Everyone I've seen do it uses those angle finders, I did it by eye but I ran out of adjustment before getting it right so it's a moot point. Going to make some mods to hopefully get me there :twisted:.
If you have a double cardan joint in your front axle at the transfer case side.
You want an angle which puts your front drive shaft to front (axle side) yoke as close to zero as necessary to get rid of vibes.
If you have a single u joint at each end of your front axle
Your yoke to drive shaft angles should be the same at both ends just opposite directions.
All measurements should be done at street ride height.
it's not easy to measure and I have not been very sucessful at it myself. If you need further details on that perhaps some of my fellow jeepers could fill you in.
By eye I have been able to mostly get rid of vibration however once I put some more adjustment in it I will be using an angle finder to fine tune. You'll probably find a range that gets rid of vibration, within that range get your caster as best as you can. A socket on the u-joint cap might provide a flat enough surface for the angle finders (got to keep rotating the drive shaft to get the caps in the right position).
Proper caster is a nice thing to have but driveline vibration is first priority (u-joints and straps don't last very long otherwise).

Off to Home Depot, (with Pics) just so I can prove to them they have this(or not)!
Great topic Kakirubi.
This post will save me more than a few headaches, I'm sure, seeing as how this is my first lift install. You guys rock!! Say good bye to low- slung, teenie-wheeled ZJ March 1st.

Got it!
In Southington's Home Depot, they're in the tool crib next to the stud finders. Interesting though - they don't show up in their computer, no sales associate recognized the photo of one, yet - there they were, on the rack!! Good help is SOOOOO hard to find.
If anyone else needs one of these,Home Depot carries the 'Empire - Magnetic POLYCAST Protractor, #36, sku#15812 00036', if that helps narrow down the search.
