I tried the slide hammer but I haven't tried heat. I just checked out a few YouTube videos and I didn't realized heating the hub was a common practice. I'll give that a shot tomorrow . Thanks!

I happened to have a blind bearing puller in my harbor freight stash and the largest puller fit. A little heat and I'm done. Bearings were rolling good but this rust was a bit more than I expected.

keep in mind, the outer race is uncoated and it will rust from simple atmospheric exposure. That's not necessarily from the ball bearings themselves.

I agree but if you look close at the bottom of the bearing you can see the outer casing has completely rusted through to allow water to enter. That bearing was on borrowed time.

pop the rubber seal off with a needle or a pick to see if water actually got inside.

My 2008 came with the orange ones too. Failed full of water in less than 15,000 miles.

Mine were seriously FULL of water though. I pushed upon the seal and a drop came out!

After heating the hub, the entire spacer was covered in condensation but I think I heated the bearing up enough to burn off any water inside. It's clear from that chunk rusted out that water was getting in. I think I was on borrowed time. I was thinking of filling the axle cavity with grease but then I saw it's a massive cavern. So I'm gonna do the antiseize paint job I've seen others do. This is just a bad design for an adventure bike. I can't believe Eric didn't see this coming! He did such an awesome job of designing this bike, to the point it would be competitive with today's adventure bikes. It's sad something like this can side line you.

I never felt the need to check sealed bearings but now I do!!!! I received NEW OEM Buell rear bearings made in Korea. After seeing this video and hearing about failures I decided to check these new bearings. The first one I opened had virtually NO grease. To the point you couldn't see any but if you touch it you can feel a very light coating. So I thought, maybe that's the way they are. I opened the second bearing and it was full. You can see the grease swirled around on each ball and globs on the carrier. The point to this is clear, the bearing with very little grease would have failed with only a few thousand miles. Maybe sooner if moister got in. From now on I am greasing my own sealed bearings and this video shows you how to do it. I'm a little pissed I spent extra money for what would have been a failed part. I blame the manufacture, not the vendor who has treated me extremely well.

I wish I took some pics but I'll do it when I get to the front wheel bearings.

It doesn't take a lot of grease in a ball bearing. You can actually put too much grease in. In high speed applications to much grease will blow the seals off. Bearings are smart, they know how much grease they need and will overheat if they can't get rid of excess. Just saying that because the guy in the video was putting too much in. If you pack half of the bearing full that is more than enough.

Quite often, a brand new bearing will show grease only on one side. That's how they are filled to the correct level.

It took four caulking gun tubes of marine grease to fill that cavernous rear hub. The seals have never blown out from too much grease. Over time and miles it does get a little bit of a thin grease film that collects dust. But I can confirm that my bearings are not running dry or wet with water.

Etennuly, that's a lot of grease!!! I was going to fill the hub until I realized its massive. You must have two big tubes of grease in there! LOL
Tootal, I hear what you are saying and I think the video even warns of over greasing. I filled it to the equivalent of the bearing that did have grease. That was the point. One was well greased while the other barely had anything. Mass production can't check them all it seems. They are weighted at the end of production but I guess 1 squirt of grease is almost the same as 2 squirts of grease. I'll be checking from now on. The only bearing manufacture I trust is Timken but I couldn't find a Timken bearing for our wheels.

Array, thank you! I googled the crap out of those bearings and I couldn't find anything to cross references the OEM Buell bearing. I'll write this in my manual if there is a next time.
