Discoveries and the smaller Land Cruisers don't have rear diff locks, not sure about the large (Amazon) LCs though.

Amazons are either the last 80 series, up to about 1997 'ish or newer 100 series.
(There is the new 200 series now, but not sure this is called 'Amazon')

My Land Cruiser pictured above is the 120 series, which followed on from the 90 series Colrado.

I can assure you the 120 series, as pictured above, up to about 2007, all had mechanical rear diff locks, and mechanical center diff locking. Normal center diff, unlocked mode was limited slip type,
After that they had the electronic 'wheel braking' to prevent the 'non traction ' wheel from spinning in free air.

Sorry my mistake, I thought the Toyota had a centre diff lock the same as a Disco, mine is indeed a rear diff lock.

Axle diff locks are very useful, but often aren’t needed. Can cause more trouble than they are worth when used, often break things and only have real benefits on certain types of terrain.

Very true- difflocks tend to do one two things when you're slightly stuck:

1) Get you out.
2) Dig you in even deeper! Usually up to the axles if you're not careful- recovery then involves winches and other vehicles.

Difflocks (by bitter experince) need to be used with care and only applied in the right situation. Also, especially on older LR vehicles, it's all too easy to snap a halfshaft if you're a bit to 'enthusiastic' with the throttle!

70 series crusiers over here have factory lockers front and rear as an option.

I disagree with some of the comments above. Lockers make a vast difference in a lot of conditions in my opinion, and if nothing else allow you to do everything much slower than you could do otherwise.

Which of the modern 4x4's come with difflocks ( front or rear or centre ) other than the Discovery 3 and the Ranger rover's ?

Something like a Jeep or Toyota that is part time 4WD, meaning its 2wd until you select 4wd

I have to correct you there,
Since when where the Land Cruiser LC series (pictured)

part time 4 wheel drive?
All the LC3, LC4, LC5, Invincibles, are all permanent 4 wheel drive.
No option for 2 wheel drive.

'vette

ok thanks. Although Toyota do/have made more than one 4x4. Hi lux's are 2wd/4wd aren't they?? I admit its been ages since I went in one.

[uk_vette]

Hello 300,

yes, just so many combinations

So many Toyota's 4 x 4 and 2 x 4 part time, selectable, full tine, rear locks, rear and front locks
They probably make every combination considered !

Most Zuki's don't have center diffs that's why they use 2 wheel on tarmac ( new vitara different).
Some Jimmy and V6 GV's have LSD's on the rear.So front and rears axles are locked when in 4x4 mode.

You can get bad transmission wind up if you use Zuki's in 4 wheel mode on tarmac

Man, those little Zuki's are agile.
For a lightweight 4x4 they really are good.

is the vw actually a good offroader? vs a disco?

My understanding is, yes, they are very good indeed off road. The right tyres are obviously key to most off road scenarios rather than reliance on locking diffs and traction control etc. Lower models of Disco III did not have a rear locking diff but it used to be an option (when I bought mine it was - don't know about now) and it was standard on the HSE, making it very capable indeed if large and heavy.

The real skill in offroading is to maintain momentum and lockers can be a major aid to this. Don't view lockers as a "get me unstuck button" but try and have them engaged in sufficent time to prevent a complete loss of momentum. Obviously lockers that can be used "on the fly" are the better option. My G Wagon although very heavy can be kept moving through the worst of terrain by judicious use of its three locker system, which I imagine is what Mercedes intended. Obviously if you don't have off road tyres then your progress is going to be a bit limited.

Never a truer word said. Don't view lockers as a "get me unstuck button"

I agree, but sadly we can all use lockers, some competitions don't allow them.

So if your truck has them are you not allowed to compete? Or do they trust you?!

what about fancy TCS systems instead ?

Mitsubishi L200 Rear diff lock (button by the handbrake, only works in 4wd)

[SystemParanoia]

lol thats a shame

Indeed, i'm working on a fix because in the rain it's brilliant fun to find a roundabout, but as it's an open diff once 1 wheel goes light it just spins up.

[SystemParanoia]

yeah, the cure for that is to shift lock, and carry a bit more speed.

that free's up both wheels nicely

Yep if its factory installed. I suspect you could fit it in the modified class, but it'd be a lot of work to an older vehicle.

Yup ... if LR were "designed" they would have mechanics with diffs that worked and lasted but instead some of the UK thinks the diff locks are hardcore dangereous stuff ... (runs and hides now..) Meantime LR had soft suspension travel which does compensate sometimes instead if you can life with it on the road. Real 4x4's come with lockers front and back from factory

So .. does the Unimog have the treads on back to front at the back.. to get you back out again.. or is it full steam ahead and go for broke with threads the right way? Diffs are the reserves.. get you going again when backing out or to get you the last few feet if it is attainable/up hill.
