Have a pace single axle enclosed trailer. It is really loaded down with tools and equipment, sometimes I wonder if I might be pushing it a little to hard with how much I load it coupled with the weight of my heavy right foot but it has continued to serve me well for almost 14 years. This winter I decide to do some additional maint and repairs to it since work has been slow so I decide to pull the wheels, brakes and bearings and replace them with new since the trailer has an estimated 100,000 miles on it. Well, now I've cleaned out all the grease and started repacking with new grease and bearings only I can't seem to decide on a grease. I did decide to go with a synthetic since I work it pretty hard with a heavy load and don't always check the bearings on a timely basis. Ended up with Amsoil series 2000 racing grease (was on the self at local auto parts store) but now I'm concerned that this may not be the best choice for my application. Read somewhere that the racing grease may wash out and that a more all purpose synthetic might be a better choice. I saw this "Green Grease" on the shelf at auto zone but I don't know anything about it. I would like to use a robust synthetic. Am I overthinking this? Will the Amsoil Racing grease be good or should I use a different grease for my rode hard put up wet trailer?
