HAs anyone had the problem w/ the rear end and front differential blowing gear oil back through the breather tubes? Then it runs down into the air box. Did I put to much gear oil in when i changed it. I even noticed the oil to have a creamy look to it. Is there water getting into them? How would I know if I have a bent axle?

 

If it is creamy looking you have water in your pumpkin...That will cause the rear end to heat up and blow out the vent tube. Water can get in a few different ways:
1) seal behind the brake rotor
2) seal at the other end of the pumpkin
3) the connection between the pumpkin and the swingarm---seal with RVT..(this is where mine was leaking)- If there is any rust inside the swingarm this is where the water is coming from..

To check if the axle is bent -- put the quad up on blocks (front and rear) spin the wheels and if they dont spin straight try a different wheel on that hub(make sure it's the axle and not the wheel).

I have had the same problem as well. I found out that if I ride easy for a little while and get the gear oil warmed up then I don't have as much come out of the breather hose. You really can't tell if the gear oil is milky from the breather hose. You will have to drain it out of your differential to make sure. The reason it looks milky from the breather hose is because of all of the air bubbles in it but when you drain it from your diff. you will be able to tell really easily if it is milky. If you look to see if the axle is bent most of the time I have heard it happens on the left side where the largest part of the axle is exposed. At least that is where both of mine bent. You also probably need to check and replace the seals on the back axle. If you catch it in time your bearing might still be ok. You can take the seals off of the bearing very carefully and repack but make sure you don't bend the seals that go on the bearing so that you can put them back on after you repack them. I hope this helps.
