Good day all,
I am trying to figure out what would necessitate the lowering or elevating the position of the senter bearing to eliminate vibration. I have installed new engine mounts, transmission mount and the center bearing but still suffer a vibration coming out of a stopped position. I initially felt I had concoured the problem until I gave a gentleman I work with a ride. It seems the added weight brings forth this problem, he was a bit larger than myself. I am wondering if the issue stems from tired bushings in the rear suspension or a imbalanced drive shaft. It appears the drive shaft has never been out of the car so I question imbalance and the slip yoke is keyed such that I could not have erred in reinstallation. The tips your site offers is to either raise the center bearing up or down, my question is does my symptoms determine which way to go?
thank you, phil
