Is there such a thing?

today i bought a GQ SWB petrol/gas and below the stereo ( factory one ) there is a factory switch saying, rear diff lock. ( on/off ) and u turn the know one way or the other depending.....

was just wondering if this is for real and are they any good?

cheers

Yes for real... yes they good.... if used appropriately


heaps ofg threads here about them.... mine works fine but you need to turn it on once you go offroad, not 10 sec before the obstacle of choice like an airlocker - they take a very long time to engage and disengage.

yep mate of mine has one best thing to do weld a gaurd around the actuator on the rear diff very expensive to fix

weld a guard ya recon?
Ill have a squizy and check it out.


Beastmavster,

so when u say put it on when u first go offroad wat do u mean?

when its on it works like a detriot?
or auto locker?

or is it on all the time but wont come on till u lose traction?
how does it work?

cheers

what he mans is they can be very slow at times, so you may as well have it on all the time, they are know where near as quick as an air locker, ive also heard to unlock you may need to swerve a bit to help it out,

as he said, nothing like an airlocker, if you get stuck, you cant just turn it on, as it wont engage straight away, so if you start to try and drive it will engage with a bang

thats what i came up with reading into the above posts.

O well, factory locker is betta than no locker at all

They can take a while to actually turn on and off - they're vacuum driven and can tacke a few hundred meters to turn on, and far longer to turn off.

This can be sped up a bit by swerving the steering wheel to force differentiation. There's only 4 points at which they can lock in from memory, so you need potentially to get the left wheel and right wheel to turn up to 90 degrees different before it will lock in.

During this phase you shouldn't exceed something like 10kph. I'd just say go slow and maybe swerve from side to side a bit till it locks in.


Disengaging is worse.

Not like an airlocker with it's push button convenience, but far less likely to blow seals and leak oil.

However they are very tough if not abused (eg turned on suddenly while driving at 80kph would constitute abuse) since the force given to it to lock the first time you went around a corner would probably be enough to snap your diff in two let alone bust the locker. Obviously this would kill an airlocker too.....

Usually a breakage will be a electrical contact problem, a busted line or a solenoid issue. Unlike an ARB air locker these things are designed to last a long time - most of them still work fine with no servicing after 200-300,000kms......



Heavily lifted vehicles would leave the locker more exposed if the diff is rotated.

My best description is treat it like a welded off road - turn it on and leave it on... but like an open diff offroad.

Best of both worlds really.

theres'a thread on here a few pages back where someone suggested an alternative solenoid which may speed up the engage and disengage.

Way better... seriously except for the speed of engagement these things work really well.

cool sweet as

[quote="Beastmavster"]They can take a while to actually turn on and off -

true but ive found turning on is much quicker with mine max a meter or two then turning of can take a few mins....


but work great and as above protect them

Howdy

My SWB Mav has the factory diff lock I have found that gently turn left and right while driving when either turning on or off will help to engage or disengage. Mark Cheeseman ( Cheezy Racing ) has also advised the same. You will also need to make a protection plate for the actuator on the diff very expensive to replace if busted.

try searchin for info, WOOP has posted heaps of info on the good/bad on these before.

The rig is only a daily driver / tow rig, but was just curious about them as it has one
