and the wheels in the back go wobble wobble wobble.....
so i am on my way homw tonite when i reach the exit off the highway about 1 mile from my place. as i down shift and switch lanes i suddenly have this wonderful felling like the rear tire suddenly failed! rear end went everywhere, bike went side to side and it scared the hell out of me. i pulled over to find the tire was fine, so i limped the half mile home. when i raised the rear tire it flopped to one side. after 45 mins of gentle persuasion and very colorful adjectives, i was able to remove the axle. it seems my right wheel bearing decided to desintegrate. now my fellow hawkers, should i: replace the bearing and seal, replace both bearings and seals, or replace the bearings seals and axles. the axle is not bent and only shows little signs of rubbing on the right side. any opinions, suggestions and anyone else who may have had this problem, feel free to speak up.....thanx guys.

When you see the price purchased at a 'bearing house' you'll want to put both wheel bearings and the seal in.
shawk rear wheel bearings are popular size #6204 x 2 $9 each
brake side dust seal size 30x47x7 $6
I ground an old bearing's outside diameter down to use as a driver for the new bearings.
(bearing’s inset on the brake side)
If the right bearing actually 'spun' and the outer race of the bearing is loose in the wheel. You'll need to shim it up so it's tight again.
This is a good time to remind folks to check, repack, or replace, wheel bearings during tire changes. Especailly the right rear as water tends to get into that one.
Did you see some rust Phil?

I would replace both bearings and seals. A bearing house is the only place to buy them, waaaaay cheaper than the dealer. I just put front wheel bearings in my Aprilia. Don't know what the dealer would charge as there is'nt one close to me but I got the bearing from a supply house cheap. The bearings were $5.25 each and the seals were $1.71 each. The rear seal on the SH is the same size as the front on my Aprilia.

DEFINATELY replace both bearings! When the rear wheel started wobbling, it put undo stress on the other bearing on an angle which it wasn't meant to endure. You can also get your wheel brg kit through All ***** Bearing at a much cheaper price. May even come with seals. When I order steering stem brg. kits, they come w/ seals. As for your axle, how much wear does it show? If it is significant wear, it will not have proper clearances where it rides in the brg, creating a loose fit. If it were mine, I'd replace it just for piece of mind.

Heat the wheel around the bearing and pound the old ones out.
I'm really surprised you did not see that the bearing was lose in the first place.. A lose wheel bearing will make some scary slop at the axle.

You might have to use a diegrinder and a small cut-off wheel. You'd have to cut the bearing race in two places close together, then break that small section out of the bearing race. If you or someone close has a compressor you can pickup a diegrinder and diamond cutoff wheel kit at Harbor Freght for around $30.
Take your time so you don't mess up the hub taking it out.

Re: and the wheels in the back go wobble wobble wobble.....
ok...so the guys in my retail shop were able to get my bearing out with little to no fuss with gentle persuasion from and air chisle. any body have any suggestions on how to install....i know a press is best, but has anyone used any other methods as i have tommorrow off and will not be anywhere near the shop, and yes, i am very impatient, i almost cried when the best time i could get was thursday for the bearings, so waiting till friday to install them is out of the question.

Had to put in a new rotor side bearing last night. Throw the bearing in the freezer, and gently heat the wheel right before hand. Mine almost slipped in, just needed a few taps with the rubber mallet. Got the bearing at the local parts house for $11 BTW.

If you don't have a heat gun you can leave the wheel in the sun a few hours in the afternoon to heat it while you have the bearings in the freezer 'chilling'

Oh, and I'm not saying to heat the new bearing. That would defeat the purpose of using heat. You need to heat the wheel to get it to expand more than the diemeter of the bearing. The wheel will expand more since it's made of aluminum and the bearing is made of steel. It's called co-efficients of expansion. We use heat alot in Aerospace to get press fit componets together.

"When you freeze a piece of metal you are running the risk of setting up condensation thus causing corrosion by trapping said condensation between the mating surfaces or on the bearing races. "
We don't have that problem in SoCal.....no moisture here!
I remember it in Everett though
A light coat of WD-40 and a clean rag will remove the water ....I think...
