Australian made "LOKKA" Diff Lock

There is lots about these and comparisons with other lockers in the forum archives. I have them in the front on a 60 series LC. Very happy. Get them installed by someone who knows what they are about. Dont use them on full time 4WD. No difference in the steering when not in 4wd. A slight change in the self centring feel when in 4wd. Nothing you wont adjust to quite quickly. Most users think they are better on front than rear. Great for dune driving or situations where you might want them turning on and off repeatedly.

I agree with what Mfewster said. I have one in the front of my car (part time 4wd) and I will keep using them as long as I have 4bs.

I installed it because I got sick of the car loosing the use of the front axle everytime it lifted a front wheel off the ground in a difficult situation. If the rear axle could keep the car going then it was not a problem. If it couldn't then you would sit there with both rear wheels spinning plus the lifted front one and the car going nowhere.

These diffs always have at least one wheel driving and that makes a huge difference. It is not mechanically possible to have no wheels driving.

I installed it myself but I have had previous diff experience. It is not hard to do but if you choose to go that way, I would recommend you get a workshop manual in addition to the instructions supplied with the lokka. The installation instructions could easily leave a lot of unanswered questions for the inexperienced.

The archives have a lot of info on them as has already been pointed out, This recent lengthy disussion on the link below is also well worth reading.

Have had one in my Patrol now for 170k without problems.
Yes it is in the front axle and the steering is slightly altered when 4wd is engaged but you will soon get used to it.
I have had a front locker in my last 2 4wd vehicles and would not be without one.
Beats electronic traction aids hands down.

I had one of these in my part-time kitted 80 series, and recommend them also. The steering was of course heavier and wanted to return to centre all the time in 4wd, but the benefit of extra traction made it worthwhile! Like others have mentioned get it installed by someone with diff experience if you can. Sometimes l found it would not unlock if l was pointed downhill and trying to turn, but a quick stab of the accelerator soon sorted it out!
If you have a part-time 4wd with free-wheeling hubs l would recommend one of these mechanical lockers.

Me too. Front diff. Makes big difference. Same as above about steering. Had mine in Hilux for about 60000km

had one in my 100 series part time 4x4 for a while now

great extra traction and easy to fit - just be carefull and measure clearance

biggest pain was re fitting crownwheel

good luck

Can't fault mine, no downsides on the Jackaroo fitted to the front...can't even hear the damned thing although I know it definitely works.

Im with all the above. Mine are in the front and worth their weight in Gold. No troubles but always I take it easy in the hard stuff.

You would have to be experienced to fit them to the more modern cars, get someone to fit them because you may need machining or more shims.

I would also recommend to add Manual Locking hubs if you have not already got them. Cheers tony
