Tranny and diff. leak.

A few months back I installed 4.56 gears and I really like the result. My only concern was vibration (bad vibration) at around 80 mph and above and when I was coasting at about 60 mhp down to 40 mph. Some say I need to get the driveline balanced. Wouldn't the vibration happen at a certain rpm and not a certain mph? I don't know for sure but it kinda makes sense to me. On top of that I was driving down the freeway today and I noticed smoke coming from my truck. It turned out that the tranny was leaking fluid from where the driveline comes into it because the seal was working itself out and the fluid was leaking on top of the exhaust causing it to smoke. When I got home I got under the truck and noticed that there was fluid sprayed or flung all over the under carriage around the rear differential too but I couldn't detect where a leak that could cause that was coming from. Can anyone help?

You probably need to replace the rear seal on the tranny and the front seal on the pumpkin. The vibration issue I'm not so sure about. A number of things could cause that but in your case ujoints?
