what do you measure to find out the rear end angle?
do you measure the angle of the driveshaft and the pumpkin and subtract?
where on the rearend do you put the angle finder?

thanks for any advice you can give me,
Michael

I set pinion angle off my j bar mount on the flat part on one side or i use one side of the pumpkin across 2 studs with a protractor level.

we always just take the drive shaft out and stick a magnetic angle finder to the yoke

5 to 7 deg is the rule of thumb.

We put a socket on the rear u-joint cap when the pinion is straight up and set the angle finder on that and run about 8 deg.

Our Harris car calls for 7.5 degrees.
The DirtWorks guys had me run about 9 degrees In their car.
I bought one of those digital SMART levels for pinion angle. Real nice unit until I needed to recalibrate it.

I just put the angle finder up against the flat bottom of the rearend housing.

Are you setting the angle with the car on the ground or with it jacked in the air? I would think it has to be done on the ground for a true reading. Unless you jack it with the pumpkin and don't use jack stands.

I check mine with the car down on the ground and with the drive in it

Yep, the car has to be at the correct ride heights to set pinion angle.
