2016, 3500 Ram long box. Replace drive shaft with one piece?

It’s a pretty common mod, or used to be. I didn’t know they still were using some 2 piece shafts.
I did it on our 07 years ago. I didn’t have any extreme issues but being a stick shift, it tightened up the drivetrain considerably.
Worth it IMO

Check your U-Joints

If carrier is bad, replace the bearing. If you go with 1-piece, you will need heavier tube. More flex in u-joint will shorten life.

How many miles on the gear oil...? Could be the rear end..... I had a slight shudder, carrier was fine, changed the gear oil, nice and quiet.

Go to these forums and search. Plenty of info on what you are asking.

Is this taking off on a turn????

comes and goes with throttle??? vehicle speed or engine speed???

Vehicular speed.

Chirping on take off usually indicates a u-joint going out. Carrier bearing will often make a roaring sound similar to newer hub bearings. Strongly advise not to go with single driveshaft. It will need to be heavierand even if it is built properly...the extra length will cause the shaft to want to spin kinda like a jump rope and cause another set of problems. If you have a lot of miles on the truck...may be a good idea to have the other u-joints and the carrier bearing replaced at the same time.
