Say what?.......sure you did and I quote "for example, if the front joint is lower than rear joint, and the transmission slopes 5 degrees downward toward the rear and the pinion slopes 2 degrees upward toward the front"



If the front joint is lower, the driveshaft is most assuredly running UPHILL........if the pinion is ALSO pointing UP and these two rising lines meet, they form a point at the top correct?.......and you are telling me that is not POSITIVE pinion angle..........okie dokie then.

PINION ANGLE.....one more time PINION ANGLE is the relationship from pinion to driveshaft and nothing else. If the angle is like a teepee that's positive, if it's like a V that's negative

Quotes from Hot Rod Network...."Pinion angle simply refers to the angle of the differential’s pinion in relation to the driveshaft. But ask 10 guys about optimal pinion angle and a lively debate will ensue. To get a range of opinions, we spoke to several well-known and respected chassis builders about pinion angles"

"Pro Stock chassis builder Jerry Bickel assures us, “there is no mystery to pinion angle.” Setting the pinion angle is the final step in driveline alignment. The goal is to create a straight line from the back of the crankshaft through the transmission, driveshaft, and the pinion of the differential—under load. Due to the tendency of the pinion to rise under load, some angle must be present at rest".
