Uggh, what I figured. I want to replace everything that needs replacement, but I can't afford a new diff right now. Is that kit you're referring to specific to certain gear ratios? Should I inquire with an Isuzu dealer? If so, which one is recommended to buy from? I'm trying to get this done as inexpensively as possible right now, but of course I want to do it right. I also don't want to end up replacing something that I am going to replace if I put in a locking or PosiTrac diff.
