Pinion angle

Hey guys quick question regarding pinion angles. I have no technical way of determining the actual angle so I hope a photo will help. Just installed SS and trying to set angle to measure for new shaft. Am I close? I can try to take different pictures if this one isn't very telling.

It's close enough to measure for the driveshaft. Get a magnetic angle finder to get the pinion around 1 degree lower than the driveshaft after you get it.

Install the new driveshaft which will make setting the pinion angle easier to do since you'll have a better visual of the DS vs. pinion angles.

Just remember the pinion shaft is at the right angle if it points directly at the t-case output shaft/CV joint.

Should look like the first illustration below.

The next photos show how you can measure the angles. The angle finder at the rear of the axle housing shows a good way to measure the pinion angle which is exactly perpendicular to where the angle finder is measuring from. Flipping the angle finder as shown gives a direct pinion angle measurement.

Thank you Mr. Bransford.

I was also wondering the same thing about driveshaft angles.Is there a spec to go by so If I were to put one of those magnetic angle gauges on the rear driveshaft I could compare to?

Should the pinion point towards the transfer case output or towards the universal joint closest to the pinion? I'd imagine that's two different angles.

The angle needs to be the same as what ever angle your drive shaft is.
