Hey thanks I guess this weeping hole leak shit is pretty common in these bikes I bought a new case an Impeller thinkin that would work but it didn't so I realized there's play in the impeller shaft which means its a bearing right? So I bought a bearing and oil seal and the other seal

Yeah, I replaced the seal, shaft and bearing on my '06 twice and did it on a friends '09 once. I am sure it is best to replace all the peices at once. It is not hard and does not take more than an houre if you use the manual.
