I have a Yamaha Timberwolf 250 2x4 that I purchased a while ago as a project. I fixed it up to where everything was working great in my opinion, however when I showed it to a potential buyer he complained about a vibration from the rear drive shaft. (Which I ridiculous seeing as he tried to wheelie it before that) Anyways I took the rear diff apart and found most of the seals and bearings where bad. So I bought a kit off of amazon only to find that it doesn’t have all of the bearings and seals. After finding that I decided to try to find a used good condition replacement but they’re all to expensive for me so is there a better alternative for me, or can someone point me in the right direction to get the rest of the parts?
