    When I bought our 10 yo Jayco, I asked the previous owner if he ever did the bearings, he hadn't. He was the second owner and had the camper 5+ years. I went ahead and replaced the bearings because I was going to tear the hubs down anyway for inspection, and for peace of mind. Call it cheap insurance. 10 years may be a bit too long for hub service as the grease was showing some age but I'm sure it was still doing the job. With that said, my fil never had any hub maintenance done on his pups and he subjected them to heavy use on his annual 4 month jaunts around the country, so maintenance seems optional, ymmv. But I'm a better safe than sorry guy. Really really really don't want to be on the side of the road with smoking hubs, or looking at a spindle/axle replacement.

    Good call on your part! I even keep a spare set stowed in the camper just in case.

    Entertaining thread. ;) I don't worry about bearings any where near as much as I did 30 years ago. When I towed boats up and down the east coast with small wheels I used to carry a spare hub with fresh bearings pre-installed. Last thing I wanted to do by the side of the road was replace blown bearings (once was enough).

    Bearings have become better, wheels have become larger, many trailers now have bearing buddies or similar, all my recent Ranger boats have had oil filled hubs, things are much easier. All I do these days is keep them greased, check for heat and or wiggle at gas stops - and maybe have them replaced every 5 years or so. (assuming I keep the toy that long ;) )

    You can get a kit with all the parts.

    I carry the tools. Even if I didnt, I'd rather have the parts on the road than not. You can always call a roadside service truck to do the work.

    I think that the grease gets hard and maybe thickens up from not rotating regularly, so when we hook up and tear out headed to the lake there is a time they are dry. Big trucks don't use grease in their wheel bearings they use oil because the bearings are submerged instantly after sitting for awhile. They make some oil fill kits for smaller axles and I am thinking about putting some on our new ride. I did not put them on our pup because the wheels had center caps and I could not see the oil caps. I think you could run 90 wt. oil in the ezy. lube hubs.

    Yesterday, pulled the hub off a trailer that I know hadn't been apart since I bought it in 1996. It was ten year old when I bought it. I put Bearing Buddies on when I got it and have always given them a pump or two of grease at the beginning of towing season. The trailer had been sitting since October. The 25 year old grease was still bright green and very soft. The only reason I pulled the hub was to replace a grease seal.
