OK HERES MY STORY...I WAS JUMPIN ON MY 300EX TODAY AND EVERY TIME I GOT IN THE AIR MY BACK END WOULD START WIGGLING REAL BAD. THEN I HEARED A PING NOISE. I GOT OFF AND SAW THAT SOME CLAMP WAS JUST HANGIN THERE IN BETWEEN THE SWING ARM AND THE BRAKES SO I DECIDED TO TAKE IT HOME. I GOT IN THE ROAD AND FIRED IT UP AND WHEN I HIT 5TH THE BACK END STARTED WOBBLING REAL BAD. SO WHEN I GOT HOME I PUT IT UP ON BLOCKS AND WENT THROUGH 1ST 2ND AND 3RD GEAR. IT DIDNT LOOK LIKE THE AXLE WAS BENT SO I TURNED IT OFF. FINALLY I GRABBED MY TIRE AND STARTED WIGGLING IT. EVERYTHING (EXEPT THE SWING ARM) STARTED MOVING REALLY REALLY BAD.
WHAT SHOULD I DO? WHAT CAN I DO WITHOUT TAKING IT TO SOME HONDA SHOP?

 

You did not state the age/condition of your quad, but it sounds to me like you have a worn out carrier housing or bearings. You can purchase a kit to rebuild it or tear it down and buy the needed parts from your local dealer. DO NOT RIDE THE BIKE UNTIL YOU HAVE THIS FIXED. I know I am stating the obvious, but you would be surprised at the things some people will do without regard to safety or the damage to the quad they are risking.

 

Shumdit is right I did the same things about three weeks ago I had to bye bearings and a rear sprocket hub I think that is what it is called the bearings was $300 and the hub was $140 and I when't ahead and bought a Durablue axle. the axle is coming toworrow. By the way I have a 400ex

 

I too agree,I think you need new bearings for the tires.I also agree,DONT RIDE IT.Im sorry but unless you are a mechanic you will need to get it to a shop.Here's a tip,dont take it to a big Honda shop,Take it to a smaller one and it will be quiker and less expensive.Good luck!
