I've had an intermittent high speed vibration for quite some time now. While I was under the car screwing with the tank last time, I noticed some play up at the trans in the driveshaft. Today, I yanked the tailshaft housing to install a new output shaft bushing and seal. Wouldn't you know, I smacked the seal driver too hard and knocked the little spring off the inside of the seal. That was fun! I got it back in there, though. Does this look a little wore out?
