undercarriage w/Downey springs/shocks. AutoZone has Rust-o-leum rubberized undercoating on sale this week 2/$10, so I foresee several hours underneath on my back rustproofing the undercarriage. That's the original spare, too... 1992 Goodyear Wrangler never been used! I added air to it but it really should be replaced. It's almost 20 years old! The next time I'm at the junkyard I'm gonna find a '90 or '91 spare tire cover to wrap around my spare. The steel rim is showing signs of rust. and, oh yeah, that is the original 1992 toyota tow hitch receiver cap or whatever it's called. I pried it off, cleaned out the dirt and rocks, put a small dab of white lithium grease around it, and its as good as new. Also, I cleaned out the corrosion from the trailer electrical connection (Q-tip and metal cleaner)
