Re: 2 piece drive shaft to 1

Driveshafts can ring like a windchime at audible frequencies if they don't have insulation inside them. Many " driveshaft builders" don't stuff their shafts. To check your shaft you can wrap 5-10 layers of duct tape in the center of your shaft to see if the noise changes or goes away completely.
