This Jeep had spent much of its life in Boone, NC, so it had a decent amount of surface rust underneath. No frame rot or rust on the tub, luckily. I am a bit OCD about my undercarriage and like it clean and nice. My dad and I put the Jeep on a lift and power washed, sanded, and repainted everything underneath. I forgot to get before pics, but here's now it turned out. The specs are dirt from driving home when it was raining and muddy out.
I soon noticed in the first pic, that my crappy stock tie rod was bent. Go figure. Time for an upgrade. Since I didn't really have a good idea of what my future build plans were going to look like, I decided I didn't need to drop a couple hundred bucks on HD steering, like Currie, etc. Did some research and decided on the ZJ V8 tie rod swap. At a fraction of the cost of other options, it was a great deal and is a VAST improvement over stock. I also did the V8 tie rod ends as well.
During the washing and painting of the undercarriage, my carpet got soaked because the PO left the drain plugs out. Instead of letting my Jeep smell like wet dog, I pulled the carpets. They are still sitting downstairs in the house to this day. I plan to do bedliner (Monstaliner) sometime in the future.
