A Quick Guide to Properly Greasing All Your Trailer Wheel Bearings

Lubrication affects the life, torque, speed, noise, temperature, and rust prevention of quality trailer wheel bearings; this being the case, whenever a bearing performs under demanding conditions, lubrication becomes crucial. This is where grease comes in; an oil type lubrication that has been enhanced with thickener to prevent oil migration from the lubrication site, it is used when frequent replenishment of lubricant is undesirable or impossible. Most oil types can be used as grease bases which are added to metallic soaps, thickeners, and synthetic fillers.

Trailer Bearings

To keep all a vehicle’s wheels turning properly, wheel bearings are needed. They must be kept lubricated so that they function correctly at all times. To this end, a WikiHow article lists the proper steps for greasing trailer bearings.

The article begins with jacking the trailer up and removing the lug nuts and the wheels using a lug wrench, then prying off the hub dust cap so you can determine whether or not you need to replace any bearings. With a brush and a pan of kerosene gasoline, the article suggests cleaning off as much dirt and old grease as possible from the inner and outer bearings. Then a thorough inspection of the bearings and other parts should be done to determine if replacement is necessary; afterward, the bearings need to be packed with grease by a bearing packer, a grease gun, or by hand.

Greasing bearings is a tedious task, but it is necessary to keep machinery running at optimal levels. A well-stocked trailer parts store like Champion Trailers offers trailer wheel bearing parts and grease for any bearing maintenance work.
