Pinion angle with Monoleafs and CalTracs

The rear pinion angle should be set so that when you accelerate really hard the pinion angle should be the same as the drive train angle. When you accelerate the pinion rises up, if it rises too much (this depends on how "stiff" your rear springs are) it will cause problem. If it doesn't rise enough it will also cause problems. In other words, if your engine drive line is ZERO (perfectly level) you would want your pinion at ZERO when you're accelerating real hard. This aligns the front and rear U joint. You also have to make sure that the U joint phasing is correct??

If your drive line is 2 degrees down then your pinion should end up being 2 degrees down during "hard" acceleration..
