Hi all
I'm looking for,a cheap rear diff 3rd member, to suit Dana 70.
Going to,try and fit my Landrover ARB air locker to it.
Might not work out so dont want to wreck my existing diff.

Oz,what do you mean by a third member,Dana 70 is a Salisbury type diff so technically is a diff carrier at least that is how I always knew it,the third member is what carries the pinion and crown assembly but that fits in a Banjo style diff

Landrover Salisbury diff is (was) a license made METRIC Dana 60. The Oka's rear diff is a Dana 70 which is bigger so I'd be real surprised if it fits.

I better have another look at this.......

The Landrover had both types, and I know the Salisbury is a right pain to remove crown gear

The Dana isn't too big with everything removed



This one off a F359, same ratio 4.88

Says its Model #3

OKA is Dana 70 U

Anyone point me in right direction ?

Would OKA hubs and axles fit ?

Whilst it MAY be possible to fit the Landrover Salisbury ARB centre to the Oka carrier assuming the crown wheel bolt holes and PCD match up the side gears will be some horrible Landrover low spline count and will need to replaced also.
IMO you'd be better off to sell the Landrover ARB kit to a Landrover person and get the right Dana 60 kit for the front and fit a Dana Spicer LSD for the rear.

Oz as Deano point it out I think you are heading for a lot of headaches and expense,the Land rover hubs depends on the Spindles that you will weld at the end of the tubes,I don't think off memory Land Rover carrier will fit in a 70 ( but I'm not a Land Rover guy) The 70 doesn't look too big when bared but it's bigger than a 60.

You guys are probably right.

Found a 4.88 housing , no axles for $200,
Maybe next year I will re-examine this again.
The Ford 350' rear is fully floating like the OKA ?

The rover Salisbury was smaller and the carrier a squeeze.
This Dana 70 looks ok to get stuff out of the housing.

Are OKAs LSDs on the rear ?

It was an option, 374 has one and like others have reported it works very well, having had lockers in previous vehicles I wouldn't bother with a locker, the lsd is fine.

OKA 374 LT Van, converted to camper/motorhome,
400ah Lithiums, 1100w solar, diesel cooking heating and HWS,

Agree Peter
My OKA a problem in sand, I think the LH fwd freewheeling hub needs an overhaul.
I must have a slipper on the rear as the rear wheels barely spin when it was stuck in sand.
But the aggressive michelins quickly dug a hole.

These lock rights seem well priced, but I wouldn't bother replacing a LSD with one.





The rover Salisbury required a spreader to install the ARB locker,
The Dana 70 is big enough by the looks.
But I probably won't bother, truth is the PTO,winch is the best backup plan

We replaced the open front diff on Oka 148 with a Spartan Locker a couple of years ago (Dave and Pauline did the same on Oka 137).

The Spartan is very similar to the Lock-Right design and was a bit cheaper at the time.

On our joint GSD crossing (with Dave and Pauline and Deano and Kaye) the Spartan did its job well, pulling us up and over very soft sand.

Only on tight cornering did the steering become extremely heavy, which must have placed a lot of stress on the drive shafts and hubs, but no damage was caused.

An LSD would probably have been a bit kinder, but it would/should still have locked up with the same stresses on the drive shafts. Having also fitted an LSD to the rear of our Oka, the front locker was a much easier job. No setting up is required since the carrier is reused.
