Upper Tailgate Repair on a Range Rover Classic, Part 1 (Post #671) 9/15/2024

Yeah, yeah, I know, “I thought you were working on the floor bed?!?”

I was, but I looked at the upper tailgate and I know it’s gonna be hard to believe, but I found RUST! Shocking! Anyway, I thought I’d investigate and my OCD took over and then I was halfway through with taking it apart.

So what’s wrong? The inner tube of the lower frame is rusting BADLY from the inside out. Lots of surface rust on the outside but also rust has eaten through the steel inside out.

Do I have any hope at all that I can save it? A little, at least I’m gonna slow it down. This is one of those parts on a Range Rover Classic that rusts. Check the message boards…everyone has rust on their tailgate.

IF you buy a new upper tailgate protect it from rust immediately, do not pass Go, do not collect $200. If you don’t you will lose it to rust.

So the plan now is to paint it, I already have two coats of primer on it. The second is a daffy plan to pour rust preventative paint down the tube. Yeah, you read that correctly. I found a place to buy steel tube brushes. Justman Brush Company. I ordered the minimum of 6 brushes.

I’m going to run the brush through the tube until it stops the rust bits stop coming out. I’ve already poured “kitty litter”, you know the stuff that you use to soak up oil spills, down it until I was sure it wasn’t doing anything.

Once that job is done, I’ll reassemble. I’ve already bought all stainless steel hardware. I’ll protect the threads with copper anti-seize. This will hopefully limit the corrosion on the hardware.

That’s about it. If the brushes arrive by next weekend I’ll be finishing the tailgate and reassembling. If no, I’ll be working on the floor again. I forgot to disconnect the battery last weekend so this weekend I was reminded I have a slow drain somewhere in the wiring OR the alternator diodes have failed again. I’ll test next week by just disconnecting the alternator.
