How often should I regrease my boat trailer bearings?
This depends on several factors which can include: the amount of use, the load you are carrying, wheel size, and driving conditions i.e. hot dusty, dirty roads. At minimum grease should be added to the bearings at least twice per season and more often if pressurized grease fittings bearing buddies are not used in the wheel hubs and frequent trips to the lake are encountered.
