Lokka

I had one in front of my 2.8D Hilux , great thing , I have since had Air Lockers in my D4D Hilux , now have ELockers in my Dmax .

If I could of got a Lokka for the front of either of those vehicles , I would of no question
They just work don't even have to think about it .

Because your LC has free wheel hubs , just unlock the hubs , everything is normal on the road .

Even so I could drive my Hilux on the highway with the hubs locked , without issue , I could feel the Lokka working on roundabouts , tight turns ect but was never a problem .

I did 200k in my 2.8Lux ,a lot of Highcountry 4x4ing , the Lokka never gave any problems, not one can't say the same about the bloody Air Lockers , very early days for the Elockers , so far so good .

I fitted a "Lock Right" ("lokka" I think is the cheaper copy) to my 80 series and it was faultless and fantastic for 17 years and 250000kms. It was a part time front diff like yours but they work really well. You have to remember they are an automatic UNLOCKER so you don't have to remember to unlock immediately. However, you will still get wind up on hard ground.
Spend a little extra and get the best of that style. I will be putting one in my 76 series soon.

Hi Trawe
I had one in the front of my 80 Series [Auto Lokka] and loved it. Crossing the Simpson you could feel the front pulling, but I wish I had put there rear replacement one in to, as the Tojo LSD is useless. With the front hubs in it did make a clicking noise when turning the wheel nothing to bad though in 2H, in 4H no noise. In 2H with hubs out no noise. For the money you can not go wrong and it cost me $350 to get it fitted or you can do it your self with there full instructions supplied. If they did one for the front of a Ranger I would get another.

I had airlockers on my Coaster 4x4. They are full-time locked when engaged...

"Fantastic" is the only word I could use to describe them...

some proviso's from the learning experience,,,
Full lock turns tend to push you forward
Angled ascents can drag the front down
Straight ascents can create landslides - all the fun stuff

I had one in the rear of my Jeep and had to remove it because it upset the gearbox/abs sensor electronics. It kept going into limp mode on roundabouts. I reckon it will depend on the car but no matter what, the driving dynamic will change unless you have free wheeling hubs. Some find the clicking nose it makes when unlocking around corners a little irritating. I did find an interesting effect, one of my rear tyres started going flat and the rear of the car was trying to turn a corner on its own. It's essentially a solid axle that unlocks if the force differential between wheels is great enough to pull the cogs apart. Excellent off road, never had a problem there as the wheels couldn't grip hard enough on dirt to unlock it.
