the vibration happens in straight line while accelerating. Everything is perfect when im popping a u-turn. Basically only happens when theres stress on the drivetrain. As far as I know a bad LSD will lock up on turns, so this drives me to think it's not my LSD. Last night I inspected my drivetrain, and found this on the rubber thingy holfing the driveshaft to the tranny:
it is probably not causing the noise, but i should brobably get that changed out.
