Twin sticks

[Mark m.]

Is there any advantage or disavantage to using a twin stick in the rear case of a dual case setup.

Check the description on the catalog page.  http://www.marlincrawler.com/twinshifter.html
With the twin stick you can control High/Nuetral/Low with one stick and 2WD/4WD with the other. Thus you can acheive 2WD Low with your front hubs locked and you also get a true nuetral for flat towing. Does that help? I don't know of any disadvantages. As far as running it on a dual case setup compared to a single case you can use your extra low range option but that is not given to you by the twin stick. Hope that helped

Great answer, 90TOYPU.
In the near future, you will be also be able to shift into front wheel drive only.

So with the twin stick I can flat tow without taking my driveline off. I'm also running dual cases. If so what position should the shifters be in. Thanx for the help!

Toyota advises to shift the trans in 4th gear and shift the rear t-case into netural. This stops the trans from spinning dry and cirulates the oil in the t-case so the bearings, gears, and shafts will not fail, but the front driveshaft now spins all the time. This is not good. I have seen many front driveshafts come apart at high  speeds.
Towing the Marlin dual case in netural, and the rear case in 2 high will circulate the oil in the rear case, but the cage bearing on the front input gear will starve for oil.
Towing in; trans-netural, Marlin-high, and rear case-2 high, will starve the trans main shaft cage rollers for oil.This can be done for short trips-less than 5 miles?
To play it safe, remove the rear driveline (best), or get a rear axle unlocking hub kit from Brian at Front Range Off Road (good but cost $$$$ and adds weak links), or leave the engine running in netural, Marlin in high, and the rear case in 2WD (would work but risky).
After all this explaining, I have a customer that towed his 4x4 truck behind his motorhome in netural, and the Marlin in high, and the rear case in 2 high for many, many miles with no problems

Thank You for the info.

What do you consider to be the "weak links"?

To install the rear wheel disconnect, Front Range Off Road is using the complete spindle, bearing hub and rotor, locking hub assembly from a 79-85' 4x4 p/up.
From the factory, the axle is one piece. By adding locking hubs, You now have added backlash between the end of the custom axle and hub sleeve, sleeve and hub body, and all the torque now must go thur the 6- 8x1.25 studs and 2 factory 5mm sheer pins. This would be a great concern if I had it installed on my truck
I would advise presicion drilling the hub body and installing 4 more sheer pins. Then offer a alloy sleeve
To my knowledge, Brian does not offer an upgrade!
For light duty, the factory set up would work ok, just check the hubs to make sure there tight, and go easy on the clutch.

Hubs in the back = :atombomb:

Thanks for the anwers on the Full Float Kit. Would you agree that running drive flanges and adding extra dowel pins would solve the weak link? Thanks again for your help.

That is  a lovely pic CRUZILA

On the FJ80 flanges thet are shaped so adding the extra dowels is not possible. BJonroids posted on PBB about upping those studs to 10mm. Cool idea  8) 8) I need to search and find the p/n for the studs and cones. Then there is the tapers needing to be opened up.

So if i install twin sticks on my 04 Tacoma 5speed 4wd can I flat tow it?

[firemanjohn]

Yes you can do it with the twinstick , but to play it safe like Marlin stated remove your rear driveshaft.

[TonkaTaco]

Thats funny, I just talked to Dean at Crawler and he talked to his "best" toyota tech and the tech says I can tow it simply by putting Tranny in N and tcase in 2H. Wow that is toataly different from what everyone else is saying. Does he know something that others don't.

those rear hubs can also make for some fun practacal jokes, muahaha
