is it a rule that both shafts u joints are at the same degree
is it a rule that both shafts u joints are at the same degree
Yes. If they are out of phase you will get serious, possibly shaft destroying, vibrations. The angles of the joints are as important and must be equal.
That's right. Apparently it will cause terrible vibration otherwise.
Edit: D'oh beaten (and with handy diagrams!)
Read this. It's worth it, no matter what you are building.

The first U-joint makes the rotational speed of the shaft uneven, and having a second one to "reverse" that corrects it and gets the rotational speed to smooth out at the other end.
In other words, the first U-joint berkeleys it- the second one needs to mirror that to unberkeley it.
so this shaft on my 2014 polaris rzr if berkeleyed up like everyone is reporting by they deny it....$20,000.00 and i have to have the sahfts rephased, motherberkeleyer
