Default Pinion angle
Ok so I don't think i have any driveshaft vibration but it doesn't seem as smooth as I remember with the stock driveshaft. Is that just common with aftermarket driveshafts? Here is my rear pinion angle. Let me know what you guys think

hard to say for sure just from looking at your pic but, if that's all i had to go off of, your pinion looks like it's dipping down a bit.

I agree that it's dipping a little down. Maybe 1 or 2 degrees. Would that cause a problem though? I drove jeep a mile without setting the rear pinion and had bad vibration. So I definitely don't have that now.

It's a teraflex 3", but I'm about 4-4.5" of lift.

Your gonna need adjustable control arms to get the vibration out.

I have those. It's adjusted now. I'm asking if 1 or 2 degrees off would cause a vibration?

Yes, short wheel base trucks it is more critical to have the pinion angle as perfect as you can get it.

Ok. Well it's not absolutely horrible. I'm on the road for a week or so. Hopefully it doesn't mess anything up too bad

Yes, but seems like I read perfect is 1-2 degrees below. I would say put it inline and see how it feels from where you have it now either leave it or move it back.
