I don't think it would really matter whether they're toward the front or back. It's probably like a washing machine inside the u-joint ball when going down the road. Oil is going to get everywhere.
If you turned the cross (what you're calling a trunnion) around, then you moved the worn surface to the opposite side. That might have initiated the vibration.
Since you have it apart, a u-joint rebuild kit is a good idea.
