Grease acts as a seal, shielding delicate bearings from road salt, dirt, and water.
Often use marine-grade grease or high-temp lithium to handle the heavy loads and potential water submersion. axle grease
Tractors and loaders often have specific "grease points" (zerk fittings) that require heavy-duty polyurea or lithium complex grease to handle rugged terrain. Maintenance 101: How to Grease Your Axle Grease acts as a seal, shielding delicate bearings
At its simplest, axle grease is a thick, heavy lubricant designed to reduce friction between moving parts in your vehicle's axle assembly. Unlike engine oil, which is thin and flows freely, grease is "viscous"—it's designed to stay exactly where you put it, even under extreme pressure and heat.
