The car is tall enough that I can squeeze under it to check the driveline angles without jacking it up any and the car was in neutral as well.You need to measure off from the u-joints/yokes.
81cutlass He is correct, with 2-2.5 degrees in either direction is not going to cause an issue. Be sure you are measuring with the weight the vehicle being supported by the tires and the car is not being held in place by a parking brake, gear or any driveline component. This is most easily done on a drive on lift.
Checking runout from the u-joints would indicate more runout from the pinion yoke/ trans output shaft than the driveshaft itself wouldn't it?
