Re: Driveshaft opinion
The one piece is desirable since it is more durable and less maintenance. Two piece driveshafts were for heavy duty trucks that could reach higher speeds with the bigger engines they had so two peice was don't to keep down critical speed ( the speed in which your shaft turns into a jump rope).
The longer the driveshaft the lower the critical speed, the bigger the tube the higher the critical speed.
Say I put 5:11 gears in a long bed crew truck with a long driveshaft and proceed to drive as fast as possible on the highway. Well you would see some serious sh!t!
The weakness of the two piece is that two peices are not as stable at high speed anyways and the carrier bearings can't hold much.
