Sooo, my frame and drivetrain are all pretty much entirely covered with a layer of surface rust and scale. I'd thought it was pretty superficial, but I didn't want to to get any worse. I considered laboring away under the truck to paint the exposed parts of the frame by hand, but I knew that wouldn't really fix the problem... There would definitely be places I couldn't get to and it would be a total PITA. Mostly, I just want to be totally sure that any rust or issues under the truck have been dealt with so I can drive in the rain/winter/etc and never have to worry.
That of course means I gotta take the body off. I thought about this for a year and had planned to spend the fall and winter restoring the bottom half of the truck. The goal is to:
Take the body off
Strip down the frame
Strip down the axles and all the drive train
Clean everything up and replate all the hardware
Powder coat everything else
Rebuild transfer case
Add an H55F and probably 4.10 gears
Balance drive shafts
Replace all bearings, etc
Put everything back together
I also want to deal with the underside of the body.. IE get it painted or undercoated.
This way, hopefully by spring, the bottom side of the truck will be restored and totally good to go. Any future work won't require taking the body off. Then, possibly next year I'll take out the interior, glass, etc and get it painted a different color. Possibly then I'll also get the engine rebuilt and a Holley sniper added.
The main issue with taking the body off is that I'm relegated to my half of a two car garage plus an additional single car concrete parking space outside. Not much space and I definitely don't have a lift. I spent a lot of time figuring out the best and safest way to get the body off with my tools and space. I settled on using an engine hoist connected to the seatbelt mounting bolt holes.
Overall, this worked pretty well. It's definitely a two person job, and you also have to remove all the front body panels. I found that the body leaned around a lot while lifting so the second person is there to hold it level. We jacked it up enough to get two 2x6s under the front and rear pinch welds supported by 4 cinder blocks.
This was just high enough for the transmission and tires to clear the 2x6 supports. I was originally concerned about stability so was going to re-lift the body and lower it , but after getting it up there it's solid... No amount of pushing or rocking gets it to move at all.
Overall, it took a few days to get all the parts stripped down, everything setup, and the body off. But overall it went pretty smoothly.. The process definitely included tons of stress about "am I actually doing this" and "what kind of hole am I digging for myself". Hopefully this won't be a terrible idea.
Here are some pics of what it looked like right after pulling it out:
