Official Crawlbox BS thread!

Bit of a stretch here but anyone ever swap a multimode t case to a j-shift? Specifically on a 3rd gen 4Runner.
Sounds like the most feasible way to make dual cases work in a 3rd gen with multimode

 

Mines been drained twice in 7000 miles and it looked clean. Something is definitely not right. With that much material in suspension it should be painfully obvious what the issue is after you take it apart. Or just dump fresh fluid in it and check it in 500 miles. Eventually whatever it is will self-clearance.

I'm pretty sure Assburns swapped his to a j-shift. It's the same bolt pattern to the t-case. Ask him over at that other site. lol

 

Yea I'm pretty annoyed that I have to pull it all back apart, but I'm pretty curious on what it is that made all that liquid metal.
Hoping it's just the housing and not the adapters.

 

Frick, gotta go join that other site

edit: he’s got a 2000 so yes to multimode

 

I thought you already did. But yeah, join up. It's free. lol

 

Nope, I creep over there every once in a while but haven’t joined

 

How often do you all drain the fluid in the case?

 

x2 I think your on the right path with the reduction box housing being the reason for your aluminum milkshake. My first drain was similar to yours, had some metal but not that much. Almost looks like paste, any where did you slather up with antiseize too?

Before you fill with fresh fluid, get one of those telescope cameras with a built in light and look around, specifically the material around the countershaft gear.

 

Yea I put anti-seize on front input shaft and coupler as well as the rear case coupler and splines.

I did stick my boroscope inside the fill port, but wasn't able to see much other than some of the gear teeth. Couldn't really snake it around the corner.
Also didn't want to pull apart all my shifters & floor to look at it from the top.

Already filled it with fresh fluid. So I think I'm gonna run it for another couple hundred miles or so and check the fluid again. I can check it out with my boroscope from the top at that point if I feel like it.
If it's still all glittery then I'll pull it apart.

The inconsistencies between people's first oil change experience is just weird to me.

 

You've got a Kesha concert going on in your crawler!

^This, did you get the reduction housing really clean after you did the grinding on it and are you sure that you had enough clearance?

 

Didn't wipe it out, but I blew it out with compressed air. Sure that was prob some small bits left in there, but no way enough to make the fluid look like that alone.

I clearanced close to 1/4" between the 4.7 gear and the housing. Everything spun free just fine on the bench when assembled & doing dry fits.

Unless maybe there's some gear deflection under load that's causing it, but I doubt it.

 

What was the reason the bolts weren't lining up?

 

It was an adapter for a second gen

 

Don't have an answer for ya there. I would guess around the same interval as your factory T-case? Maybe different depending on usage?
Someone else prob has some better input

 

Per their IG post, they have more Dual adapter coming soon. I hope they mean for other model trucks, 3rd gen Taco specifically. Should I hold my breathe? Anyone hear anything through the grape vines ?

 

Definitely wouldn’t be holding my breath... they’re probably still filling orders from last year.

 

When Marlin uses the word "soon" it tends to actually mean never.

 

I know most people grind the bottom portion, but did you grind the top part?

 

I did not grind that part. Again, when everything was assembled, nothing was hitting and spun freely. Maybe I had a slightly newer casting or something?
Now I'm thinking that if it was hitting some part of the case, that would maybe be where...?

I just don't understand how it could be hitting some part of the case when I was able to spin it freely by hand on the bench with no resistance/contact inside.
