Aligning pinion angle for perches
I'm in the process of aligning my pinion angle. Simply lining up to point the rear pinion is more of a chore than I thought or I'm trying too hard. I know I want '0' degrees from my rear pinion to my driveshaft angle (double cardan) during operational loads. I'm going to eventually install an anti wrap bar. So I'm going to install it at '0' degrees for now and add shims for 1-2 degrees down until the bar is installed. And yes, I have the the on the weight on axle.
My question: what have you used to do the alignment? I want to get this dead nuts. I've read where people have used a protractor. I can see where you would need one for single u-joint configuration. But simply pointing the pinion at the t-case output seems to be an eyeball judgement. I'd rather be precise. How much room for error do I actually have? I have a laser, might try rigging that up I guess.
I've installed the driveshaft that's going in at the t-case, (needs to be cut down). I then installed the old driveshaft on the rear pinion and try to get them parallel (what a pain). I've thought about having the drive shaft cut down, install it, and then set my angle. Thoughts?
