Getting ready to do my suspension work and was wondering if anyone had some alignment specs or what they've set their front end to and how well it worked. I heard set toe in to just a hair in from 0 and caster between 4 to 6. Does this sound right?

 

I've had the best luck with my toe set at zero. As for caster, somewhere around 5 degrees should do you fine depending on how high you're going.
Once you go higher, caster will be more of a compromise between it and pinion angle. You may have to fine tune it a bit to keep driveline vibrations to a minimum as well as u-joint wear and tear, and still have it handle like it should.
While you have everything apart, it would be a good time to make sure your ball joints and other front end components are in good shape. If in doubt, replace them. That will save you a LOT of hassle later.
Hope this helps.
