Diff lock - how do they work?

[sam]

This is I believe is slightly misleading when they say " Hence it all turns all the time."

Yes the front drive shafts DO turn all the time and what they say re this is correct but to say it doesn't cause excessive wear is debatable as if you run most of the time in 2wd then having your front drive line spinning all the time due to the locker has to cause more wear and most likely slightly more fuel consumption.

If you normally run your ute in 4wd ALL the time then they are correct it would cause no additional wear

[NowForThe5th]

True, Sam, but this is the case without the locker, i.e. standard diff, as well, as I understand. In 2WD the right shaft spins all the time up to the disengagement clutch while the left shaft is connected all the time right through to the prop shaft. What they're saying is that the Lokka would cause no additional wear and, in fact, given that their gears engage solidly, there would be probably less wear. I've never heard of a Triton wearing out diff gears and Lokka give an unlimited kilometre warranty, so I don't think it's an issue.

Get a group buy price Chris..

[sam]

I must be pretty useless at explaining things so I'll just say with the standard disengagement system in 2wd the front drive shaft (prop shaft) does NOT rotate and hence the transfer box doesn't either but if you install a Lokka it will rotate ALL the time even in 2wd.

rock o.

looks like your dog could do with a diff lock for those ears (very cool dog though)

the factory diff lock is not electric - it is air operated.

i agree with Homer, if you only have TC see how that goes first before spending a heap on lockers. i went locker on the ML because there was no TC and for $700 it was a bargain. there is probably plenty of other things to spend 2+ grand on first, like suspension, tyres and the list goes on.......

Not too sure about that - no compressor, no airlines, only electric wires entering the diff housing!

Don't you really hate that? Getting shot down in flames on your first post? I'll be gentle.....

"Mobile2 your last transmission was garbled. We thought you said that Triton factory diff lock was not air operated. Mobile2 please refer to previous communiques. Air operation was confirmed after detailed investigation about 4 years ago.

"Mobile2 please Roger. Base out"

Frankly I'd be surprised if I found an airline entering my diff. Unless it used Tardis technology you'd never get a 737 in there, let alone one of those bloody big A320's. Airline? Oh, air line.........

Welcome Mobile2. You've had your initiation razzing.

The standard TC is pretty fantastic...It will get you trough most stuff...You cant fit the factory locker afterward...

I would just run with the ATC...If I had spent hours trying to dig the Triton out I might feel different but cant see that happening...

The only Triton with a LSD is the GLX without the factory optioned ASC/TC...

[Naff]

Anyone read the lasted 4WD Action mag? Has a good write up on a bunch of lockers - manual and automatic.

Has me leaning more towards a manual one like ARB (front).

[daryn]

Father in law is on his 4th Detroit locker in his 70 series single cab.

If I did it would be manual too Naff.

When the factory ML diff lock is on does the air pump run continiously until it is turned off, or does it run only to engage it?

If it runs continiously, will it overheat/fail if vehicle is left with diff lock engaged for a long time?

[sam]

Only runs a very short time to engage

[snowman]

brunopezz,

do this and you will hear it. with the engine running place your car in 4x4 low. then turn off the engine.

then turn on the ignition (don't start it) then turn on the diff lock. if it is quiet you will hear the comp run for maybe 2 seconds max.

don't forget to start the motor before taking it out off 4x4.

[daryn]

It should run just long enough to get the required pressure in its lines and tiny tank and only turn on if pressure has dropped.

Can the factory type electric diff locks be fitted after market,

Not sure this question was answered, but "No" is what I was told when I asked to add them (my car was already here)

i checked this out and was quoted $4000+ to have it fitted afterwards, as they have to replace the diff complete

Welcome Mobile2. You've had your initiation razzing.

I wasn't refuting the claim that it was air-operated, just seeking clarification based on what I can see under the vehicle - was not here 4 years ago. A quick bit of further research on my part shows that it is indeed air-operated, but any links to real info on how this diff lock works would be appreciated. Had assumed it worked the same as Toyota diff locks which use electrics to engage a locking collar, apparently.

[Naff]

Yeah just an electromagnetic coil I would imagine.

Probably a dumb question and maybe posted on here somewhere but I couldn't find it. I have a 2014 MN GLX and toying with a diff lock, (undesided front or rear yet). So, here's the thing...if I have one diff lock engaged and I lift a wheel will I lose all drive to that wheel?

[L200Shogun]

That is what a diff lock does. Sends drive 50/50 to each opposite wheel.

[4wd26]

no that is the purpose of a cross axle diff lock

what happens to one wheel (rotation) happens exactly to the other (front diff lock both front wheels turn the same) and the same for a rear diff lock

so with the centre diff locked you effectively have 3 wheels turning together if you have one locker

with twin lockers engaged all 4 wheels turn together

[albee]

Thanks guys. I was sorta unsure whether the GLX has a centre diff locky thing and what part that plays on it all. I know how the diff locker works and am actually looking at an e locker but as I said I'm unsure on the centre lock. My Pajero definitly had one so I knew I had at least 3 wheels driving.
Squse me if I seem challenged.

[Cowboy Dave]

Don't worry mate, we're all a bit challenged around here, one way or another.

If the old saying is true that you learn by your mistakes then I should be a rocket scientist.
