I have a 2008 Yamaha wolverine 450 and I have a leak at the rubber boot on the drive shaft. theres a rip in the bottom of the boot, I guess I scraped it on a rock. so its leaking an oil-like liquid. I think its just grease. Can anyone help me out with the process of changing the boot and maybe anything else I should be looking for. Im pretty sure I have to take the rear arm off, but how do you disconnect and reconnect the boot, also, what's insidethe boot? is there something I have to disconnect thats inside the boot?

 

I have the same problem, did you find out what was wrong and how to fix it?
