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..

oh I know I am probably a little overkill with once a year.. but when you get a berring that is glowing red 1/2 way home on your first trip you tend to watch them a little harder. that was a fun trip home, little short drives with cool down stops for 200 miles. My first three trailers (old chalet, a tent trailer then a 28 foot trailer) I never checked them at all in 20 years they occupied, although I didn't have internet forums back then so there was nothing to make me paranoid 🤣if I had to pick a minimum I think I would do it every 3 years.. if the rv industry would switch over to cartrage bearings like most vehicles have you would never have to worry about it again.

its not a case of how much you use in a ezlube axel, its how you put it in, if you squirt it in to fast it can get out of the seals onto the breaks, and if your not spining the tire as you put it in it cound go throuhg the seals. you do want to put lots, the ide is to force the old grease out into the center cup area around the grease nozel and clean that out. that way you know you have fresh greese through out the berring.

  I repack my bearings every fall before I park the TT. I also carry my IR thermometer and check my hub temps every morning after about 50 miles of travel. If I have a warm bearing, I can repack it right away. It would not take me very long to strip t down and repo it. I do carry a pretty good tool kit, jack, and stand. I have never had to do it on the road.
  We put 3000 to 10000 miles on annually.

    I also check my hubs with an IR thermometer. For me it's more for post brake adjustment checks than hot bearings. I would think that an unexpected hot hub reading (not brake adjustment related) would be a bigger issue than just needing fresh grease.
    In my experience, a hot hub showed up after greasing a bearing - castle nut was too tight. From now on, I have a center punch mark at 12 o'clock on all my castle nuts, to reinstall the castle nut in the same position/rotation as before the re-pack process.
