Grease seals/ Axle issues
I know several have had issues with grease seals leaking onto brakes & damaging brakes. Found this on the Columbus RV Group FB page today. Seems the NHTSA has given Lippert and FR until May 9th to...

All info on greasing wheel bearings says to NOT fill the center of the hub with grease. When done properly a small amount is left in the center and this space sort of acts like a reservoir to allow a place for excess grease to go when it heats up and will go to either of two places, the space that you left in the hub or through the seals and into the brake area.
I realize there are people who seem to love the grease gun method, but hand packing every few years seems a lot better to give a chance to inspect bearings and races.
Doing this every year is a bit of overkill, provided you have quality bearings and do a proper job in the beginning. I personally don't think of Chinese bearings in that context. I could get bearings at a general price of 15 to 20 $ per wheel. I can also get genuine Timken made in the U.S. For 52.35 per wheel. (comes with peace of mind included ;).
As to the frequency of greasing, the heavy duty schedule in the shop manual for my dually Ram lists front wheel bearings to check and repack at 48,000 miles. I would think that there are only a very few RV trailers that would fit that category for yearly maintenance.
