Well, i found out 2 weeks ago that my rear bearings needed to be replaced. I have not ridden it since I found out that the bearings were messed up. Well, today since I had some free time and since I had the parts I thought that I would replace the bearings myself. I pounded on the axle for 15 minutes before I gave up. The axle simply will not budge. It did not move even a milimeter. What did I do and what do I have to do to fix it? I may have ridden it for a while on bad bearings. I am not really sure about that though.
