Hi S/G
I had one in the front of my 80 and loved it. It did tighten up the steering marginal, cornering not a problem as it lets go if you back off slightly or if you keep power on it can stay in with no problems. In 4wd hardly a noise, but in H2 with front hubs locked in it did click turning the wheel just un locking with no load. Only wish I did the back at the same time.

I had one in the rear of my diesel Jeep Grand and while it was great off road, the Mercedes auto transmission couldn't handle the characteristics on road and would throw the engine into limp mode at some roundabouts. I have since found out it is a common thing with that auto. The petrol Jeeps with US autos don't have a problem. I don't know about other brands. The clickety click noise on corners when they are in the rear can be annoying.

I have had one in the front for eight years and 103,000 ks and would do it again anytime.

You will notice a slight difference in the steering but it is not worth worrying about. The car has never tried to drive on straight ahead like they can with manual lockers.

There is a lot of incorrect information about them on the net. The most common claim is they unlock while going around corners and that could leave you with an unlocked diff when you might suddenly needed it locked. The truth is they are unlocked, or in the process of unlocking, just about all the time. That is why you can put one in the rear and drive around a city all day. You can't do that with a manual locker.

They work by using engine applied torque to drive the wheel with the shortest distance to travel while the one with the longest distance to travel i.e around corners or up and over rocks etc, can roll ahead driven by road applied torque.

The moment a wheel looses traction, they will lock instantly. As soon as it regains traction, and that could be less than a metre further along the track, the unlocking process will start again providing one wheel has a longer distance to travel.

When you look at a typical bush track, or even a sealed road, the wheels are just about always turning at different speeds. The diff is rarely fully locked and that is why you get a slightly heavier feel through the steering, not the very heavy feel that you get with the diff permanently locked.

I think you should read this...

How a Lokka works

Straight from the manufacturer, they are locked all the time and unlock when there is a torque differential on a firm surface where both wheels have traction. If I put my foot down going around a corner on tar, it would stop the lokka from unlocking and the inside wheel would burn rubber.

Another fan here. Front of a hilux for me. Best improvement for the money that you can buy.
I will say that mine was an sr5 hilux with the electronic diff disconnect so when the Lokka was installed it dragged the driveshaft as well which pressurised the front seal in the tranny case and made it leak twice. This was remedied by installing a couple of hubs off a Povo pack hilux. This issue was endemic to only sr5 hiluxes up to 2004. Shouldn't affect other vehicles as the ADD only disconnected one driveshaft from the diff - strange setup.

Had one in the front of a GQ was great in most cases. Created under steer on muddy corner though. Have since had air lockers without any issues. I prefer the selectable lockers myself.

I had the Lockrite (Richmond Gear), same thing. Best mod you can do to your 4By for the money.

Different to drive at first but your subconscious soon learns to the point you may think the locker (unlocker) has stopped working.

Highly recommend.

Had one fitted in the front of my 2000 Courier diesel ute over 160,000 km ago and its great around the muddy steep farm paddocks, across the deserts, Fraser, makes it a much more capable vehicle and absolutely no problems.
