Cool thanks I didn't come across that thread in my search I'm having that same vibration described on the thread. I figured I'll try the u joints first if that doesn't work then the front hubs.
I had a similar vibration too - tried new front hubs, rebalanced all tires, new trans mount, was told the trans output bushing and u-joints were ok. Finally went away on it's own...
I prefer the non greasable brute force u joints from advance. They have always worked well for me and it's nearly impossible to grease them in the car.

One more vote for non-greasable. I actually have to replace my u-joints this weekend due to one of the greasable ones going bad and causing a nasty vibration at highway speeds.
