact that this lube isn't filtered and is prone to contamination by water and other environmental matter, and it's essential that it be changed on a regular basis (two years or 25,000 miles isn't a bad starting point for a recommended service interval).
