1985 bmw e30 325e witha bad rear u-joint in drive shaft making vibration/wobble in second gear while on power. What you see is the center support bearing which is where the vibration is felt. The rear u-joint locks up as a slight angle and essentially "kinks" the drive shaft which then leads to an out of balance condition. fFor the longest time I thought it was a bad center support bearing, but it turned out to be the driveshaft. One used driveshaft later, it works like a champ.
