Do Trailer Bearings Need to be Cleaned When Re-packing

I would remove the hubs and clean the bearings and the inside of the hubs. Just adding grease will allow any impurities that have entered the hub to remain in there with your bearings. Water, sand, salt and other road grime inevitably work their way into the bearings and will eventually cause damage if the bearings are not cleaned. You also get the added benefit of being able to inspect the bearings, races, hubs and brakes for wear or damage.

Knowing that your trailer is in good shape and will perform as needed when on a trip will give peace of mind that you are safe. I generally repack the bearings on my two trailers every other year. I do one per year and the task usually takes about an hour. If you have an easy lube style of axle on the trailer then adding grease is a good thing to do. Just do not add too much once the hub has been initially filled.

I am including some video links on how to inspect the trailer hub and how to repack the bearings on your trailer. Also, some parts links of some items that will help you when repacking your trailer bearings.
