I did mine with all hand tools. I didn't have a vise to do the ring gear so I made something out of 2x4s held down with C-clamps on a bench to hold the diff case when torquing them back down. Other then that, it was all wrenches, ratchets, small crow bar and hammer.
That IS a really great writeup! I'm still a little pessimistic - nearly everything I've read about autolockers is that they're not good for DD TJs. Too much noise, clicking, chirping, etc. I live in FL, the land of the U-Turn, so that's a concern. BUT, this isn't a project that I'll get to before next year, most likely. If installed in the front as in this example, safe to assume I'd still deal with the noise even when in 2WD?
I wouldn't worry bout the clicking. I live in Germany right now and my tj feels like a monster truck on some of these narrow streets. The clicking doesn't bother anything on my rig when I navigate on the streets here. To be quite honest it is rather funny to see the Germans looking at me like I'm driving on a front diff that's sounds like its gonna break. You should be just fine driving there in Fl. You will barely hear it in 2wd when ur cruising. Only time I notice mine is in a parking lot, etc. if it clicks too loud I just turn up my radio!
