i have a vibration that can be mostly felt in 5th. It started off as a vibration that only happened around 50-55. Now the vibration can be felt from 50-65 or so. It happens on both accel and deccel. It also gets better when i push the clutch in. I orginally thought it got worse when the car got warm but thats not the case. I just took a short trip and on the way up the road car was fine vibration wasn't bad. On the way back i got on the car hard got off it and guess what vibration was back bad push in the clutch and it wasnt so bad. Tranny is brand new and driveshaft is new also.

To sum it up bad vibration coming from the rear, can be felt in other gears but mostly 5th on acceleration and deceleration. Vibration gets very bad after beating on the car.
Any ideas?

Try the 4 bolts to the rear axle universal joint flange, which connects to the u-joint assembly and driveshaft. Those bolts somehow got loose on mine and the vibration was soooo bad, i tightened them twice and they kept coming loose so i put some threadlocker on em, so far so good.

I had a similar problem after gear install. The pinion nut wasn't torqued right. But not sure how yours would be loose if you haven't had gearws isntalled
