Driveshaft angles

Obviously we'd like to have a perfect alignment between where our driveshafts attach to the transmission and where they are inserted into the rear uprights.


How far is it reasonable to deviate from that?

I ask as I have a choice to make; Either:

1) Modify my "book" rear subframe which I've already completed or
2) Move the motor and transmission 2" forward, giving me a resulting angle of approximately 6'

Short answer: I don't know.

Longer answer: it's not black-and-white because it depends on: applied torque, angle, amount of time in that condition.

That said, since they're FWD CV joints, they're designed to handle extreme angles due to being connected to the steered wheels. Of course, typically there's little torque passing through them at extreme angles, which most often happens during parking or when making turns at intersections.

Summed up, I suspect they'll last a good long time - put your definition of what that is here :)
