: I keep experiencing a vibration in my car while accelerating in 2nd gear from 2-3K or so. I was able to reduce the vibration by replacing the rubber u-joint (guibo) but it hasn't completely gone away. There doesn't seem to be any vibration during steady cruising at any RPM.
It could be the "flex disk" between the tranny and the driveshaft. I am in the process of replacing mine now for similar reasons. The rubber wears and cracks with age.
