Some help needed here guys,

The front end on my 98 400 Scrambler was loose on one side. I opened the plastic cover of the wheel hub and tighten the nut. I also added a little oil. I thought everything was fine but today I noticed that is leaking oil on the inside of the wheel. The oil seems to be coming from the wheel hub. I lifted the wheel of the ground to see if if I had tightened the nut to much but thats not the case.

Suggestions anybody???

 

The inner seal may be bad. But it could just be a piece of trash in the seal also. Refill the hub and see if it leaks again. Sometimes when I play in deep mud the seal will leak after I wash the bike, but after my next ride it will quit leaking.

 

Same thing happened to me once when i was cleaning the brakes. Go to your dealer and get the end of the hub (where it says "Demand 4 Drive") It is just a plastic piece.

I think this is what you are talking about. If not this check your brake caliper to see if it is leaking

 

Count, I think your problem might be a little more involved than that. How tight did you tighten the hub nut?.. That specific torque is 8 ft. lbs. (100 inch lbs.)
If there is slack in there to begin with, I would suspect one of the four tepered roller bearings that are inside there.
When the wheel has slack in it, it usually means that there is a trashed wheel bearing. Its not difficult to disassemble. The parts are easier and cheaper to get from a bearing supply house. If its a hub bearing, you can jack it up and grab the wheel and try to rock it top to bottom or left to right... If its an Axle bearing, you will be able to move the half shaft where it goes into the strut tower.
