Hello everyone, new guy and 1st post and in need of help. I just purchased a 2000 2x4 gator at a very good price because the left rear hub axle and sleeve were stripped out. The axle shaft coming out of the trans looks great on both sides. I'm assuming the previous owner had the differential locked in all the time or on concrete.... So for a quick fix just to see how it runs before I put money into it I switched the right hub (good one) over to the side that was stripped out. I had it jacked up and put in gear and you could hold the tire in place with little effort while it was in forward or reverse, unless the differential was locked in then it would turn like normal. I checked the obvious.. linkage, oil level in trans and everything looked good. So being a natural take apart and fix it guy I pulled the trans to have a look. To my surprise everything looked really good besides the smaller gear that the chain hooks to had a little wear on the teeth that the shift collar slides over. But the trans shifted fine and that doesn't go with my man drive axle problem I don't think. I have not taken apart the differential gear assembly but as far as I can tell it looks fine as well... Anyone have any ideal of what could cause this issue? Or can point me to what to look for in the differential assembly that could cause this? Really wanting to get this gator up to par and drive without having to lock in the differential because I will never use it anyway. Thanks in advance and look forward to finding out the problem. If I'm unclear please let me know and I will try to explain this issue better.
