0xC209B

Hey guys I'm new here and I've got a question.

English is not my first language (from Russia with love ) so it may sound a little bit awkward.

A little background: 2009 face lifted(2012) LX570 with TRD supercharger and big brakes kit

So, question is:
How can I turn off front-wheel drive (primarily for some burnout and for fuel economy) ? Any ideas?
As far as I know LX has full-time 4WD with torque distribution 40% FWD and 60% RWD.

I've found front axle from tundra 5.7 and it has an actuator which turns on and off FWD (pic https://i.ebayimg.com/images/g/~iIAA...hj/s-l1600.jpg ).
But I don't know how torque will be distributed when FWD is disabled and first of all will it axle fit to LX?

Not with LX. Don't think there is a way to disengage the front axle.

Maybe you could find some front manual locking wheel hubs for LC 200. But I am not sure if they exist.

...other than removing the front driveshaft.

Old 4x4 tricks to get home after pushing the rig too far...remove the shaft as @hankinid says. Now, I'd study the transfer case first and ensure the rear can accept 100% of the power and that there won't be other repercussions. However, on our old Land Rovers we removed front and/or rear drive shafts to limp back to camp many times! However, we weren't doing burnouts either.

Manual hub options for the front may also be applicable if you can match up splines and other criteria.

But again, between all of the nannies like traction control, complexities of the transfer case and power distribution, and so forth...not sure if the marginal fuel economy gain + the occasional burnout would be worth the effort (and potential financial risk if things go wrong).

Hi guys, finally, I've done it.

How did you do it? What is the change to gas mileage for normal daily driving?

0xC209B

Totally replaced transfer case and final-drive-gear(rear and front) from Sequoia.
+ 2 line locks to disable rear brakes.

about gas mileage.... actually i don't care cause fuel consumption is about 8 mpg and over. But I think changes are minor.
