Limited slip diff

[extreme-4x4]

I must admit, I have thought about putting a sensor on the front prop shaft with a light on the dash that flashes when the front Auto-hubs are engaged.
(via prop shaft rotating).
Now with that flashing and the truck in 2wd you will know that you can engage 4wd at any speed.
Also lets you know if after reversing they have disconnected.
I just haven't had the time or inclination to do it in the 14 years I have owned my Mav.
Best regards,

what a sensor like the abs sensor..... so when was abs fitted to the t2. maybe thats why the stopped using auto hubs they needed the prps to rotate to get sensors on . just a thought:nenau

Nope, the MkII has ABS....at least on some models. Dornes has got it.

The ABS sensors look at the wheel hub, they don't care what the drive shaft is doing. If the hub are locked then the ABS sensor is looking at the hub/drive shaft rotation, if the hub is unlocked it's just looking at the hub/wheel rotation.
Hope that makes sense.!

some more expensive vehicles with factory satnav even use the ABS signals to maintain location and progress when satellite signals have been lost....cunning.

I have a Honda CR-V that does that,.. scary, going driving in an underground car park and the sat nav still claims it knows where its at.

Me again. All you guys with the AVM manual hubs, when they are locked on can you come out of 4W>High back into 2W drive without stopping and reversing a bit?

well i have very special hubs, there bloody welded lol, and i have been moving in and out on the move with no trouble at all, im sure the only time you need to stop is to engage low range!! the old series land rovers you can push the yellow knob down for high 4 wheel drive at any speed, but you must stop for low range, :thumb2:naughty

Yep I remember lifting my left foot and stabbing that yellow button into the floor...very satisfying, at any speed.

I remember the older Land Rovers, my parents had a 1966 swb. To disengage the 4x4 you had to stop and move the red knob back into low, thus releasing the yellow knob. Like loading an air rifle!
My Dad had this brilliant idea about saving petrol, and fitted the free wheel hubs. However the upper bush which was inside the hub (made of Tuffnol , cotton reinforced resin) relied on oil splashing onto the bush from the drive shaft, so soon dried out and became worn very quickly. Reading the instructions (later), as we all do, it said to engage the hubs ocassionally. Now we know why.:doh

Going back to the original question. Should theLSD slip then lock or just slip less than a normal diff? Whats the verdict on this one. Carn,t see it being that much help if it still slips. Tony

Nice one LACROUPADE that explaines it then. Not that much help for offroading then really as it says in the wite up. Thanks again.

Can't say I agree at all. As the article says it depends on the pre load. My last maverisks LSD was superb, in car parks and the like you could feel it lokking and the rear diff suffering from windup as the truck tried to grinf=d to a halt. Yhe one in my current T2 isn't as tight but I can still drive forward in 2wd with one rear wheel in the air. And I have driven in 2wd where similarly spec'd and tyred landies have and to use centre diff lock and low box which proves their use to me.

You have to remember that not everything on the net is true and things are often written from a perspective. No landy or Jeep guy is going to recommend an LSD as they have free diffs as std and go straight to air lockers from there. Also some landy owners fit Truetrac and other gear type LSDs to the front diff and they absolutely do not work with one wheel in the air or on ice etc. and thus all LSDs must be bad in some peoples eyes. the comment about no good on slipperly surfaces is plain preposterous, look at all those 2wd rally cars (and plenty production too) out there all with LSDs able to put big power down to 2 wheels on gravel, mud, ice etc. Anyone who has ever driven one will be able to tell you what a difference they make.

I haven't read the whole thread, but i find an LSD fantastic off roading, I don't know how anyone with experience of one could think otherwise!

I have found a SWB t2 with good tyres can conquer most things in 2wd due to its limited slip diff

in fact if you look at Milner off road racing, the trucks they set up for their own racing endeavours usualy use 4wd with an open front diff and LSD rear, why if they are of no use?

I used to break a few Troopers and the first questions i would get assked was, 'has it got a LSD if so how much for the back axel and allways from off roaders!

I guess you're right, but its better than nowt and more manageable than a locked diff can be....but seriously, give the old girl a go offroad first, I promise you'll be genuinely surprised at what even a standard truck is capable of.

Have you ever been up Strata Florida? Where in SWales are you?

 

[Thomas-the-Terrano2]

hey i love my troll, but wish it had the lsd from my t2, a locker like the
troll has is good but its all or nothing. used it today instead of 4wd but
care is needed not to engage it if one wheel is spinning more than other
so have virtually stopped car first loosing what traction i had. that said
so got it moving again locked and easily switched off but just not as
easy as the auto lsd.

LACROUPADE, I live in RISCA which is just outside Newport. To be fair I have only been on the mountain local to me which was deep in snow. It perform well enough on the tyres fitted. Bit disappointed with the LSD, I thought it would spin then lock. Used to have a 90 landy many moons ago and had a Detroit locker fitted to the rear diff. Absolutly brilliant imo. You could drive along a track with 2/3 foot sides and turn into them and drive up over them. Tried it yesterday in my Terrano and as soon as my one rear wheel left the ground it just spun away, still relativly easey to cross axle it. I have found many different 4x4s realy impressive most of the time offroad, then other times you carn,t believe how easey they get stuck. I do like the Terrano though. Havent done the S/f. Tony

Must be something wrong with the LSD me thinks
Mines brill at almost any angle:lol

See where you're coming from now with the LSD then.

I'm up at Llandovery (weekends anyway, Extreme is near Banwen/Seven Sisters, Makeitfit is nar Cardigan on the beach an Adz comes a-visiting from time to time. I haven't been out much due to building works but you ought to come out for a run one day. SF is a fantastic route.....

Lacroupade where do you live then? Only bought the truck for the winter really. Dont mind having a play on any non damaging stuff. Dont want to fill it with muddy water or knocklumps off it. Did that to my last 4x4 (SWB landcruiser, no LSD but good offroad)
