Hi guys,
Thanks for comments in my previous topic.
Could you please advice: I have original 100% locker from Toyota Corporation installed in front axle, I would like to install it in rear axle and in front – Lokka. Actually I don’t need all the time locked diff (rear), but most of all I use my vehicle not in town (Sands, muddy roads rare swamps). Vehicle is Toyota Land Cruiser 60; front
suspension (springs, front
bridge track rods and Panhard rod) will be installed from Toyota Land Cruiser 80.

I would probably put the Toyota locker in the rear and drive normally with it unlocked(obviously) and the Lokka in the front which will only be working when hubs are locked and 4wd selected.
That way on the road all in normal but you can introduce the lockers as needed.
We have an 80 series DX with the average LSD in the rear and a Lock Right in the front. Works very
well and would only be better with a Locker in the rear.
Just my thoughts anyway. Cheers

As I recall, the manufacturers/distributors strongly recommend that they go in the front. Ours, LC60, therefore went in the front and works just fine there. Had ours for quite afew years now. Seem to remember when I researched this, before making the decision, some stories of the locking/unlockingin the rear happening while cornering at speed on slippery bitumen and leading to less than happy driving. Scratching the memory banks, but as I recall. in these conditions it can make the back jump sideways.

Hmm seems the crowd is @ 60/40 for lokka's in the rear.
I would put them in the front. When I got
mine for my Hilux Extra cab I was told by many companies that they reccomend front because,
- Increased tyre wear in the rear, as above they are really unlockers so yes they do unlock but if you are driving straight they are locked, now unless you can drive exactly straight and not move around your lane a bit then you will iincrease tyre wear. Similarly for slight long corners unless it is enough force to unlokk them then you're lokked.
- In wet conditions they can suddenly lokk on when going around a corner and you may lose control. They are NOT LSD so once they lokk you r going from nothing to full lokk. Case in point customer just b4 me insisted on rear Lokka's against fitters advice and lost control, ended up with fr/l damage and in the road drain going up Rex's
lookout Cairns ->
Port Douglas.
- By disengaging fr.hubs you can turn them off.
For the above reasons I would look for a LSD in the rear.
As it is in our Hilux, it made such a huge difference that's all we needed (fr Lokka) and just have the original wornout LSD in the rear.
YMMV as I don't have them fitted in the rear but that was the advice from many dealers in many states when I was researching it back in 2004.
Regards,
Sam.

The Lokka, Detroit Trutrac, etc are all forms of LSD.
Just that these are mechanical LSD rather then clutch type and lock 100% when required.
Difference in tyre wear is marginal and only an issue if driven mostly on hard surfaces, and the slight movement in a lane would have little or no effect. It's going round sharp corners in town and tight roundabouts where you will notice any extra tyre wear.
Lose of control is more likely to be going to fast for the conditions anyway.
four by four is not looking at LSD looking at using a Lokka and a locker.
Cheers
Ross

I don’t advise you LSD if only it would be torque sensitive.
I had speed sensitive – with the help of friction mechanism and LSD oil axle will be locked.
During 6 years I had front and rear axles equipped with LSD, I’m not satisfied. In serious mud only 2 wheels we engaged. But when stating or on slippery surface 4 wheels could carry on.

My advice would be to put the Auto Lokka in the front diff and the air locker in the rear diff as you have a part time 4wd system.
This gives a normal open operation when on the black top and in 2 wheel drive.
When traveling off road or over corrugations when the manual hubs are activated the vehicle has the advantage of a locked front diff when in a very loose gravelly situation then when in a difficult climb or a very boggy /slippery situation the rear diff can be locked giving maximum tractive effort.
I have had an auto lockrite in the front diff of My Nissan for 180k without problems however they do make a clicking noise when the front axle is active and on full lock. The Nissan's rear slippery is still working ok after 200k believe it or not.
The only thing that has stopped My nissan is ground clearance even with a 2" lift.
Just My thoughts and experience.
