The how2 on replacing the CV boots is in ... wait for it ... the how2 section. It's Billy's write up but I converted it to pdf so that you can print a copy to have handy during the install.

There's also a write up on installing diff drop brackets there too. This one was written by StarChild from an Isuzu forum but I converted that one to pdf as well.

Both are jobs that you can do in your driveway if you are willing to spend a full day at it and don't mind getting really dirty.

My lift was done by the PO. I'm pretty sure it's a full 3" in front. It put my CVs at such a harsh angle that the half shaft was almost touching the outer race. It's no suprise that the CV boots can't handle that bad of an angle. I was killing CV boots about every 6 months till I dropped my differential 2". I haven't had any problems since.
