Hello I'm trying to fix the 4 wheel drive on my quad bc the splines on the middle driven shaft and the coupler gear got ground down. I've never done something like this so I'm learning as I go, I'm close to getting it out now I've got the back end stripped down to the bearing then there is an oil seal i think right behind it then on the front end i just got that bearing retainer nut out so it's just the bearing and a collar wedged between the shaft an the housing. So I'm not to sure how to go about the next step if anyone can help me out it would be much appreciated??
