Axle Lubricant

Fluids & Filters


Axle lubricant is a specially formulated oil that is capable of handling high-pressure loads. The lubricant comes in various viscosities to meet different specifications. Axle lube may be formulated from mineral oil or synthetics.


Axle lube provides lubrication for the various gears and bearings in the rear axle of rear-wheel-drive cars and trucks. Axle lube is also used in the front axle of four-wheel-drive light trucks.

Maintenance Tips/Suggestions

Have the axle lube level checked with every oil change. Check your vehicle's owner's manual to find out the recommended interval for axle lube changes. Many manufacturers claim their axles as "lubed for life", unless the axle has been submerged in water. If you have a pickup or SUV, this may happen quite often, especially if you pull a boat. If this is the case, have the axle lube changed at least once a year. In cold climates, you may want to consider changing the standard axle lube to synthetic. Synthetic lubes flow easier in cold weather, improving lubrication. With a 4x4, this is doubly the case because of the two axles. Always use a lubricant that meets or exceeds the manufacturer's lube specifications.
