Ошибка ниссан патрол diff lock

The story goes that my Patrol is back at Mr Nissan for the 3rd time in 4 months after the rear factory locker failed during a recent Earth trip to Terowie 4×4 Park. Had told them when took it in that I have had enough with the crappy/flimsy/poorly designed factory unit and want it replaced with an E-locker and I am happy to waive warranty on the diff through them as the E-lockers come with a 3 year warranty. They were very open to the idea and left it with them along with details of who and where to get it done.

Finally heard back from Nissan today that they do not make an e-locker to replace the factory unit nor does ARB do an air locker either (not that I really wanted an ARB unit anyway) so they will be repairing the factory one again. All this sounded a bit odd so thought I would go have a chat to the company that would have installed one if they could (Pro 4×4).

So the reason why they don’t fit as replacement to the factory one as we all thought they would is that although the diffs are the same size is because the carrier bearing on the factory locker are a different size to those in the LSD’s but other than that everything else is identical. You cannot get hybrid bearings to mate the e-locker carrier to the factory locker centre. The only option is to get a second hand LSD centre and put the e-locker carrier and my factory crown and pinion in it. Would be looking at an extra $500-750 for the diff centre even though I really only need half of it. Technically I really only need the bare chunk of cast iron that is the centre and the rest off parts would be mine + the new e-locker carrier but doubt I would be able to find just that or an LSD centre with a totally shagged LSD throw away.

In future will only use the locker maybe in muddy, slippery uphill/downhill conditions where traction is limited anyway and doesn’t put max load/torque through the locker and on everything else just let the ABS do it’s thing using the brakes to stop the spinning wheel front and or rear and transmit drive to the other wheel that has traction which works just fine and basically turns both front and rear diffs into LSD’s. Downside of that is a little more wear and tear on disc rotors and pads but at least is a ship load cheaper to replace those than what would add up to nearly $3k to retro fit an e-locker due to extras required to do the swap now.

Have a chat with these guys http://www.precisiondiffandgear.com.au/services
I was going to have them overhaul the Prado’s diff.
They knew what they were talking about (but I wasn’t talking lockers) and weren’t too pricey. I didn’t end up having the diff done cause I knew I would be selling the car, so I can’t vouch for workmanship.
I’m not sure if these guys would be able to help, but I just thought I would put them out there

Cheers

Thanks for that guys. Will just have to see how it all goes from now on and as said use the locker sparingly and only if all else fails and only in certain conditions. As you have said Les, the main reason for putting this up was for others info and should they be considering the same thing down the track should their flimsily designed Nissan Factory locker fail the same way mine has. I thought all was gunna be good as my original plan was to just splice the e-locker on/off into the original dashboard switch, remove the actuator fork from the actuator inside the diff so as far as the car knew it was still running the factory locker. Just unfortunate that the diff centre is a slightly different design than non locker versions.

Thanks for the info John. I have actually dealt with that mob before a couple of times when having an M21 aussie 4 speed and banjo LSD diff centre rebuilt for the XU1 I owned many years ago. Yes they do know what they’re talking about and did great work but aren’t cheap, well they weren’t back then and they did treat me like a bit of an idiot at the time and tended to talk down to me. It may have just been the person I dealt with at the time but they weren’t overly friendly. Things may have changed since then though. They do tend to focus more on the performance car side of things when it comes to work other than factory rebuilds. I got a price for a commodore borg warner diff conversion to fit an LX torana a little while back and believe me it wasn’t going to be a cheap exercise. I could have actually done a ford 9″ conversion cheaper but just didn’t need that much extra strength nor did I want the extra weight that went with it. In the end decided to stick with a banjo LSD which as long as you don’t go doing redline clutch dumps will handle a fair bit and after all, they did run them in all Bathurst toranas from LC all the way through to LX’s including the L34’s except for the A9X which although is an LX actually has a UC floor pan which is why they ran a Salisbury/BW diff and is why it is virtually impossible to clone/fake one of them.

Cheers Gav,
You definitely have more experience with them than me.
When I went in, one of the guys spent the best part of an hour with me going through the options for upgrading the diff and ball park figures for each. They were ball park figures, which a proper quote may have been quite different.
But they are an option for people to chat with them and make up their own minds

No worries John. Would be interested to hear what sort of options they put forward as far as upgrades go and what sort of ball park figures they were talking about for them.

Finally got the Patrol back today after a month of waiting.
Lets see how long it lasts this time, which should be a while as I won’t use the bloody thing unless I absolutely have to….lol

Meanwhile on the hunt for a shagged LSD centre, may have one lined up fingers crossed.

I have Bort a new Nissan patrol y61 in Aug 2015 had it back to the dealer 3 times already for the rear diff lock not engaging or taking up to 5 mins to lock in.
I have heard of a product from a company call Mac this is a replacement solenoid to fix your factory locker for ever,I will keep you updated as iv asked for some information to be sent to me.My freind done this upgrade and tells me the factory diff lock lock in ,in about 2 seconds every single time… he loves it but hes patrol in 4 years old so im hopeing that the solenoids are ok for my 2015 patril.

That’s awesome mate, thanks for the heads up. The issue is not really with the solenoid itself. Have read about the solenoid replacement elsewhere. It may fix the time it takes to engage but doesn’t fix the inherent weakness of the locker itself. I get the time it may take to engage due to the solenoid is an issue but once it is engaged and it fails is a whole different story. Replacing the solenoid will not technically «fix your factory locker forever» just how quickly it engages. I personally wont bother touching the locker switch unless in slippery mud or snow or basically anywhere the chance of little traction may be on either rear wheel. Knowing now how the electronics side of things work am happy to let it do its thing knowing it is doing it on both front and rear axles. Even Nissan themselves have now said that the fact I run a 33″ muddy and the extra traction on force it’s putting on it is too much for it to handle. If you do some searching on what they look like internally you will see what I mean.
