Good suggestion. I can try that. I need to remove the driveshaft anyway and try to get a good measurement on the driveline angles. I was having a really hard time getting good measurements. I need to be able to use the back of the trans and the pinion yoke.

The only thing I would note is that the DS was never removed in all of this lowering and pinion angling. So again, unless its just more sensitive to it now in its lowered state, Im not sure why it would shake specifically because of the DS.


I guess this could just be a reason for me to break down and buy a gear vendors kit. Lower that RPM on the highway lol.
