At first, i thought it was caused by the rear end, but when I drove it again, it was obviously coming from the front trans area.

Makes me think I either got the flywheel in there out of balance or maybe the transmission.

I’ll try and take a video tomorrow.


I've seen starter drives gears make contact under acceleration due to worn fork, etc.
