I have decided to get a new drive shaft. I have narrowed it down to two options. 1. A two-piece CV shaft from High Angle Driveline. 2. A one-piece 5 inch diameter aluminum shaft from CCI Ford Super Duty Monster 5 Aluminum Drive Shaft Upgrade - CCIDriveline.com and eliminate the carrier bearing. The truck is a crewcab shortbed with 5.5 inches of lift, but I may go to 7 inches later. Anybody have any experience with either shaft?
