wobbly rear axle

EDIT- I GOT THE PIC WORKIN

Hi - I've got a wheel where the axle has "wobble" in it. I can move it up, down, side to side, diagonally within the hub with my finger. I've got a pic at the link below. Also - there's a section outside of the hub that looks like a bearing surface...weird. At first I thought a piece was missing, but I'm not sure. Anybody?



Also...winding the washer-nut all the way down does nothing to alleviate this. The bearing-surface-looking thingy stops it far before it gets to the silver bearing shield. Missing/loose bearings maybe? I took the bearing shield in the pic off and looked at those bearings - those were fine, but i couldn't figure out how to look at the other side without taking the hub apart.



thanks

The link doesn't have the photo. Sounds like a broken axle.

I couldn't get it to load either, and then the site crashed my browser. Can you upload the image to the Forums?

Okay, well the first thing I notice is that the cone is on backwards, from the look of it. The cone-shaped nut that has the little path where the bearings have contacted it--it should be facing inward so the cone goes into the race that is holding the ball bearings. How did it get like this?

This might be a really good time to do a full hub overhaul and see what else might be out of place in there, check the condition of the axle and races and pack it full of grease, put in new balls, and adjust. It's the best way to learn how all those parts go together. Here's the Park Tool site link to show you step by step how to do this, or you can check a good basic bike repair manual for guidance too.

Someone definitely put that cone on backwards. Looks a real nightmare.

This has to be a joke.

No joke. Backwards cone makes sense considering it does look like the bearing surface on bb-spindles ive worked on. Taking apart a wheel (well...more like putting it back together) has intimidated me so far, but I guess this is as good an excuse as any to go try it. Thanks for the obseravations (as obvious as they may seem).

This would probably also explain why the bearing shield keeps popping off on its own.

Yes, your cone is on backwards! Hopefully it hasn't been ridden more than a few feet like that, because the unsupported axle and hub could easily be damaged by that.

Don't be intimidated about taking apart the hub... seeing its present condition, you can only make it better . If nothing is damaged, an overhaul of the hub should greatly improve things. You may need some new 1/4" bearing balls (generally 22 of them).

Mox - yeah there was some damage. It seems the axle was bent on one side a little bit - will probably throw a new one on later (I have about 20-30 of these old MB wheels).

For some reason I thought fixing this entailed taking apart the whole wheel - spokes and all. It only took me like 5 minutes. I love the feeling I keep getting when I learn how a new aspect of bicycles work. At first it seems so mystifying and complex, but then it's just a little nut here, a spacer there, bearings, and some friction. So cool.

Yeah, it *is* fun to learn how to fix this stuff! I thought a hub must be fiendishly complicated before I first took one apart. It's nice to know how to do it

You have twenty-thirty of these wheels and plan to "throw" an axle on this wheel later, yet stumble and falter when you are faced with the daunting task of re-assembling this hub. You even go to the trouble of pointing out that you can see what you think is the bearing end of the cone but you can't figure out that it is on backwards? Baloney.

Dude! The guy is *learning* ... when you're eager to learn things you're not always aware of what you can and can't do, what you understand well and what you don't. What's the point of telling people that they're hopeless?

Or the original posting was a troll.
