Troubleshooting Diff Lock Issues

[Maxhead]

Guys, I remember there was a couple of threads about post 2012 patrols with rear diff lock not engaging

I can not find any at all

Any one remember the issue or can help me search?

Its holding up my current sale unfortunatelly. Its booked into Nissan on the 18th but i would
like to resolve the issue before then.

Basicaly, when i turn the rear diff lock on the light flashes and wont go solid to say its engaged

Cheers

Only thing I could find is the following .
My understanding of the e-locker is that it dose use the original ring gear and pinion gear. So if the factory diff lock has different specs to the LSD, which the e-locker has been adapted for it won't fit. As there is an e-locker for the front and a different one for the rear, they don't have one for the factory diff lock which makes sence. That could be a reason for it being incompadable. As for your factory locker, when I got my patrol I found that the diff lock wouldn't work. I was given advice just to tap the diff housing with a hammer to free things up a bit. I must say I gave it a bit more than a tap but it has been working perfectly ever since and I actuate it a least once a month just to keep things freed up.

I'll give that a shot tomorrow. Cheers

From memory I remember some connector being loose as well so I'll check all that too

It's normally the vacuum solenoid mounted on the passenger side firewall that fails. It's worth while checking the wire that runs down to the rear diff, make sure it hasn't been damaged or cut in two.

The problem with mine was it had stripped the teeth off the diff lock assembly inside the diff.

Thanks Rod, I'll have a look. Any chance of a pic mate?? Please best buddy...lol

Was it a big job in your case? Mine is still under warranty so I could be lucky but as you know Nissan is a bunch of pricks..lol

What do you want a picture of? the vacuum solenoid?. I don't have the remains of the rear locker apart from some loose teeth. I've heard some people were able to get warranty and some people weren't able to get warranty with the stripped teeth. I just went for an E-Locker replacement.

The first thing I would check if was I was you would be the electrical wire and vacuum hoses that run down to the rear diff. Then check the vacuum solenoid operation.

Yeah I was after the vac solonoid pic but I'm pretty sure I found it.

I was actually thinking it was an electronic locker from day one till I saw all the air lines

Thanks Rod, ITs ganna go either way

I can get of photo of it if you like. Just let me know if you need it. It's mounted to the firewall just below the LHS bonnet hinge.

The vac solanoid looks ing good shape, like new really

This is the bit I'm worried about as it's a bit out of shape

It’s a bit hard to tell by the photo, what’s a bit out of shape? The whole unit where it mounts to the diff or the connection of the bottom vacuum hose.

The bottom vacuum hose is for diff lock off. The top vacuum hose in your picture is diff lock on.
