Oooh that looks freaky. Hope you can sort it out before it becomes a catastrophe.
It would be interesting to see what grade bolts are used in there and if upgrades are possible.

Anyone else see this type of failure?
This could get exciting very quickly....see video in link.

Wow.. That sucks man, definitely curious to see what you get when you drop the tcase…

Dual cases dropped and torn down. Turns out the clockable rear adapter was shipped with 30mm bolts and they were bottoming out and not actually getting tight. A quick internet search showed Inchworm originally shipped with 25mm bolts. I talked to Marlin Crawler and they said they test fit 30mm bolts in a set of adapters and had plenty of clearance. Maybe I got an old set or the holes were not drilled deep enough. I really don’t know. Maybe I am completely wrong…
Problem solved…ordered 25mm bolts. Marlin did ship a new install kit but it included 30mm bolts so not helpful. They did send all the missing set screws I needed to block the unused bolt holes for clocking. This is nice because last time I had to fill all the hoes with RTV… I also replaced my transmission output shaft seal as the old one was shot and I ran the tranny pretty dry (more on that in a min). No idea if the seal failure has anything to do with the loose clockable adapter issue but I can imagine any extra torque at that seal might be a problem but I really dunno.
Everything is now reassembled and installed and after 30 mi or so everything seems ok with the exception of my tranny singing a little in 1st, 2nd and 5th. It shifts fine and stays in gear fine. I am not sure if anyone else would notice the sound except for me but it is definitely there. I am running Redline MT-90 and will change it out a couple times in the coming month and hope it helps but I am pretty sure I cooked some stuff.
Anyone have a lead on a rebuild kit for a r150f? Or a used transmission in good shape? Would be nice to rebuild a spare while running this one.
Overall this has been an experience…I am a little frustrated with MC but anyone that gets into modifications like this does so at their own risk and I beat this thing up when I can so I suppose this comes with the territory. Glad I can do most of this work myself but think a new daily driver is on the horizon…maybe a new Tundra….we will see. Would love to do more stuff to this thing but feel limited right now.

350 mi road trip this past weekend…no leaks, everything remains tight. Received an apology package from Marlin Crawler. Nice gesture on their part! I have some other maitenance coming up this week…hopefully no surprises.

Spark plug time…really should have been done awhile ago…last done Oct 2017 and the plugs on the drivers side looked pretty worn. Denso IK22 plugs, wires and decided to see if new coil packs would make a difference. I have read these rarely go bad so I will see what happens and save my old ones for backup. Also…a buddy is an Amsoil dealer and let me order at his cost so we will see how magical their stuff really is…doing engine, diffs, transmission a dual cases. Probably next week…

Rear Power Panel
Not super exciting but I wanted to be able to measure voltage when using the rear aux plug while camping to make sure I don’t drain the battery. Found this nice 3D printed rear power panel that came pre-wired…too easy to say now. I simply wife’s to the existing factory wiring…not expecting any high current draw here. Too easy!

My buddy is an Amsoil dealer and let purchase at his cost! I changed out all the fluids in my engine, transmission, crawlbox, transfer case and f/r differentials as well as oil/air filters. I am curious if I see a difference dropping from Lucas 85W140 to Amsoil Severe Gear 75W90. We shall see. 4Runner is mostly ready for camping season to start here in Florida in the next month or so.

Did you get the Amsoil MTG for the manual transmission?

I called Amsoil before placing the order and they said running the Severe Gear 75W90 (GL5) instead of the MT 75W90 (GL4) should be fine in this transmission. I have heard the GL4 vs GL5 debate but I figure the people at Amsoil are smarter about this than me. What are your thoughts?

GL4 for the win! Shifts way better. The Amsoil product is great and so is redline MT90.
GL5 won’t hurt it but it will make it shift worse. Only hypoid gears need GL5. Helical gears in trans and tcase can use it or GL4 happily.

I have been running Redline MT90 for years and been happy. With my recent crawl box woes my rear transmission seal failed and I ran the tranny dry and am sure I roasted some bearings…I have done two short interval fluid changes (with Redline) in hopes of cleaning things up and hoping I might salvage some impending disaster. (I have a bearing noise on cold starts that goes away when you step on the clutch and comes back when you take your foot off. After driving around for a bit it goes away). Maybe I will run this GL5 for a month or so then switch to the Amsoil GL4 and see if anything changes. I actually thought things shifted nicer after replacing with GL5 but perhaps that’s because the other stuff was dirty, though it was still somewhat clear. Time will tell…Hopefully my bearing noise goes away!!! If I need to rebuild my tranny I need to start looking for a shop. I know Marlin has a good reputation but their turn around is terrible…I would have to source a spare transmission to send them just to make this make sense…hoping I can find something local if I need to go this route.

Might need to try this with my rig? Great idea especially when spending days out in the woods!

Lots of questions…Would you mind telling me what all was replaced and ballpark cost? Did you notice much of a difference after putting it back in? What led you to having it rebuilt?
