If you have an LSD READ THIS!!!

[nj swb]

Hi Blutak, I know its been a while but I've been trying to chase down whether my 1986 NC Paj has an LSD or not. My rear diff has the sticker on it saying to use only LSD oil with an LSD but does this actually mean it is an LSD or is it a warning put on all the paj diffs at that time? I had the rear wheels off the ground and when I spun one forwards the other went backwards so I assumed it wasn't an LSD but after reading your post I have hope again.
Thanks,
Ryan

Did you have the transmission / gearbox in neutral? If the propshaft can't turn then the wheels have no choice but to turn in opposite directions.

To the best of my knowledge, Mitsubishi only put the stickers on LSDs - so I expect you have an LSD.

Please don't try the "drive off a jack" trick either - that's not a definitive "proof" either. My NJ couldn't "pass" this test, but its LSD worked well where it mattered.

Not sure if I did or not but I'll give it another go amd see what happens otherwise ill be following what you did to clean it out and get it going again. Is there a gasket available once I pull the back off or do I have to use a liquid gasket? Bit of a novice and only recently been getting into it.

Sorry, haven't posted in ages!

Easiest way to see if your Paj has LSD is to chock the fronts, make sure the hubs are unlocked, jack up a rear wheel and turn it by hand.

If it is really easy to turn it, your diff is open. If you feel alot of resistance, it is LSD.

Beware, this does not work if your rear brakes are dragging.

The other is bringing both wheels off the ground
If you turn one and the other goes the opposite way, you are open. Same way, you are LSD.

Possibly.

If the propshaft can't turn then the wheels have no choice but to turn in opposite directions.

For those browsing "New Posts", or having success with the search function, please note this is the Gen 1 forum, discussing clutch-type LSDs. Helical LSDs as used in late Gen 2 onwards behave differently, so the tests described here don't apply.

Hi Blutac, good work..
Your first statement about your old NF going down like the Titanic on both ends sums up the behaviour of my 1989 NF import... I would have thought it was LSD at the rear, as the diff housing is massive and nothing like my 1988 Shorty Turbo diesel...which has a conventional open wheeler.

The 89 is four speed auto with a coil rear end, drum brakes. The shorty has discs on the rear and again is coil.... ??

It's really annoying that as far as I can tell the rear is behaving like an open wheeler.... I have changed the diff oil a couple of times, once when I got it and again, 2 years ago when the right side axle seal let go... oil seemed Ok apart from it being 500mls down at the first change.. I used Castrol LSD oil..

There is no label on the diff... but shouldn't it mention it on the build tag under the bonnet ? otherwise how do you tell ?
Being an import the NF it is a little different like having 4 speed auto a year earlier than domestic models and no oil cooler..

My 1990 NG has a sticker on the drivers door but not sure if this is consistent between models. Pajero LSD

If it's behaving like an open diff all the time, it probably is one. Or the clutch packs are worn out. You may be able to call a Mitsubishi dealer and give them the VIN and they can probably tell you if it has a LSD or not.
