That's strange since from my understanding these issues are actually what a 1 piece shaft is usually installed in Mustangs to alleviate. The Mustang 2 piece shaft with the carrier bearing has a MPH limitation and it's known to vibrate from failed carrier bearing bushings sometimes even in cars with lower mileage.with GTOs there seem more draw backs then positives . From limitation on MPH, and RPM to vibrations in the drive train.
First off thanks for your response. This is what I’m looking for as far as information. I know that each manufacturer is different so the reason I’m asking. It’s been a long time since I’ve have a Ford so getting reintroduced to the product and learning the Dos and Don’ts.That's strange since from my understanding these issues are actually what a 1 piece shaft is usually installed in Mustangs to alleviate.

Yeah the pinion angle is something with these solid DS that can destroy them easily. I had to pitch mine by 14* on the GTO for it to run right and stop the vibration I was experiencing. Thanks for the heads up.Sure, have heard of problems with that swap. Had friend driving out to Track Attack in Las Vegas (sp?). Just put in new one piece and it was shot by time he got there. Can’t recall what was re-replaced with- think went back to 2 section. Something about too much pinion angle going straight from point A to B?
I think the 2 piece is a cost saving part. They are made of steel heavy and cheap. The lowering is a big issue with solid DS. My GTO is lowered, lowering springs in back and coil overs in front. Another reason why I had to adjust pitch angle. I’m going to have to research this because I do like the lowered stance on cars, and while I’m not going to go crazy on mods. I like the throttle response and transfer of power you get. But I’ve played the high HP game with my C5 and the more you make the more you break. Not doing that with the 5.0.in the earlier years (S197 2005-2014) the one-piece driveshaft was mainly to eliminate the rotating mass of the factory boat anchor driveshaft, and the losses caused by the extra joint in the middle. On the other hand, the factory driveshaft was usually a lot smoother and easier for pinion angle adjustment; because the driveline angles in the S197 are screwed up and that extra joint helps to make the whole system more forgiving.
In the S550 chassis, I woulda thunk, that they woulda fixed the drivetrain angles and the two-piece driveshaft would not be needed ... apparently not.
So, the one piece driveshaft does save weight and reduces drivetrain losses, but the pinion angle becomes more critical and other changes like lowering the car can throw it off.
