What ARB locker to rear?

Axel Von Gardan · 04-07-07, 11:13 AM

What ARB locker goes to rear axle to LJ70 -90 and newer?
I´ve been telled that theres 8.9" rear diff and RD33 would fit, but ain´t RD33 to 9.5" diffs?
At front I´ve got RD23, works fine. But now I should to rear and I liked to be sure for what am I buying.

an 8 inch . i think it is the same as the front maybe the RD23 will work, there very little info on the lj axles

If memory serves me right you need a RD08, the LSD carrier on an LJ70 takes the same bearings as the "V6" or "turbo" trucks.

Yeah well... I bought that RD23 to rear until I hearded that it wont fit to rear axle, so I installed it to front.
Havent even cracked any joints
, theres bigger joints than at older LJ, allmost big as HDJ joints.
Here I wondered will it break but luckyly it didn´t

They dont even knock at all.

So you got 10 bolt diff, I think that this model got 12 bolt 8.9" diff...
Maybe I´ll take my risk and order that RD33

the 12 bolt 9" RD33 will work in a 40 and 60 series but defintealy not in your LJ70 unless it has some sort of hybridized rear end.

It was fine, never had any better things to do at hangover...

RD23 has now installed.

Hi,
Out of interest I have a KZJ70, probably the same axles as the LJ70, did yours have an LSD fitted in the rear?
I am looking at putting a arb in the rear, suppose this is the RD132 as well?
Any comments to help on my install would be much apreciated?

Thanks
Martin.

WojtekSz · 05-29-08, 04:07 PM

Martin,
I also ride a KZJ70 and will install RD132 in both front and rear.
I have checked that RD132 is the thing we need for out trucks: 8" 10 bolt rear diff and high pinion 8" 10 bolt front diff.

Cruiser70 · 08-10-08, 04:18 AM

Hi,
Thanks for the reply, only just seen it.
I will go with RD132, getting some knoks and chings from the back end so may as well swap it out for a locker.

WojtekSz · 08-11-08, 02:58 PM

Tapage:
