getting angles right

[85GMCJimmy]

How do you determine your driveshaft angles, in order to determing the degree of a shim to use. Where do you measure to get your 2 angles?

 

[Ryeguy]

Angle finder, off the pinion, should give the same # as off the T-case if you're not running a CV, or same (within a degree or two) of the driveshaft itself if you have a CV at one end. If you happen to get a driveshaft built with CV's at each end, don't worry 'bout it. :-)

If you happen to get a driveshaft with a CV at the front and a u joint at the other end, forget about it. I've never seen one with CVs at both ends. But anyway, if you do get a CV shaft, rotate the pinion up until it's directly in line with the shaft for the best u-joint life. If you do that without the CV it'll vibrate like crazy.

Big luxury cars ran driveshafts with CV's at each end.

Measure the angle off the pinion on the axle:

Make sure the angles match perfectly. Or no more than like 2 degrees difference.

I'm running the stock shaft and 5" of lift (lowered Tcase 1") and no vibes, until I hit about 75 to 80, but they're still not that bad. With that said though, I will be getting a rear 1350 CV shaft (HighAngle Driveshafts) after a few other mods

And yes, double sided CV shafts do exist!

Talk about pricey and over kill

But would be nice

Yeah Boss has the down low for ya. If you haven't dropped the tcase it will aid a lot in easing your vibrations.
