Hello- I purchased an older gator but have had a great experience with it until my neighbor borrowed it. Upon return it had a clicking noise coming from what I thought was the middle wheel housing. I read around and came to the conclusion that it must be an axle. I ordered the parts removed it put in new bearings and axle and excitedly started her back up, only to find the same noise. It seems to be coming from the sprocket or around that area, but I can't figure it out and need help from someone smarter. Any help will be greatly appreciated. Thanks!
