Prado electric difflock, how to engage when only in 2wd?

IcedJohnno · Post by **IcedJohnno** » Thu May 03, 2007 2:38 pm

I need to engage my difflock this weekend in rear wheel drive only. This is to drive the small rope tow mention in the flyer on the home page.

The back axle of the vehicle is on axle stands and one wheel is driving the rope, therefore I have to engage my difflock to maintain drive or double the wheel speed by putting all the drive thru one axle via the differential. I don't want to do this.

There is a lockout in the system so that the difflock can't be engaged until 4wd is selected. So I could leave the vehicle in 4wd and just not engage the front hubs. But as I still have factory electric front hubs I am concerned that somebody may put their hand on the dash and accidentally hit the button and engage the front wheels resulting in a front wheel drive Prado that will drive off!! The other option is to remove the front driveshaft but if I can avoid this work I want to!

I know the 4wd only activated difflock can be bypassed but don't know how to do this. Can anyone help please?

Or can I just disconnect the front hub button and maintain the illusion of 4wd?

I prefer the 1st option if anyone knows how
Thanks in advance
John

I dunno anything about how all the electric's do and don't work on those things but being a public sort of even whatever you will have to be fool proof to ensure the event's safety even if it means dropping the front drive shaft out for the day.

Yes I agree, it has to be completely foolproof

I would have a look at the 4wd relay in the passenger kick panel, I would have though it would be linked into that somehow.

8 bolts - I hate electrics, by the time i would have tinkered around looking i would have had the front shaft out :wink:

but then i have a LR which has three wires, one to the coil, one to the earth and a push button for the starter solenoid and I think thats a birds next :roll:

Taking the drive shaft out at least you can be assured there is no chance of it driving off :wink:

you only need to remove the transfer case end of the drive shaft though

true

just tie it up. so its only 4 bolts now

Just dont engage those hubs while your driving along :wink:

you know what damage an unsupported piece of stock out the back of a lathe can do

Yeah thatâ€™s the simplest answer for electrically challenged types.
Where there's smoke there is wires, I say

I had figured on the rear of the shaft only, and yes Mike I'm sure we have both had exhilarating moments with material too long and too thin out the back of the Lathe spindle :shock:

However I know that someone knows about this quick electrical bypass.
I have heard about it before.

Anyone else know?
