At the rearend, with the driveshaft off, move the truck so the yoke is up and down. Use the same method with the little piece of wood across the yoke and your angle finder on the wood. Again subtract 90 and it should ideally equal 3 degrees up.
You want weight on the suspension and truck sitting on a level surface. You can put blocks under the wheels like you said as long as they are all the same height.
The best way to think about pinion angles (with one piece driveshafts) is to imagine a straight line going from the center of the front pulley bolt and out the centre of the trans output shaft and continuing to the back of the truck.
Now imagine a line coming straight out the rearend forward. Those two lines should run parralell.

Just for reference I was playing around with my engine angle. I shimmed up my trans crossmember 3/8" and it decreased my angle about .7 degrees. |
bigmoe, Thanks for the reply and help on this ! that's a good idea with the straight piece of wood. Im going to try this tomorrow and get the reading off my engine pulley tomorrow, it would by nice for now, just to know if my engine is at least in the ballpark. Thanks for the link and your explanation of how to figure the pinion angle it all makes sense to me more and more now, the only thing is I was wondering if you put a jack underneath the tranny to move it up will that cause any stress on the engine or engine mounts ? going to check that link out now, again thanks for trying to help its much appreciated !
