So I have a 2000 blazer. I have the infamous sun gear blow out. I have a 1999 jimmy that I have as a donor. From what I've read everything is the same. It should just drop out, and bolt in the other truck. Am I correct on this? Anything special I need to watch out for? I've seen a couple videos on youtube, it looks pretty straight forward with minor cursing. And does the exhaust really need to comoe off? Thanks in advance for all your help
