I started noticing a vibration as I was seeding in 3rd gear. But the vibration only occurs under a very mild load. In the low range, in any gear there is no vibration. When I got out on the road to go home, I started out in 5th...no vibration as I have to climb a pretty steep hill to go home. At the top of hill I shift into high range and the vibration is back once I get it wound up. Input shaft bearing or one transmission shaft bearings? Which do you suspect? It feels more like a rumble so I think its a large ball bearing but I figured I would ask to get some input too.
Thanks
