WTF!? Wheel Bearing Toast at 35k?

Really? The right rear is toast. the left and cush drive bearings are fine. Is this totally unheard of or what?

Mine went at about 35k as well...Maryland Mike's too, and several others as I recall. 35k +/- seems to be the sweet spot for replacing the rear bearings on the 919.

Well, fire the engines! Spur this iron space-pony on!

Yup. Sounds about right. I just do mine about every 50K kms just to be sure.

Yep right rear went at 37K....seems to be pretty common at that mileage.

That's about normal per most people who've posted. I replaced mine with Koyo bearings at 60K and will probably replace them again at 90K, if only to see how they fare vs the NSKs (who I don't think were as good at bearings) that Honda installed originally.

They come as a set, you might as well replace them as a set.

Put me down for right rear failure at 28k miles... And I mean failure. Galled up, broken and downright ugly.

I think I did that one only once. My local bearing shop didn't have that size. It's not as important.

Mine made it to 38,074 miles before being changed out. It was so sloppy that you could wiggle the rear wheel and see the axle wallow in the bearing, but only on the brake side. Now coming up on 70k and I am ready for the next change.

Had mine done at 30k for good measure, nothing wrong with them at the time. Cush, and the two in the wheel all at one time.

Get the set from Boss bearing (Ebay), a little more than all ball but they are highly regarded Japanese bearings, not Chinese. They're still cheaper than going Honda replacements.

Legitimate question - do you consider 35k miles low mileage for a sealed bearing?

Should be pointed out that many motorcycle bearings, no matter who made the bike, rarely last *longer* than 30-40K these days with normal urban riding. If you replace them with All Balls' Chinese made bearings, you're looking at maybe 15-20K, which is why I sought out and found those Koyos that people are recommending upthread.

If you do a lot of highway work, you should see them last longer. But 30K seems to be 'average' life for 'average' city use with 'average' care.

However, if you use a pressure washer to clean your bike? Yeah, good luck, might not see even 15-20K out of even OEM bearings.

I've been torquing my rear axle to 50-55ft/lbs since LDH mentioned overtightening. I don't have the privelege to lift the rear all the time to get a proper torque by feel in. Plus I'd go OCD on it and keep loosening it to get a better feel on the next one.

Just a heads up...

If you go to "Helpful topics for 919 owners", under "Maintenance/Helpful How-to's" theres a thread on repacking wheel bearings...read it! If you do this when the bearings are still relatively new, and then periodically, they will probably last for the life of the bike.

Your rear sprocket mounts to a carrier. The carrier fits inside a rubber bumper lined receiver inside the hub of your rear wheel.
The idea is to lessen shock loads to the drive train.
