I removed my carrier to put in a posi carrier. Do I need to check to see if the ring gear is centered on the pinion since I never had the pinion gear out. The way I understand it is to just set the backlash to .008". Any opinions on what I should do

Just swapping the carrier and setting backlash should do for you.

It may make a little noise if you are a little tighter than it was, but should wear in on a good run.

However, be sure to run a good name brand additive if you have a clutch type posi, and you probably should start with a few slow and gentle figure 8's and circles
