2) Douglas - couldn't be happier to pass the torch. As we talked about yesterday, other than me having to say goodbye to a ridiculously fun rig, I couldn't be happier that she's going to a perfect home/situation. The stars aligned in a pretty crazy way I think. Looking forward to watching the progress as you perfect her, and getting on the trail together soon.

I'll be the one in the work-in-progress soccer mom mobile:kevin:...just look down from your new drivers seat and you should see me.

This will be me looking down on you:

She will suddenly be coming along a lot faster now...now that I slaughtered a white lamb mini-truck for the Land Cruiser Gods...

Congrats Douglass, that's one way to turn a 4 runner into another 4runner.

Something I've noticed while playing around with the truck is that the front T-Case pops out of low range when I put it in high range in the rear T-case (it has dual shifters in the rear, doesn't matter if it's 2WD or 4WD).

I'm thinking that this post on Pirate 4x4 might be my problem:

http://www.pirate4x4.com/forum/toyo...a-dual-case-shifting-problem.html#post6989252

Is there an easy way to tell if that's true before I decide to drop the T-cases out to fix this? It doesn't really impact much other than that I don't have access to a few ratios.

You might be able to pull both shifters and shift the rear case with a screwdriver and see what's happening, since you'll be pulling the rear shifter, anyway.

Did the PO have the problem, and do they remember cutting the rail?

I can't remember if you said what ratios are in the cases, but you'll want to fix it if you have 4.70 gears in the back. Having stock low range is really handy on easier trail sections.

Townsend is the PO but it was the PO before him who did the dual t-cases. Both he and I noticed it when we took the truck for a spin a couple weekends ago.

4.70 gears are in the front case.

I'll see about taking a video of the behavior later today once I get some breakfast :D

As luck would have it, I do need to take the rear t-case twin sticks out to install an oil slinger plate when it arrives from Marlin Crawler later this week...

So you have 4.70 in the front, and 2.28 in the rear?

Mark

Yup, I believe so. The sticks are labeled as such and it appears that's the way the gears are configured when I engage the T-cases. Because I'm way too curious, I really want to open it up and see for myself but I'll save that for some distant weekend in the future when I need to rebuild one or both of the T-cases :D

I just took a video. It's still processing but it will be available here: https://www.youtube.com/watch?v=a-Q12Rl_I4E

It's like both sticks are linked together. When I try to put the front case into low (4.70:1) and the rear into high (1:1), either one or the other t-case pops into neutral.

Couldn't see the link but I'm betting they didn't cut down the shift rail enough when they did the dual conversion. The low range rails occupy the same space when the rear is in high range and the front is in low range.

Don't ask me how I know :D

It's a pain to fix. Sorry man.

the 4.7 case needs to be the rear case.

Good thing I have spare seals kicking around to reseal the cases when I have to drop them and crack them open to swap around the gears... What a pain!

What is a good strategy to get both t-cases out of the truck at once? I know I can't bench press these to the ground on my own. Do I need an ATV or transmission lift or something similar? Is this a one afternoon or multiple day sort of job?

I rented a transmission jack when I installed my dual cases years ago. You could probably use a good sized floor jack, too.

Also, while I prefer the 4.7 gears in the back - mostly so the torque gets multiplied as late as possible - I don't know that they *have* to be. With twin sticks, you'll still have the option of stock 2wd low range, which is handy.

Marlin seems to recommend putting the 4.7 gears in the rear case: https://www.marlincrawler.com/tech/guide/4701-gear-install

Might as well do it to help ensure the t-case gears don't have trouble down the road. Only issue might be if there are a mix of 21 and 23 splines inside. That would change what gaskets I need to use to re-seal everything. Hmm... might be better for me to pay a shop to sort this out for me. I can't have it in my garage longer than few hours at a time this time of year due to :Princess:'s car needing to be inside when hail threatens.

I also suppose I should verify for sure that the gears are in fact configured the way I think they are. They're labeled with the 4.70 gear in the front and it seems that the 4.70 gear is in the front but I haven't verified for sure.

That's easy to figure out, as you'll recognize a different feel on clutch takeup, and speed at a given RPM.

If they are installed with the 4.7 gears in the back, you shouldn't have to remove both cases to cut the shift rail on the rear case.

I'll see about taking a video later today driving it to try and determine what the gearing is. It's definitely slower when I engage both cases.

Marlin recommends factory gearing in the middle box because the torque is multiplied and you don't want to grenade a 21-spline input gear. If you run a 23-spline in the back case then the middle can be 4.70, too, although having a factory ratio somewhere is still handy. I only ever ran a single 4.70 case and really missed 2.28. So much so that I actually removed the 4.70 case and put back in a stock one since it worked better for what I did with the truck. The 4.70 ratio is only really useful for technical crawling, otherwise I would always be in 4th gear trying to keep up with other people on more tame trails. In reality dual 2.28 cases are all I'd have ever needed for ratios and using 23-spline 2.28 gears would have been my choice. Both engaged get plenty low and there's a lower risk of destroying your drivetrain.
