Pajero Owners Club of South Africa

Hello everyone!!!

Ok...now I understand my pajero has an autolock systems for the hubs, so I wanted to use it just to see the differencie but I don't know how to engage them, I read on the pilot door a sticker that says that we can lock them by only selecting the 4h and moveing the pajero in reverse for about 2mts. I did so but nothing happens, I mean, is there and light that can tell you the lock is activated? if so, it never turns on, it maybe that the lock is damaged? how to check it?

BTW...I have a GEN 1

I am glad I found this forum, we talk same pajero language jejejeje

Regards to all from Mexico

Hi Gomi

If you have a Gen 1 I doubt that there is a diff lock fitted. Unless off course the diff was changed with one in or an aftermarket diff lock was installed. The Auto locking of the hubs (front) means you can engage 4x4 without getting out of the vehicle and manually turning the hubs to 4x4. Putting it in 4H means that you have engaged 4 wheel drive. There should be a light in the console indicating that 4wd has been engaged. You can refer to the troubleshooting 4x4 light thread above in this section to investigate that. You can generally "feel" the difference when turning that 4x4 is engaged. oherwise you will have to go on gravel road or go up against some inclines to make sure that the front wheels are also "gripping" and pulling.

Just be carefull here. The Gen1, and all other Generations of Pajero, all have a CENTER difflock as standard. The difflock that you are revering to is of course an axcle differential difflock, which was not standard equipment on all Pajeros.

Gents,
I think the title of this thread could be misleading us.

Gomi wants to know about the locking of his hubs. I'm not aware of a dash light to indicate that the hubs have locked. The best test is to try it out on a slippery surface, without getting stuck should they not be engaged.

Good luck

Gents,
I can only agree with Roelf.
In addition, to CATS:
The Gen1 doesn't have a CENTER difflock as standard. Gen 1 doesn't have even center differential.
This standard was started for Gen 2 with SS4 system (Super Select 4WD). System Easy Select remains without center differential at all.

I think Jenki is right and wrong - Yes, there is no selection of CDL, but No, once 4WD is selected, the front & rear is locked in.

My understanding is that Hyundai followed this route as well. There is a lot of overlap between Galloper and Pajero Gen 1 and the Terracan and Pajero Gen 2, but the SS4 is unique to Pajero - from Gen 2.

Many owners of 4WD vehicled confuses hub-lock with difflock.

With hubs locked, but no difflock, my understanding is that in a cross-axle, all power can be lost through one wheel, with CDL engaged, all power can be lost through 2 wheels (LSD helps a bit here), and with RDL engaged, there will always be power in at least both rear wheels, while FWD traction could still be lost through one front wheel when a front wheel lifts. With RDL plus FDL, you have a tank!

Anton

LSD = Limited-Slip Diff (Rear)
CDL = Centre Difflock
RDL = Rear Difflock
FDL = Front Difflock

Be honest, I really don't know where I'm wrong.
There is no center differential (it means, you don't need to lock it and you can't unlock it) on the Pajero Gen 1. (system is the same like Patrol GR, for example).
If you have 4H engaged on the Pajero Gen 1, system is working the same way as 4HLc on the Pajero Gen 2. The power is distributed to front and rear axle and power can't be lost through one wheel (only through one front and one rear wheel together).
Lock the differential always means that differential is not working more (is locked).

Front wheel free or manual hubs are different story.

Both saying the same thing, and both correct IMHO.
There is no differential drive in the Gen1 transfer case. The front and rear output shafts are always engaged (when in 4WD).

Auto-lock hubs: These beauties engage automatically (by mechanical means) the moment the front diff is engaged. The rotation of the drive shafts causes the engagement.
There is no tell-tale light or similar.
You have disengage the front diff and reverse a few meters for the hubs to un-lock.
They were discontinued in the Gen2 (because one drive shaft always rotates, I think)

This sums it up nicely

Gen1 = Easy Select
Gen2/3/4 = Super Select


certain gen2 models and certain gen3 models came with rear difflock from the factory. Gen1's with rear diff lock are retrofitted. Later Gen3's and Gen4's didn't have rear diff lock as mitsu gave them Traction control.

Gen1
2h - rear wheel drive - front sideshafts stationary - front diff stationary
4h - centre diff locked - front and rear propshafts turn the same speed - same as gen2 4hlc but have to reverse to go back to 2h
4hl - same as 4h but low range

gen2

2h - rear wheel drive - front left and front propshaft connected - front propshaft not connected to tranny
4h - all wheel drive - front and rear propshafts connected via VCU - similar to viscous clutch or torque converter
4hlc - front and rear propshafts turn at the same speed - vacuum actuators engage front right sideshaft to front diff via electric solenoids based on sensors on transfer case and front diff
4llc - same as 4hlc but low range


centre diff open
gen1 - 2h
gen2/3/4 - 2h

CDL
gen1 - 4h
gen2/3/4 - 4hlc/4llc

AWD/VCU
gen2/3/4 - 4h
