Thanks for the response Jim. Since I've posted I've been researching my options and will need to come up with some more money before I can do anything...I haven't broke into the unit yet but here's what happened. When driving and letting off the gas I started to notice a harsh vibration coming from the rear. Over the holiday I had places to go and had no other means of getting there so I took the chance,,,Last night when I was a few miles from home I could hear this god awful grinding(from the rearend) on deceleration and assumed that it was coming from the rear axle. What will I need to rebuild this thing..I've priced a new set of ring and pinions with rebuild kits and they come close to my budget anything I'm missing? I'd also like to increase the ratio <img src="/forums/images/graemlins/scared.gif" alt="" />
