Looking closely at the trailer bearing and race surfaces to see if there are any nicks or discolorations.Grease can break down on stored trailers, then corrosion can form. The general thought consensus is that trailer wheel bearings should be serviced annually or every 10,000 km.There are some greases out there that are not compatible with others. Make sure to thoroughly clean all old grease from the bearings, races and hub cavities using brake cleaner.Do NOT reuse cotter pins, they are one of the least expensive parts and is one of the most important.Mechanical problems can arise as well including damaged shocks, struts, suspension out of alignment and over or under inflated tires.īearings will often create unnatural sounds that, depending on speed, will often indicate that the bearings need attention. It can lead to excessive wear on the inside or outside edges of the tires. If the wheel bearing is damaged, it can cause the tire and wheel to not align to the hub, this creates abnormal tire wear. If the wheel bearing fails, it is often due to a lack of grease inside the wheel bearing housing. When wheel bearings are packed with grease correctly, it spins freely and does not develop excess heat. They will eventually wear out, but you can extend the span of them by maintaining them. Over time the trailer bearings will take a large amount of abuse and wear, although they are designed to last for a long time, they will wear out prematurely if they are not routinely taken care of. Repacking a bearing is the process of removing the parts of the wheel to access, clean and add grease to the bearings.
#How to repack bearings how to#
You may have heard the term “repacking” bearings, and owning a trailer it is a good idea to know how to clean and “repack” them. This can be a quick DIY job if you know what you are doing, if you are unsure, call your local mechanic to make an appointment. Over time, grease breaks down, heat that is produced by the brakes speeds this up, and since a trailers weight rides on the wheel bearings it is very important to keep them well lubricated. Why repacking trailer bearings is important
