Yes. Thanks for the reference, Dave. I don't think I pump up my Bearing Buddies too much but I do get some grease coming out of them and getting here and there. It is likely time to replace the seals. One thing I am completely naive about is rebuilding trailer hubs. I assume bearings, bearing races, and seals are all replaceable at the same time and by an amateur such as myself, but I don't have a clue where to get the parts or how to know what to get. I could image the races may require some special equipment. Can anyone share any experiences or provide any advice? Thanks.

a double axle trailer for a M17 would be huge overkill. save you money, if you are worried about a double blowout, and get a second spare tire on a mount.
also, i would be very surprised if you trailer doesn't already have bearing buddy's. if there is a zerk in the center of the hub you already have them. if not then you don't.
DON'T overcharge them. DON'T add oil every time you launch or retrieve. you check the charge by pressing on the edge of the bearing buddy cap (the zerk is installed into the cap). if the cap wiggles when you apply pressure you have enough oil. overcharging a bearing buddy will blow the hub seals ... usually the inner seal. will spray everywhere making a mess of the wheel rim, boat hull, etc.
see this for my detailed discussion about bearing buddys and hub maintenance -
