I found some articles on this and I'm gathering I need to match it up with a positive pinion angle (pinion up). Like in the image?

It makes sense until you put a bunch of throttle on it. I have an inline six and the springs are beefed so I don't think I'll be getting any wheel hop soon.

If you can follow this logic then you can fix any vibration problem.
