In Da Faaaaaace!!!
I'm curious to what you find. I have the same issue as you.This may be my vibration issue. Time to double check angles.
After watching it a second time, I am not sure this is the issue. He talks about vibration during acceleration and load, and the noise going away when you let off the gas. I have the opposite. Never a noise till I am coasting.
I measured my shaft angle to be around 26*
When I lengthen my lower links I can get it to 19.3*
That is gonna be the best I can do unless I run 1-2* more pinion UP from parallel...which may be worth it?
