Wheel bearing repacking
How often do you repack the RV wheel bearings? I'm getting many different opinions on this question.

Somewhere between 3 days and 30 years. 😉
Assuming it's done properly, it should be good for 20-30k miles but unlike a semi, most people only tow a couple thousand miles per year (if that), so they often revert to a time basis (annual, biannual, etc...) as it's easier to track but which is likely overkill as the grease doesn't go bad or pick up contaminants.
Result, you get recommendations that are all over the place. If you want something more definitive, look up the axle brand and they should have a recommendation online.
you would be surprized how dark and oxidized the grease is when I take the old stuff out at the biging on the season. I never used to repack them very often at all, but after having an incident with my brand new 5th wheel, never packed properly or enough at the factory, I just put new grease in every year now, takes me a hour or two and 30 bucks. I also now use a IR thermomitor intermittiantly to check running temps to hopefully catch a issue before it happens, so far no issues since I started doing that. I would recomend anyone buying a brand new trailer either service the berrings or get the dealership to do it as a condition of sale before it comes off the lot. as I found out the issue I had is actualy quite comon..
