LSD Ratios

[BogBoy]

Hey

Bidding on a LSD rear end and I hope its the right ratio

How many ratios are there?

[Dirtydog]

depends what it is.

between safari and terrano i know of these ones:

Safari:
4.625 (safari spirit 2.8 turbo diesel, rare)
4.11 (standard)
3.9 (petrol ones)

Terrano/mistral
4.88 (some diesels)
4.625 (standard diesel as far as i know)
4.375 (unsure what these are in, think later terranos and v6)

i think there were some 5.?? in some of the 4wd vans too.

[BogBoy]

This is the one I brought

Will pick it up tomorrow and hope like hell its the same.

I emailed the guy before hand and he said it was out of a 1992 D21 auto turbo diesel.

[Dirtydog]

most likely 4.6 or 4.8

4.625 is most common in those years. You will have to pull the diff head out and look for the stamping on the crown gear to make sure. Good thing is they only take half an hour to do, if you know what you are doing. Only need to slide the half shafts out a little way to release the head

Cheers,

Can i tighten up the lsd using more shims?

I was going to put new bearings in it too. Just give it a complete
over haul

[Dirtydog]

You sure can, new shims from nissan are around 120 for a kit from nissan. Also read somewhere you can change the shims around to make it tighter too.

When I bought my LSD (4.6), I just swapped the crown gear off my old diff(4. into the LSD diff to keep the ratio's the same. It's the spline count for the axle shafts that matters.

[Dirtydog]

the earlier ones are 31 spline, newer ones are 33 spline, are the new ones same spline as safari axles?

[BogBoy]

Sweet so even if the ratio is off I can use my pinion wheel?

afaik you should use both your crown wheel and pinion as they are a matched set

[Dirtydog]

yeap just swap the lsd carrier into your diff head. probably easier that swaping your crown and pinion over.

[BogBoy]

And saves me over hauling the whole axle too?

How tight can you get the LSD's?

Im wanting it close to a locker.......

[Dirtydog]

if you put in extra plates you can get it really tight, but if your after a locker weld your diff, cheaper, easier.

the problem with using extra plates is they will wear over time.

[BogBoy]

Hmmm so weld one diff and have one lsd?

[Crash bandicoot]

or you could look at acquiring the diff from a 1992 R32 nissan skyline GTs-4 had factory 2 way LSD

They are the R200 LSD? I already have one but I have brought a whole axle for the 4wd

[nismo26]

What are you trying to do?

[BogBoy]

Me?

I have brought a complete disk to disk axle that has a LSD diff in it

The R200 LSD diff is left over from when I was going to put it into my legacy.

I am wanting to tighten up the LSD to the point that its nearly a locked diff.

Go into Cockram Nissan and get a couple of .7mm shims about $10 each put them in, won't take much to tighten it right up, you will have to set the back lash when you put it back in. Shims out of a safari LSD might fit they have the same size crown wheel and pinions.

Wicked, Now to run the breathers up under the bonnet away from the water.


What oil should I use in the LSD? I was going to use Red line shock proof....

The clutch plates and shims inside LSD Safari, Terrano and Navara diffs are all interchangeable. Can add shims or extra clutch plates to make tighter I have an extra clutch plate each side and my truck almost behaves like it has a locked rear diff. However as others have pointed out the tighter you make it the faster it will wear.
