Post Hilux 3.0 D4D D/C 4x2 to 4x4 conversion.
Good day,
I recently bought a diff,propshaft,gearbox & front diff from a 4x4 Hilux D4D D/C (2008 model).

Everything went smooth with the conversion from 4x2 to 4x4.The only hic-up be the center bearing brackets that needed to be moved backward.

The only problem i did encounter and not know how to solve be the "electrical plug" on the front diff to engage the front CV shafts and the two plugs on the gearbox, telling the "system" that the vehicle is now in 4x4 mode. (There is no "extra" plugs to do this)

Any help & suggestions will be appreciated.

There is a seperate control unit to manage the switching of all of this because there are limit switches in the diff to stop the motor once its engaged and vise versa. It would not be difficult to wire something up using relays

Thanx for your replies, maybe, just maybe some one already did solve this problem, lets hope that some will give us the answer.

Another question, why do Fortuners only come in permanent 4x4.

The 4x4 Fortuners are permanent 4WD, even the 2nd gear lever only shows 4H for normal driving

Surely Toyota would have thought that driving in 2H (RWD) would return better fuel consumption? (Like the Hilux can)

Good day to you all.

The Fortuner comes equipped with Full time 4x4, Torsen (torque sensing) limited slip differential and a dual ratio (high / low) transfer case. The diff is lockable too.

4x4 Drive Options:

Broadly, there are four options on the transfer box (smaller gear lever).

H : Default mode. Running in all time 4x4 with the center diff unlocked. This is what you will use 99% of the time. For tarmac use.

HL : 4x4 with center diff locked. 50:50 torque between the front & rear axles. Do NOT use this mode on tarmac (you will ruin the drivetrain). Best in slush, sand etc.

LL : 4x4, center diff locked, low ratio. Use in extreme offroad applications. Only crawling speeds possible.

N : Neutral. No drive provided to the front or rear wheels. Purpose is to serve as a bridge between High & Low ratio shifts.

All my 4x2 to 4x4 conversion problems is solved :mrgreen:

Thanx for all your replies.

Hi Titos
I am new to the forum and its your artical that, made me join. I have a 4.0 v6 auto d/c hilux and wondered if i can also do the 4x2 to 4x4 conversion, do you think i could get away with all the stuff that you used for the conversion, reason for asking is the local 4x4 place here said i need the full front suspension aswell, is this true. Second question is what did your converion cost you and what did you do with old gear box.

Most trails require 4WD. You could however attempt some easier trails but would most likely do some damage to your vehicle and environment as you would have to have more momentum going through obsticles. Al lot of trail owners would however not allow 2WD vehicles.

Agree ..... not adviseable to attempt a trail with a 4x2 that's intended for a 4x4 vehicle.

IMO it's a better all round option to sell the 4x2 and put the proceeds towards a good 2nd hand 4x4. The difference that you will pay in is going to be less than what it would cost to do the conversion unless you can source good 2nd hand parts and do all the labour yourself, and then you're still looking at a fair period of down time. Whereas, if you sell and replace, there is no down time and it's a factory fitment and no niggly issues afterwards.

Good day Shadow 14 & NBL 513, yes it is possible to convert both your vehicles to 4x4. Unless you both did spend a lot of money on your vehicles eg. bull bar,wider wheels, canopy etc, i would rather sell my vehicle and buy a 4x4 like Oooms suggested.

Hi Titos. Did you have any joy with the conversion. What were the difficulties?

For the record, the conversion is possible. The biggest challenge was finding someone to build the harness linking the front diff and transfer box to the computer and instrument cluster. Minor challenges included lengthening the speedo wires, building a new prop-shaft carrier mounting bracket, accommodating the ABS, and the gear-lever opening in the cab floor. The front diff, side shafts & hubs, gearbox & shafts all fitted without problem. The donor vehicle was my 2.5 SRX single cab, which is now a working 2x4. The components donated were the gearbox, front and rear diffs and drive shafts, side shafts and front hubs, computer box & harness plugs.
