Thoughts on single piece driveline on extended cab...

You cant just put the blue coated male end with a slip yoke not designed for it. You got screwed by a driveline shop that OBVIOUSLY doesnt realize that billions of driveline were made before that blue ****.

"Critical speed" is why we see large diameter aluminum driveshafts on newer trucks with long single piece driveshafts. Proper driveshaft design has a critical speed (rpm) that is well over the max RPM of the driveshaft.

The longer you make a driveshaft with a fixed diameter, the lower the critical speed becomes. A large diameter aluminum or carbon fiber driveshaft is needed for the long driveshafts.

A carrier bearing allows the use of a smaller diameter mild steel shaft, keeping costs down.

Yup. Thank you. I appreciate someone who really knows backing me up. Just irritates me that I paid for them to screw it up.

It’s together for now and unless it gives me problems, that’s how it will be.

Tom Woods built the shafts in my Jeep. He's a great guy and imho, the last word on driveshaft knowledge. Any doubts about what you are doing, give him a call. In my experience, he has been happy to give advice with nothing more than a thank you in return.
