Just somethin to check out if your lookin to swap 8.8 in. From WF home page, not oregon, drop down to TJ jeep forums & then a few posts down is a very informative 8.8 info post & has some recomendations for where to get one already done ready to go in etc. Honestly I just pulled my destroyed 35 out & pieced together 2 parts rearends & got it back in the rig in an afternoon. Building the rearend is not to be tried unless you have right tools experience etc but the bolt in & out is easy. You gotta start somewhere learnin & better in your garage then on the trail if it breaks!! You can do it!!
