      4l80e Lube problem

      Hello, I have a pretty new build with a 4l80e that I rebuilt and changed it from a 4x4 to a 2 wheel drive. Car has 800 miles on it and cruising down highway at 80 mph car started vibrating bad. Raised up on hoist and tail shaft bushing is destroyed. Had a new yoke and bushing. 4l80e trans also have an output shaft seal. Is that seal supposed to be removed when converting to 2wd to get lube to rear tail shaft bushing? I called place when I got trans kit from and they said to drill hole in output shaft seal. Just wondering your thoughts or ideas or if anyone had same problem? Thanks Kris
