so i finally got time to tear down the rear end. first thing when i drained the gear oil it looked like someone took a bottle of silver glitter and dumped it in the gear oil, there was so much metal in it. once got everything torn done everything seemed ok, the one bearing on the gear case side seemed like it had a little hang up in it, other then that everything came apart pretty easy. the only problem i am having now is getting the lock nut out that holds the bearing in front of the pinion gear. seems like i need a special tool to get it out because the lock nut is in the shape of a star which i can get no tool in to take it out.
