What is the normal life of rear axle bearings?
Rear axle bearings can last the life of the vehicle, well over 250,000 miles when properly lubricated. Lubrication of the rear axle bearings is a function of oil level and condition in the rear differential. Even small leaks should be addressed immediately. Fluid level should be checked whenever there is a sign of a leak. Differential oil should also be replaced at recommended intervals.
