pinion angle?

[rod]

there is no good place to place the magnetic angle finder on a 9". so I made a 5" tab, which uses 2 studs on the pass. side. now, I get 1 1/2 degree up.. so using a 4 degree wedge, I should get 2 1/2 degrees down.

will post real measurements when finished next week.

My way of doing it has the driveshaft out of the car. Car sitting on boxes so the chassis weight is on the tires. Have the pinion yoke turned so you can measure off of the flat of the yoke. Place angle finder on harmonic balancer, then place it on pinion yoke, difference is pinion angle.

Eman this is the simplest way to do it. Too many people over think it.

BTW: You can download the Tremec Driveshaft Angle Finder tool for your phone on Google Play...FREE! Useful at the track....or at the shop. Accurate to .1 degree...Works on Android systems..

That's the way John Calvert taught me.

Doesn't tell you the operating angle of the front and rear u-joints, which could be quite different car to car depending on location of engine/trans assembly, ride heights, length of the drive shaft, pinion height in the rear, etc.

I want to know the operating angles of both joints. Rare to have the desired configuration of the front joint near zero and rear joint at the desired number down (negative).
