What Does Pinion Angle Do to the Suspension?

Pinion angle doesn’t directly drive suspension motion it’s not a geometry setting like control arm length or spring rate What it actually does is set up or fail to set up a clean phase relationship between your two U joints and that relationship determines how much load and vibration your suspension links…
