Hi Guys,

Has anyone out there fitted one of the Lokka rear diffs to a constant 4WD 80 series wagon.
I understand I can't fit one to the front without putting a kit in the transfer case and fitting free wheeling hubs.
As much as I'd like to spend four grand on air lockers the six hundred dollar rear lokka suits my budget.

ps. I can't get the search thing happening for locking diffs does anyone have any hints.

Thanks

G'day Jethro,
There are various thoughts on Lokka diffs in the rear of an 80.

1. Large and laden vehicles tend to suffer from "bump steer" (for want of a better term) through corners...... the diff being locked drives straight, until it overcomes the pre-set loading, it then "unlocks" and "re-locks". Some consider the movement during this process to be excessive and in some situations to be dangerous.

2. A good alternative to the Air locker diff and with a slight modification to driving style, ie .... ease off the throttle entering a corner and a light throttle application on exiting the corner, have no problems with a correctly fitted unit.

Both tyres on the rear need to be the same rolling diameter, otherwise the vehicle will be trying to drive in a circle due to the locked action.

Hope this helps,

Cheers,
Wayne.

Before I had an Auto Lokka fitted to the front of my 60 series, I did lots of reading on this via the web.
Wayne's 60's comments on bump steering pretty well sum up the experience of most of those I read about when using one on the rear. In particular, there were stories of the effect being very disconcerting on wet or greasy roads and the general opinion seemed to be that while it was manageable, with care, on the rear, it was better just fitted to the front. If you want to follow this further, I found a lot more experience/comment on this issue on USA 4WD discussion spots than Australian sites.

Thanks
They are a great idea if you drive on the farm, but on the black stuff, they suck, they wear the tyres and break the axle studs off, they lockup going round corners up hill, and are down right dangerous in mud and snow, with both wheels locked all the time, you spear off the road as soon as you loose traction. Uneven tyre pressure upsets them, yada yada yada.

I agree with Dozer. I should have made it clearer, the reports, I referred to describe the behaviour on slippery sealed roads.
Been very happy with my auto lokka on the front of my 60 series, but that is a very different arrangement to the permanent drive of the 80 series of course.

Still much more expensive than your $600, but $4000 is way off the mark. Rear air locker (ARB) including compressor fitted for about $1800 is closer to the mark.

Thanks for the help guys, the vehicle is used mainly on the road and the beach so I don't need the extra traction for 90% of the time.

I got stuck going up a hill the other weekend and I'm determined to make it to the top, so I guess I'll just have to spend the cash and start with with one air locker and see if I kill the car of myself first.

Regards

Hi,
I have a 4wd Systems auto lokka in the rear of my 80 series and have had no problems. the only time i feel it un locking is on full lock in car parks going 5 kph.
Mine is still full time and I have not had any negative handling effects.
I fitted a air locker in the front at the same time and it has leaked oil through the air line since day one.
I like the simplicity of the auto lokka with nothing to go wrong, switches, air lines, compressors, o rings. They also have a uncontional warranty if a rememeber correctly.
With the auto lokka it is one less decision to have to make (lock/unlock) before every obstacle
In the end Its what suits u best

Cheers Matt
