I had to put nutserts in for all 6 of the skid bolts. All in all, the job wasn't nearly as hard as I had feared. I followedLink to the exact nutserts I bought: McMaster-Carr I bought ones that were for metal too thick. You may want to find ones for thinner material (McMaster has them.) Link for the lazy: McMaster-Carr I used this guys writeup: Nutsert for Transfer Case Removal and Install - JeepForum.com . His tool worked a charm, I didn't drill out my nut, I just used one big enough to spin freely. If you have an impact wrench handy...use it to start the crushing. The first two I did completely by hand and they wound up a little crooked because the force of the wrench wasn't even. The impact crushed it directly down. DO NOT USE THE IMPACT WRENCH THE WHOLE WAY, you will ruin the nutsert. Just use the impact to crush it until it tightens and then do the rest by hand.Full complete side:Some of the mess the PO left, cleaned up some and sprayed with rust stop. The rivnut is covered in threadlock:Skid before I cleaned it up and spray painted it. Sorry no photos of that.Both of the middle holes in the skid were rusted out. This one was way worse. Something I'll have to deal with soon.
