How do you correctly find pinion angle with a 2 piece ds? Reason I ask, i have 4" drop from shackles and hangers in the rear. I also pulled the middle leaf to finally get her to sit level. I feel my pinion angle needs to be adjusted to help aid in traction. What is the correct way for me to find out what my Pinion angle is along with what my desired angle should be?

 

Really? No one?

 

measure the angle of the slip yoke on the rear driveshaft and measure the angle of the diff. the angles should be opposite of each other

 

What is the desired angle? -2*

 

No.That is only relevant for straight line racing under hard acceleration. That's not good for daily driving.

The pinion angle and tran shaft angles need to equally offset.

I've seen a good article addressing the OPs 2-piece drive shaft, let me see if I can find it.

Typically, you want the angles at the trans and pinion to offset.

 

You need to consider all your angles, not just your pinion angle. Make sure your u-joints have at least a 1* working angle so they don't burn up. Take measurements between the trans output, driveshaft, and rear yoke.

 

How about the carrier bearing and the way it's mounted? Mounted to keep 2 pc driveshaft straight with NO angle on it?

 

That video explains it clear as day. So you want the front and rear working angles to be the same? What is the desired working angle for a Silverado? What should be my target angle?
