Hello I'm a newbie here I don't know if I'm writing this in the right spot I don't know really I ain't never been on nothing like this before but anyway I have a 2004 Jeep Grand Cherokee I don't know I'd like to know if that's a WJ or whatever what what it is cuz I keep hearing about that and I don't know what it is but anyway I am having some real issues and I'm going to replace the whole rear end
assembly and I've got questions about that I know a little bit about my vehicle but I don't know as much as y'all do around I don't work on it but I would like to but if y'all could please help me make like the decision of what you get so that be the 3.73 if I get it if I took what you all said right but I really like to have you all the opinions I've never dealt with any like thing like this before you know I can change my starter and I can do the serpentine belt like the little stuff that this is pretty in-depth for me and I'm pretty much on my own with it and I'm pretty confused and I'd appreciate some input here and I appreciate y'all's time and thank you
