I picked up my Maverick today with a factory rear locker. We cant get it to turn on :(
How is it supposed to work? I turn the switch and nothing happens. The dash light doesnt come on.
I was told the car had front and rear lockers, could the same vaccuum system work for both front and rear? There isnt an air compressor and it doesnt appear to be locked full time.
Thanks guys

Rear is vaccum operated. search for some info in here by Woop on them.dansedgli wrote:I picked up my Maverick today with a factory rear locker. We cant get it to turn on :(

I would go back and ask the dude to show you them working - if not, I'd be asking for $ back.
It sounds like
1) he's BSing you. They didnt come with a front locker from the factory.
2) the rear locker is broken.
#2 is generally a wiring problem, a leak in a vacuum line or a solenoid. If the rear locker is actually trashed, generally the whole diff is trashed.
If it has a big lump hanging off the side of the diff then they probably havent swapped centres and there's a non functioning diff lock in there somewhere.
But I'd be asking for the dude to cough up some $$$$ because you appear to have no lockers at all.
Be aware they do take a little while to kick in. A hundred metres at slow speed in a straight line is nothing unusual - less if you wiggle the steering.
Unfortunately it's a buyer beware thing with private sales.

Thanks for that.
The ad just said it had diff locks. The father of the guy who owns the car said it had front and rear when I asked him. It looks as though it should at least have a factory rear.
Ill check out all the connections for the rear diff tomorrow. I tried engaging it then driving for a bit to see if it worked but it didnt. Maybe a connection has come loose.
Underneath the steering column there is a hose that runs across that section of the dash. Its black and thin and has at least 3 small valves on it. Any ideas if this hose is related to the diffs?? I ran out of light to trace it all the way back to where it came from.
Other than the apparant lack of diff lockers Im very happy with the car. The previous owner took it for a RWC today and the gas tank wasnt up to scratch so he replaced it at a cost of $700 but no cost to me.
I think I have gotten a good deal on the mav regardless of the diff lock situation.

Ok. It's possible that rather than replace the (rather expensive) locker solenoids they've doen some dodgy piping with a 3 way valve.
Note that there is ABSOLUTELY no way that a rear factory locker will fit front, so it cant be a hookup for the front locker.
Front could easily be an autolocker - you'd never know till you locked in hubs, but you CAN safely lock in hubs in 2wd on the bitumen and you'd know if you have any 4wd experience.
The rear has some wirign that is very exposed near the solenoids. mine was rusted out when I bought it but it was a very easy fix.
hope it was cheap with fuel prices as they are as BIG 4bys are hard to move. now is the time to strike to get a bargain.
Of course, if it still is a bargain in a years time depends on if you do big miles or run LPG

Yep gotta love the LPG! I was stoked that the previous owner paid for a brand new tank and didnt ask for any extra cash. It feels like it could do with an LPG tune though. The difference on petrol is pretty significant.Beastmavster wrote:Ok. It's possible that rather than replace the (rather expensive) locker solenoids they've doen some dodgy piping with a 3 way valve.

I paid $8K for it. Its got a body and suspension lift, 200,000kms, 33 inch mud terrains, its an XLT so has the sunroof and power options, lockers (maybe), LPG, safari snorkel, haymen reese towbar, bullbar, spotties and a CB which doesnt seem to work either. I think Ive set it up wrong though.
Ill check out the rear diff tomorrow and see if any of the wiring or hoses need replacing.

i wonderd about a front locker on that mav, forgot to ask though, engauge the rear diff lock in a carpark and drive slowly at full lock to enguage it, you should hear the tyres chirping, that blue pipeing you were talking about didnt appear to me to be a diff lock bypass, id call tim and ask for a please explain quickly

It definately has a rear diff lock, wether or not it works is to be determined. Malfunctions seem fairly common. Im not sure what the go is with the front one.
Automatic lockers like a detroit would be clunky in operation wouldnt they if there was one of the front?
Would it only be activated in 4wd with the hubs locked? I havent given that a go yet.
SWB mav. Some mods.
Just a thought, do these need to be in 4WD for the factory locker to work?
Did you have it in 4WD or still 2WD?
Reason I ask, on my old Paj, the factory locker would not engage unless the SuperSelect ECU detected it was in 4LO. No light, nothing until in 4LO.
Do the GQ/Mavs have something similar?

huh? You knew they were going to sell you the complete car then ask for some crap back? I'd be keeping it all at home until the locker issue is worked out.dansedgli wrote:They have asked for some stuff back that was left in the car so Dad is going to to take the car around to them and ask them how the lockers work. So hopefully we will know what the go is when I get home from work.
The son wasnt around to explain the diff lock thing to Dad today. He is going to ring me when he gets a chance to let me know what the go is.
I had a bit of a look and did some more reading on here.
Should there be a solonoid on the firewall as well as the one on the diff? There is a solonoid on the rear diff. There is no solonoid on the firewall.
The 2 vacuum hoses come out of the vacuum canister, enter the drivers compartment where there are 3 blue valves, 2 on one hose and 1 on the other. The hoses then loop around and go back into the engine bay where they join onto the copper lines and run to the back of the car.
Can anyone see what he has tried to do?
There is also a fatter vacuum line that has been blocked off with a bolt near where the vacuum canister is. Im assuming this has something to do with the solonoid that should be on the firewall?
Does anyone want to have a stab at how this is supposed to work and why he has plumbed it all up like it is? Lets ignore the front diff lock for now.

My bet would be that the do-hicky (soloniod?) on the firewall with the adjusting valves farked out and he has rigged up something else.
The standard rear lockers seem to be very prone to damage when they are rushed to engauge. So its probably burred over and cant engauge so he MAY havet tried to put more pressure into the system.
From memory when I took mine out no amount of vac pressure would have kept it locked, but mine would engauge but slip with a clunk.
Also Beastmavster said that if it didn't have a big lump hanging off the side (actuator?) the centres hadn't been changed, when I put the arb in mine I just cut the guts out of this and put it back on to seal it back up.
Air lockers are a real novelty after having a vac locker

I've got one and had same problems! They will engage in 2wd!
1st I turned switch on with 4b running and got under 4b, took off vaccum line 1 at a time and checked for suction. When switch is turned off suction shouldv'e happen again. But nothing happened! So I got under 4b again and swapped lines over, went forward 5m turning at same time and diff lock eneaged and light came on. So what I worked out evently was someone mucked around with lines previously, but had no luck fixing it. So I mucked around with the solinoid in the engine bay and found one side didn't work! It was easly fixed by going down to the wrekers and geting an old single vacum solinoid off an old Holden. Hooked it up and the locker has worked since. (Until I did Rope rd a while back & drove in one of those deep murky holes and got a nice size log jammed right up where those wires hang, cutting them in the process,but not the vaccum ones. Wires do jac, just turn diff lock light in dash on, Locker still works fine.)
Hope I helped!

I found that the factory locker is not instant, mine seems to engage when needed or when one of the tyres lose traction, then disengage once switched off, again not instant(sometimes taking a bit of tme), I try backing up or speed up and then back off (hopefully releasing pressure of gears). Have also found that the more use it gets the easier it seems to engage/disengage. On sand its seems worse sometimes. Mates have had problems with the solenoids as well, the local auto elec has used solenoids out of air conds I think (cheap). The solenoids are located high up on firewall next to passenger bonnet hinge. Hope this helps ya mate.

Success!!!!
I had a bit of a play with the solonoid at the diff to see which hose gave vacuum when the switches inside the cabin were turned.
Instead of having the 2 solonoids in the engine bay the previous owner has rigged up 2 irrigation hoses than run from the vacuum pump, into the cabin and back out to the diff.
The 2 hoses have garden hose variety valves on them inside the cabin. By switching one open and one closed at the same time changed the vaccuum path.
All the factory switch does now is allow the diff lock light in the dash to be turned on when the locker is activated.
Side to side steering turns it on and off nearly instantly.
Thanks for your help guys,
Dan

I thought of that just after I figured it out. I hope I didnt do any damage to it when I was driving the car with the switches in who knows what configuration. I only did 80kms so I think it should be okay.bazzle wrote:Good news.
Remember it requires vac to hold on and off. ie. Must have vac on one side of actuator to turn on and vac swapped to other side to turn (hold) off. Dont run it with no vac.

Nah, I have a feeling that the Dad got the front locker confused with front hub locks. I asked him on the phone how the front diff lock was activated and he said that you turn the locks on the wheelswrksux wrote:worked out the front locker yet?
The son is going to ring me to tell me how the rear locker works so Ill ask him about it then. Im suspecting the Dad made a mistake.
Im still happy with the price I paid for the car. It was cheap and is in great condition.
Its got a nice long range petrol tank in it too. Does anyone know what this would hold? I think its aftermarket as it has a sticker from some long range tank making place on it.
Im going to the bush tonight to test it all out. I cant wait!

Most aftermarket replacement tanks are about 130-150lts. My LRA tank is supposed to be 147lt. But I think it is more like 130-135lt.
