Here's a short video going up the last hill climb on trail 16 at Windrock. I was aired down to about 15# for this first day out. I did drop to 12# on the second day but as I wrote above it was not a full day so can't say much other that I was able to drive over a V-notch with driver tires on the wall and passenger on other side on V at 12#. Again my camerawoman was not on duty so no video.
Oh my god that thing looks absolutely amazing. Keep the videos coming, this is like the only reason I check the forums anymore haha.

You should air down a lot more. I run 8psi on streetable 35" MTs in the rocks. Try 5 if you have a good quality gauge. Those tires probably won't even squat at all at 5.

Agreed. These tires can go down to 3. I had 12# on Sunday and next time out I'll try 8-9 and work my way down to 3. At this point not trying to do a lot of crazy stuff and just get used to width, suspension etc of this entirely new vehicle. The width and overall size is what's taking the longest.
So it's been quite some time since my last update and things will start flowing more frequently now. Was waiting for the Atlas to ship and just finished other jobs.
It was put back on the lift to get a good look at what really happened my first day out. A lot easier to look at everything when it's up in the air then on the ground and all dirty.
So here's what we found:
1. Both rear bump stops had issues. I knew this as I had to tighten them up after day 1. The passenger can ripped the frame a little. All is no problem and easy fixes. We will remove both and reinforce the frame in this area and fabricate different top to bracket to keep the cans secure.
2. The bump problem is what most likely caused my cut fuel line and hard starting issues but more on that soon. At some point the top of the rear links went up and first just barely cut the fuel line. The driver side top link went up and crushed the evap line, this alone is most likely what caused the hard starting issue.
3. Need to extend pad for front bumps a little as depending on angle of axle they are hitting the edge or sliding off under compression.
4. Few other minor details on links and steering rod ends.
5. For my major steering issue, we are going to add more line and either a secondary cooler, small fan, or something.
After 20+ long weeks the atlas should have finally shipped yesterday. Therefore we are hoping to get it installed in the next several weeks.
Things to complete after first run in addition to the items mentioned above.
1. cut rear fenders some more after the damage from the bump stops. This will create a little safety room. May rebuild rear inner fender wells.
2. cut little more and re-engineer the front fender wells for more clearance as there was quite a bit of rubbing under compression.
3. Thinking of moving the gas tank a little forward and rotating evap canister 90 degrees to make room for rear winch. I don't need this but I have a spare winch since I sold my LC200. You never know and I'm sure at some point it will come in handy.
I finally get my tow rig and trailer in a few weeks and we will go on a trip or two over the upcoming holidays. So the real fun and continued learning is close. Goal now as we approach the finish line is to always have the truck in a state that it can be put on the trailer and go wheeling.
I will also get some road wheels and tires to drive it some to fluids moving, batteries charged, etc.
Today we got the 4Runner weighed and if you look at my very first post in this thread you see when I drop it off, it weighed 6,000 lb and today with the spare tire in the back it weighs 6,680 lb. I would say if we remove the tire and put the drawers in it's going to weigh somewhere around 6,450 lb. All of the weight gain even after all of the cutting is coming from the wheels and tires. So really wheels and tires aside it has lost weight.
A question for you all. I was up at the shop yesterday as we were making a plan to get to completion as well as finish a few small things so we can get out over the holidays later this month.
In any case the atlas is ready to be installed and yesterday we discussed something which I never thought we would. Last year I was one of it not first to do yummy tuck to gain ground clearance in middle of vehicle.
Now we are thinking of clocking the atlas down , losing 2-3" of ground clearance in middle of the vehicle so we could have a one piece front drive shaft. The ground clearance would be no lower than the 4 link mounting points and it would be a flat bottom under the atlas.
At the moment I gave a 2 piece front drive shaft due to the packaging issues. There is a short shaft with a carrier bearing and then front shaft which goes down to front diff. If we clock the atlas down it will allow us to clear a lot of things, and maybe even fit two cats back in.
So my question, is do you agree with me that sacrificing a small amount of ground clearance ( I have 43" tires is this really an issue) in order to have a single piece front drive shaft worth it? I think absolutely.
agreed....with 43's its a non issue for ground clearance lol plus itll be more reliable. i bet those tires would eat carrier bearings.

I'd agree on loosing the carrier bearing unless it's helping to keep the drive shaft high and tight. The long rear shaft on a tundra for example needs a carrier for protection. I don't think the front shaft probably does on your 4R. Even with a low pinion diff.
Are you running a double cardan joint at the TC? I went back and looked at the mock up pics and it looks like a single u joint. It's always hard to tell from the pictures how bad the angles are. But lowering the TC outputs would help with those angles. Double cardan joints can also do a lot of good when you have high angle drivelines. The geometry gets a little more tricky if you do a single joint on one end and a double cardan on the other. That's how Toyota generally resolves those issues on its solid axle models. That was always an issue on front shafts in my past solid axle vehicles. My current FJ40 I built with double cardan joints on both shafts. I know high speed vibrations aren't likely on the list of things you're worried about. haha. But just an idea that might help with long service life by reducing the angle and binding forces on the u joints.
Figures, a worthy thread pops up after I sold my truck lol.
Should've planned for the Mickey 43! No, the 40s will work well. I run the 43 on another crawler I have. Those tires bite and are really soft for a DOT tire.
Originally we had the carrier bearing to keep it high and tight and keep it above the upper links. This kept the front shaft really short, which of course has limited the down travel. Do I really need 5"+ of more down travel in the front? Surely it will not hurt and make for some more fun.
At the moment I have single cardan drive shafts. In fact the rear shaft in there at the moment is the stock shaft that was lengthened and changed to 1410 u-joints. Once the atlas is put in we will have to get two new drive shafts not sure yet if we will go with single or double cardan yet. One step at a time for us at this point when we are so close to being 100% done. The angles when truck is on the ground is very good, but now looking at increased down travel will change things.
I have not tried the tires yet below 10# but yes they grip beyond belief and have potential to destroy a lot if not careful. We never intended on having these 43's or sticky mikey's so we are having go back and change things since we originally planned on 40"
Today we are taking out the springs and ordering new ones as what's in there is too soft. This is part of the reason for me having the issues with the bumps. This change today will come close to telling us if we go single or double cardan.
We need to fix the bump stop issues and that darn small rip in frame caused by it. We plated the frame a lot in the front and only a little in the back where we frenched the shock towers into the frame. that should all be done very soon and we will go back out for a second run with the truck. Probably back to Windrock or Harlan.
Sort list of things to do in no particular order:
1. fix 12 an line from steering res to pump, just need to make it a little longer to help with cooling.
2. Move gas tank forward a little forward and rotate charcoal canister to make room for rear winch, only because I own it and hate to see it sitting in cabinet.
3. close / dry in rear after the small amount of cutting we did...
4. exterior protection not sure what this means yet; armor, hybrid cage, combination. not sure yet.
5. trans cooler, maybe necessary maybe not. I think I will ere on the side of caution and have one put in. just need to find a place to put it. I'm thinking of using the howe heat exchanger or something like it in place a more traditional fan etc. I don't think we have a good place to put a fan....
6. at very end, abs sensors back in. Certainly not doing much if any highway driving but will do some small stuff around town (different set of wheels & tires). Can get speed from gps, but would be nice to not have all the lights on dash. Already have solution for steering light to be turned off from master tech at local toyota dealership. Also get the fuel gauge to work again. This is lots of little things which have no bearing on performance and just convenience.
It would be nice to be able to get two of the four cats put back in so I have a fighting chance to pass my emissions test. I have to get one in January but we have a "friend" to at least get it completed for '22.
If anyone what's specific photos of anything just let me know.
I hope to have more action videos up in new few weeks whenever we go out for next trip. Soon I hope to be able to be making much more. I have my tow vehicle and trailer now so not relying on others anymore.
