Drive line bearring holder between the two drive shafts in rear slide toward the front when i punch the throttle. I thought it was because the shafts were rusty, but i greased it up and three weeks later it pushed the bearring right out of the rubber holder again. I'm thinking of putting a plate of metal on both sides or maybe just on the side its pushing it out. Has this happened to anybody else and how did u solve the problem? thanks, ... . reb
