0ne or two piece driveshaft?
Is there any advantage to either a 1 or 2 piece driveshaft?
I have a Short Wheel Base truck that didn't have a drive shaft. I know there is a place for a carrier bearing, but if I have to build a new Driveshaft, I want to know if I should make a 1 or 2 pieces unit. I will be running airbags lowered. LS power to come later.

My 70 C10 had a 2 piece and the center bearing rubber holder kept going out. If it didn't, the bearing would.
A friend said some of the trucks came with one piece. He found one for me and it was great. I really don't see why they ever used 2 piece in short wheel base. |

Re: 0ne or two piece driveshaft?
I'm not sure if there was actually a 2 pc in the truck, there is just the place to mount the carrier bearing.
When I swapped out my trans in my other 72, I ran a 1pc because I had the trans shop decide and they just modified one end of one they had laying around. Is there any difference in the pinion angle when running 1 vs 2 pc?

Re: 0ne or two piece driveshaft?
I have seen them both ways. I read that a lower geared truck benefits from the two piece. Stronger according to the article.. I shortened my own [two piece] when I cut down my long bed. Not a big deal but just a little time consuming. I wonder if the length of an automatic is one of the deciding factors.

Re: 0ne or two piece driveshaft?
One piece: fewer pieces to go bad, less complexity, easier to set the u joint working angles
Two piece: enables higher shaft speeds (=higher vehicle speeds) across longer wheelbases; smaller diameter tubing can be used to improve packaging Quote:
