Diff locker options???

[gen1pajero]

Hi there,

I have a 1990 Gen1 SWB 3.0L petrol model. Im looking at getting a rear locker but need some direction... what brands/part numbers etc are there out there?

Thanks

I have a ARB Air locker in my 3.0l SWB NK

Thanks, do you have a 8" 10 bolt rear diff? Also where abouts did you get it from? im in NZ and am having trouble trying to source any ARB stuff.

Cheers

Would of thought you had the 9" rear diff as its the V6

This is ARB's application list. Mitsi is about half way down the list.
I don't know who else does a rear locker for Pajero except China.

If you reckon you have the 8" rear though, try this

personally i think you would have the 9" though

hi guy's
yes all gen1 3.0v6's LWB & SWB have 9" rear diff with coils and 8" front diff
the gen2 like xrrob has uses a bigger 9.5 inch rear diff with a wider track than the gen1 3.0v6 and you can get a rear air lokka for them from factory & arb from the info i have found
you can get arb air lokka to suit gen1 8" front diff here is a copy of listing for gen1&2

ARB list
Montero, Raider,Front 1989 on IFS, 28 spline, 8.00" RG 28.8 (1.13") 28 All RD1104
Pajero, Delica (van) ,1984-97 IFS, 25 spline, 7.25" RG 25 All NA
Shogun Rear 1983-86 8.00" 10 bolt RG1 30.5 (1.20") 28 All RD05
1987-95 9.00" 12 bolt RG2 30.5 (1.20") 28 All RD463
1993-00 3.5L & 2.8TDI, NJ,NK,NL, 9.5" RG, live axle 33.6 (1.32") 31 All RD154

i am looking into doing this myself in the future when funds allow and fit a gen2 rear complete with the rear disk brakes and the stronger gen2 rear control arms preferably with factory diff lock option if i can get one at that time but that's a way off at the moment

in the mean time a mate has got a 8" rear lsd that i plan to try and fit the internals into the front diff center keeping my own crown & pinion so as not to change ratio's i have heard of this being done in the US on 4x4wire
the front diff will then be better than the std front diff and will cost me very little to do myself just time and one of my spare front diff's
if i had to pay someone to do this it wouldn't be worth the cost it would be better to wait for the air lokka to save spending the money on a front diff rebuild twice

also some more info if you have the v6 auto the front cv's are not as strong as they are in the manual so when you need to replace then i would get the manual cv's i have yet to remove the auto cv's to compare with the one's from the manual
i found this on 4x4wire just can't find the link to it i guess genuine part numbers would tell if it's true

9.5" I think.
Got mine from opposite lock in Newcastle NSW.

[gen1pajero]

In the rear of mine im pretty sure its an 8" as it only has a 10 bolt set up rather than the 12... il have to take apart and measure it up sometime soon

[Barneymutt]

I think you'll find the number of bolts referred to is the number that hold the ring gear on, not the carrier assy. I could be wrong tho.

yeah i'm positive it not the housing bolts but the crown wheel bolts you can count them once diff center is removed

it should have the 9" diff coil rear as this was the only rear diff and suspension set up that Mitsubishi used on the gen1 v6 if it has coil rear suspension it is the 9" diff with the 12 bolt center if it has leaf spring rear it's the 8" diff ok just look up the info

Pajero tech data base in the general info section of the forum has the info that should help you identify your diff's

here is the link

Axle Data

Gen 1

2.6, 2.3TD, 2.5TD & 2.5TDI (some) :-
front axle = 25 spline, 29mm diameter, diff = 7.25" diameter (low pinion)
front axle = 28 spline, 29mm diameter, diff = 7.25" diameter (low pinion from an L300)
rear axle = 28 spline, 30.5mm diameter, diff = 8" diameter
3.0V6 :-
front axle = 28 spline, 29mm diameter, diff = 8" diameter (low pinion)
rear axle = 28 spline, 30.5mm diameter, diff = 9" diameter

got this from the link above it also has the rest of the drive line info too just have a look

hope this helps

Thanks for all your help!

whats the diff

Is the info / specifications above only related to the manual? also can a manual front diff from NF V6 be put in to an auto? can get one cheap!
