diff locks

[marlin]

seem to be just asking questions all the time but had a big debate with some of my m8ts today who all own pajeros seems I'm the odd one out
can some one please clarify dose the t2 1998/99 have diff locks fitted as one of my m8ts says that there is no diff locks fitted to the terrano and if i get 2 wheels in soft mud and 2 on solid ground it will just spin the 2 wheels in the mud and the 2 on solid ground will just sit there as there's no diff Locke's on them sick of taking stick of him
and as he as a pajero he will have to pull me out is this true
but ide still sooner have my terrano thanks

All T2s and Mavs are fiited with a plate type limited slip differential in the rear diff, there is no centre diff, so its like a locked one, the front diff has no locking action at all. Your mate is wrong the LSD in the rear locks up solid with it being a plate type. A gear type (detroit suretrac) or a viscous would not truely lock, a plate diff in good condition goes solid when it needs to.

There are no diff locks as the drive to the front and rear wheels is constant, the rear axle is fitted with a limited slip differential so the rear wheels can not spin independently of each other... I have not had any problems with my terrano on mud as yet, even pulling caravan on a muddy field up a steep hill, still pulled very well..

thanks for all your help and the quick replies :smile:

Done a quick google and early Paj's didn't have a rear locker at all and had selectable 4wd with no diff like that on the T2/Mav.

Later, post 91 Paj have selectable 4wd with a lockable centre diff, so they can be used in 4wd all the time unlike a T2/Mav but the diff can be locked when needed. Some of these are fitted with a rear vacumn operated locker with a switch on the centre console, some have a rear LSD like the T/Mav.

So if you're friend only has one diff lock selector on his Paj, he's basically got the same set up as us. That should shut him up for you.

It's surprising how many people think a centre diff gives some sort of performance advantage, when it simply means 4wd becomes locked and gives constant drive to front & rear; just like our vehicles in hi or low 4wd.

Lots of early discovery owners seem to think the centre diff is some sort of thunderbird rescue system, that they "can't get stuck, it has a centre diff".

Having got through lanes that have had LR's struggling due to the absence of axle diff locks, I can vouch that the rear LSD in our wagons is very effective.

Dont know if it is true but I watched a programe years ago that said if you cross axle or lose grip to one of the wheels you can gently press the break which stops the free running wheel and aplies presure to those with out.

I know that Range Rover use a similar method in their newer models where if a wheel loses grip the computer applies the brakes and lets the other wheels take power.

It works to a point, Eric Carleson was a great exponent of this when rallying Saabs and other FWD rally cars in the early 60's.

If used in conjunction with a gear type LSD, like a Detroit Suretrac or a Quaife ATB it definitely does work as these require some torque at both wheels in order to work, on sheet ice and a wheel in the air situation they revert to being open diffs.

I havent read the whole thread so may have been covered but!
dif lock on paj is to lock the central diff, all this dif does is avoid transmision wind up and allow changes from 2wd to 4wd at speeds up to 60 mph, it realy has no use off raod, when it is locked it behaves like the 4wd of a t2 with no central diff so your mate is wrong!

so it has no dif lock as it has no dif!

anyway all those paj's have the made in malasia cyclone diesel engine not made by mitsubishi and not very well built or reliable and they drink fuel, hows that fro a counter argument :wink:

 

[jace]

every electrical part on my engine and even the fan belt is made by mitsubishi!

Sorry Plank but perhaps you should have left it at that, swome newer Paj's have rear diff lock, read the thread.

 

[jace]

mates warrior has switch on dash for rear diff lock

yes but even without reading the whole thread the rear diff lock isnt part of the front wheels standing still if the rear wheels are in the mud as the thread began with surely?

 

[Terranosaurus]

He didn't say which 2 wheels, without a rear LSD or locker if one font and one rear wheel spins, either same side or opposite corners the 4x4 will stand still, old landies wee ven better, no centre locker either so just one wheel spinning could see them grind to a halt.

 

[marlin]

if one front and one rear wheel spins, either same side or opposite corners the 4x4 will stand still,

sorry guys should have made my self a bit more clearer in the post that's what i was meaning to get at if for instance the O/S/f/r wheels where in soft mud and the n/s/f/r/ where on good hard ground would it just sit there spinning the wheels that's got Les traction as hummingbird says but you guys have more than answered all my questions
and your right the paje do eat fuel recons hes on first name terms with the local filling station lol

I think the original post was referring to the situation when the wheels on one side of a vehicle are on a verge, and the others aren't. Any 4x4 with a part time or full time centre diff set up would likely pull itself out of the position you describe without blinking. As it is the situation of the wheels on one side of a vehicle loosing traction is of more concern, and potentially without a axle diff lock of some sort could see a vehicle stuck in an embarrasing situation.

and i think one of them is how fine the line can be between informative and pedantic :lol: :lol:
