Just seeing what could be wrong or how water got in front hub.. I replace front a arm few weeks ago I hit stump bent a arm.. Could I have done something insde the strut where a arm attaches to ball joint.
I did notice my plastic front hup cover leaking a little could water and dirt gotton in through there.. Any ideas or help would be very greatful. Thanks It is a sportsman 500ho 2001

 

You could have damaged the hub seal when removing it or reinstalling it. Does the hub leak fluid at all? Possibly some dirt stuck around the seal

 

Yeah BBS is right, you probably didn't get them back in correctly or something was bent(like a seal or something).....I wouldn't think it could leak in water without leaking out fluid though, so look around.......

 

Which seal you talking about the black round ruber one that is on the plastic hub cover

 

I don't know too much about your quad.....but I would think it can only leak in two places.....on the inside(towards the radiator) and the outside(towards the wheel)....but maybe I'm wrong.

 

Im talking about the big black rubber one on the back side. That is most likely where it would be leaking from. The seal on the hub cover is just an o-ring and cant be replaced cheaply and easily. Teh big main seal is a little more involved. Fill it up and check for hub fluid on the back sid of the rim

 

What year is your quad? I am not sure what year they changed the front hubs from the style the 6x6 still uses. If its the "old" style and the hub is leaking all you need to do is to remove the hub and have a new seal installed. Its an easy fix and has to be done every 2-3 years. $20 tops for the seal.
