Hi Andrew, you are spot on in that there is no such thing as a free lunch. All lockers ,manual or auto have different problems. My choice is the ARB air locker,you can choose when you want it in or out, also use the comp. to inflate tyres after a bit of off roading or sand work.

Allan replied:

Andrew, I went for the Lockrite in my part-time 4WD 80 Series and have done over 25,000kms without any problems (bearing in mind they only have to operate when the hubs are engaged). I am not aware of any downsides but I have heard they may cause more tyre wear on constant (full time) 4WD's but have never seen any hard evidence. In fact I believe the positive diff lockup with an Air locker would put more strain on the drive train in firm conditions. The Lockrite's certainly are a lot cheaper and simpler. An Air locka might give you the opportunity to turn on only when you need it but its not much use if you are stuck up to the axles before engaging. I'll stick with the Lockrite as it's automatic and works when you need it. It will be interesting to see other comments.

Allan

Andrew,
I am the one who posted the note and I have one for sale.
I have now tried both air locker and lockrite in my GU patrol (front).
THe air locker has like the other guy said the advantage you can turn it on and off.
The lockrite has the advantage that is "proactive", ie: too late if you are stuck up a rut....
The other benefit of the lockrite is that if you are going up a very slippery rutted track and there is a need to turn on a switchback you just turn and the lockrite disengages as you turn (tested).
The air locker will NOT disengage at all and you will have to remember to turn it off and then it may be under load and it may not unlock...
The only one minus I found with the lockright is that on a long dessert trip if you are in 4wd it adds little pressure on the steering (gets heavier as you turn) ona straight line no problems.

Andrew,
In answere to the other question, there seems to be a 40% of people using lockrights, more and more guys are now using them on competitions because they don't have to worry about turning them on/off they are (proactive), I have four friends with GQ'a and GUs who have them and had them for years on the GQ and had no problems.
I am planning to do up a GQ shorty for competition and that is why I went to the air locker on my GU. I am not in a harry to get rid of it but if someone interested comes along I will get rid of it.

Andrew, I have a Lock Right on the front of my part time 80 and I love it! No real draw backs that I have found. As far as heavier steering goes - my lady's falcon has heavier steering. Today I drove a VT Commodore ute (work vehicle) with power steer and I was supprised to find the Commodores' power steering has heavier 'return to centre' than my 80 series when in 4wd. Also, if you turn the air locker off to turn a corner,(assuming front diff here) then you have the equivalent off an open diff, which we all know can end up giving you no wheels driving (front axle). The lock right will *always* have a least one wheel driving and that is the one with the traction. I bought mine before the price rise in June/July. I believe they are over $1000 at TJM. Could be worth buying from the USA. Very easy to fit by a home mechanic, I fitted mine.

Noel replied:

Andrew - Have just fitted a Lock-rite to my Jackaroo T/D and would agree that they are fairly easy to fit, cause slightly heavier steering when turning and much improved traction. Try www.4wdsystems.com.au for prices. Regards, Noel

Is it viable to put a Lokka in a constant 4wd 80 series? Will the center diff compensate for this?
I have heard lots of conflicting reports on this.
Has anyone actually tried it?
Cheers Rob

Will replied:

I once met a guy along a firetrail who was driving a LR discovery (full time 4wd) and he has one on the front, he said he had installed it some years ago and never had any problems

Dion replied:

I have just last week has a Lokka fitted to the front diff in my Rodeo, and with only one weekend away with it, are very happy with it's performance. I were at Dorado Downs - Geranium on a club trip. The Rodeo got a sensible caning within my limitations, and didn't let me down. There were a couple of hills that defeated me, and many others. On those two hills, all the traction in the world won't help you, you need pace. The sand was just too soft. I am really looking forward to trying it out in the mud. Cheers, Dion.
