What is tha max angle the drive shaft can be in relation to the yokes before the u-joints begin to max out, or get an RPM wobble.(you know when the drive shaft and yoke RPM's fluctuate because of the u-joint angles)
well you should never get near max angle when you are at speed unless you are jumping it? I believe 1350 u-joints are maxed at 30deg. 1310's got 35deg. I have seen tom's cv shaft advertised as going 80deg. but that is a very severe application that probably has a low u-joint lifespan.
