Bad vibration

Bad universals or drive shaft out of balance.

Brand new Moog u joints. I just had this driveshaft made. I told him I wanted it balanced. He said it is a seamless shaft and they are very true. He would be more than happy to send it out to balance, but he was confident I'd be happy without balancing. It's not like he's a shoe. Mark Williams bought him out years ago, now he just does side work.
