I agree, that's one reason I don't have any sub's to any off road magazines anymore! Those are some sweet looking yota's in there! I think Volcom had his 4 runner in Crawl magazine before, if I remember correctly...that would be pretty cool!

As winter is slowly approaching, I have been thinking of some things to get done in a hurry. One of those was to do a test run on the outside of the frame rails in the rear fender well.
I eventually want to do the entire frame, well everything I can get without taking the body off.
I used a flap wheel disc on the frame I get all the existing undercoating and crap off. Made it nice and smooth. Then I decided to slap on some POR-15.



Sorry for the blurry pics.
Put two coats on. From my own experience, you must put at least 2 coats on or it will still rust.
After that, I decided to put some black primer over and then top coat with flat black paint. I probably should have used gloss so dirt and mud would less likely stick to it. But I'm not a huge gloss black kind of guy.
Final product

While I was poking around, I decided to stick my bore scope down into the frame to see the condition of it. I was afraid I would find some rot.


Much to my surprise, there was no rot in the typical area near the front of the rear leaf springs. Just typical surface rust.
I really think that I am going to try and test the waters with used motor oil in the entire frame. I am going to try and get one of those nozzle ends that spins and rotates 360 degrees. Get it in as far as I can.
I think the best way to get a nice rust free frame would be to SAS a clean 2wd truck like the one in the build for a buddy thread. It is so clean on the inside, it's scary. I feel like that would be the only way to really have a rust free frame that you could then spray some inner frame sealer.
Other than that, I need to do the rest of the frame, put on my homemade sliders, and rebuild my front axle. I would really like to do this before we are too deep into winter.

Nice work on the frame, it turned out great! Glad to hear that you don't have any frame rot!!!
I always wanted to sas a 2wd, it would be cool to do a early 70's Toyota 2wd, or a Toyota Stout like the one on the pre-84 buildup section.
When did you build the sliders? Got any pics?

I love those older Toyotas
I built the sliders a year or so ago. I haven't touched them since. They need finished. I cannot remember where they are at in my build thread, but I put some pics up when I was working on them. I'll snap some pics on Monday.

I just finished going back through your build thread, man you've done a lot of work, over a short period of time! I forgot that your runner had an exo cage when you first got it. Found a pic of your sliders on pg #3 they look really good! Can't wait to see them finished and mounted!

Frame turned out great. Glad to hear there was not any frame rot. I never heard of frame issues until I got into Toyotas. Second one I bought is how and why I had to get into doing frame swaps. Winter will be here to soon and need to get my frame coated. Using the bore scope was a great idea.

lookin good! i ran into some rust when moving my spring hangers, ended up cutting a chunk out of the inside wall of the frame and welding in a 3/16 patch. i didn't realize that was such a common problem on these trucks... kinda scared now of what the rest of my frame looks like inside

I have had my fair share of frame repairs on these trucks. I always get a little Leary when getting a new one because you never really know what the inside of the frame look like.
I might start bringing my borescope and probe the frames from now on. There have been a lot of trucks that were beautiful that I almost bought but the frames were junk. And the dudes selling still wanted top dollar for them.
You know the typical Toyota seller that doesn't know anything. Frames hanging off on the ground, and they are like "but it will run forever"

I have thought of closing up all of the holes on the frame but wonder if that would still trap dirt in the frame and just make it worse. Maybe adding a few holes on the bottom for moisture to get out. What are your thoughts on that? I do spend a lot of time making sure my frames are cleaned out but not sure how things are going to be on the long run as I have only been doing a few years now.

I think the only way to make sure it doesn't rust is to get it as clean as you can if not brand new, and use something like the Eastwood industries inner frame sealer. It's a multiple stage stuff. And then do period I cleaning out of the rails. Sounds like a lot of work, but I think one could keep the frame nice and in good shape for a long time.
Problem for me is that the days turn into months before I find the time to make sure I check that stuff. Then before I know it, I have rust or rot.
