I have 500 miles on the new gears and have been very happy with them. I need to change out the gear oil in them now. I had a vibration start to develop that made me very nervous that I had messed something up. After inspecting the driveshaft I think I found the problem. Trail Fail parts out. Trusty Matsuba U-joints back in. Hopefully this was the entirety of the problem. If you dont have a U-joint puller and a c-clamp in your trail tools, I strongly recommend adding them.
