Hi All,

I have a quick question about the the rear diff on a 2005 Patrol. I have a UK spec patrol and i want to know if i have the LSD. In the brochure for the car it says "Limited Slip Diff (Diff Lock)". Does this mean the car has a LSD AND a Diff lock. I have the Diff Lock button on the dash board. How can i tell if i have the LSD, does it look different from the standard diff?

Thanks for any help.

Scott

LSD and Diff Lock are 2 different things......AFAIK you can't have both in the same pumpkin.

The way to tell if you have a diff lock is to jack one rear wheel off the ground, with vehicle idling (be VERY careful) and in neutral, press the "DIFF LOCK" button. You should find that you cannot manually rotate the raised wheel..........but with the switch turned off, you SHOULD be able to rotate the wheel.

If you have a LSD, you should be able to turn the raised wheel whatever the position of the button.

Hope this helps

Cheers

It would be very hard to turn!!!
The LSD, if it is working properly, will feel like a locked diff if you're trying to turn it by hand.

hl,

The raised wheel may be "very hard to turn" as you say (if it has the LSD fitted)......... BUT I believe it would be 'impossible' to get ANY movement whatsoever from the raised wheel if their is a diff lock in operation.

The diff itself would, presumably have sort of physical evidence of diff lock being fitted too....eg: a air/vacuum hose fitted in addition to the normal diff breather hose.

Cheers

Hi,

Yes, I guess the easiest way is to have a look and see what pipes/hoses are hanging off the diff.
I you haven't tried it, you will be surprised just how tight the Nissan LSD is. It is practically impossible to turn one wheel by hand with the other on the ground, this could easily lead some punters to believe it is locked.

Jack both the rear wheels off the ground at the same time(jack under the centre off rear diff) make sure the front wheels are chocked,then take the car out of gear and spin one of the rear wheels as if the car was going forward,if the opposite wheel spins in the same direction, you have a LSD.!

Scott, as far as I am aware, your Patrol will have an LSD, whether or not you have a diff lock. Although, the UK spec Patrol may be a full-time 4WD I don't know, in which case there will be a button on the dash for the centre diff lock.

Then again, the UK spec Patrol may have a diff lock as well, in which case I'm jealous !!!

It aint fair guys.
The kiwi's get auto box's on the 4.2 turbo!!!
The arab's get the GU in a short wheel base!!!

What's goin on ???

Patrols are part time 4WD all around the world (all models and variants), no "full time 4WD" version is made.

Check out a few oveerseas Nissan sites....

If Scott is in the UK his (patrol) may be our nissan terrano. He could have a LSD and a(center) diff lock button on the dash.How about a photo of your car Scott?

Hi Guys,

Desrey, our patrol is the same as yours as we get the Terrano as well, but the terrano sells in tiny numbers. If you still want i can post a picture of the UK patrol as i think a few things are different, how would i post a picture? We only get two models a S spec and a SVE spec. The S spec has 16" wheels cloth seats(5) and black bumpers, this is my model. The SVE has 17" alloys and leather with 7 seats. I prefered the basic model and with the scrapes on the bumper it has proved a wise choice.

I will jack up the car tomorrow, would do it today but we are having our first barby of the year and i have drank too much wine. But i think it is just marketing crap from Nissan Uk and i will find it only has a Diff Lock but i will check tomorrow.

Cheers

Scott

Just cut a few nuts with the Difflock button off, If you leave 2 lines it’s a LSD if you don’t it’s a single spinner with a Difflock fitted.

Otherwise the method described by Roachie will give you the same out come, minus the fun.

"...I have the Diff Lock button on the dash board...."

You have answered your own question.

The bochure may have been indicated in a "standard (option)" format, ie LSD standard with diff lock optional.

The only combined LSD/Diff locks are made by a company called Eaton, specifically their ECTED line of diffs.

G'day GaryInOz..........

Maybe; maybe not.

I know a bloke who bought a couple of ARB diff-lock switches and fitted them in blank switch block positions; with the intention of 'one-day' fitting diff locks...(it never happened)...hahahahaha..........and BTW; NO it wasn't me either!!! hehehe

Absolute easiest way of identifying if you do have a diff lock is to get on your knees and look for any strange airlines that go to the center of the diff. Being a 2005 model it may well have "non ARB" looking diff lock switch if it was an OE fitment

You can comforatbly rule out having both LSD and diff locks.

From the source (PDF)

http://www.nissan.co.uk/NMGB/en_GB/ebrochure/Nissan_Patrol.pdf

This is for the 2006 model, but indiates there is a standard diff lock, and part time 4WD in a the same bodyshape as ours (and the rest of the worlds).
