Hi everyone,
I am considering fitting an air locker to my HJ60 Landcruiser.
Just wondering whether I should fit it to the front or rear diff.
The vehicle has no other mods except 31x10.5 tyres.
Also considering fitting it myself after I replaced bearings in the rear diff
six months ago without too much trouble. Any pitfalls to avoid?
Any other thoughts would be appreciated.
Thanks

G'day Moz,
My advice would be that if you have a really good LSD in the rear diff (which is unlikely to be the case) then the locker should go in the front. However, it is likely the rear LSD is stuffed (if it had one), so the locker should go in the back.
As for the idea of fitting it yourself, I wouldn't do my own (I got ARB to do for me).
Just my opinion.
Good luck

I have run a front air locker in my past 3 4X4's with varying LSD & open rear diffs.
I would go again in the front as a driving wheel is easier to get up an obsticle than a rear one pushing it.

Im with Les I would put it in the front, and if you are confident, have a go yourself, I would .

I'm inclined to put in the front and get a rear LSD working,
but a mate of
mine reckons you lose a lot of steering control in
with a front locker.
But I suppose with an ARB unit you only select it when needed.

About the same price to rebuild the LSD as put another locker in the back I am told as I was thinking along the same lines !

I asked this of a bloke in club who works for large 4wd company...
The first answer was in relation to removing LSD, and having an open diff for rest of the yr....
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
No open diff doesnt give any probs as long as youve got a bit of down travel left on shocks and susp not too stiff.
Rear a bit safer for novice drivers plus a tad less strain on CVs if wheel spinning not that you do that.
Front not so forgiving when you're under stress.
Traction improvement going up gnarly bits very good esp when in conjunction with Working Nissan LSD.
I fitted Front 1st to my Patrol and it made a world of difference.
You will notice improvements from the rear too about 80%.
What would I recommend,
Heads rear.... Tails front..
PS. If your not sure and want an easy aid fit Rear.

Fitting air lockers is pretty specialised. I wouldn't touch it unless you have plenty of mechanical experience. Setting up a diff isn't as simple as tightening a few bolts. Do it wrong and you increase wear on the diff significantly. Not worth the saving IMHO.

Fit to the rear first, as more traction is gained from the rear wheels when climbing.
As for fitting, pull the diff out and take it to a ARB supplier, get them to fit up the Diff Lock and you re enstall it. You will need todrill and tap diff housing to fit the air line - parts supplied. This will save you a lot of dollars and you can re pack the rear wheel bearings while the diff is out.

I can't agree more then with
Well 55.
My pinion bearings went on the rear diff and while i had the diff out i fitted the air locker. You won't beleave the differance it makes. I'd definatly go the rear if i had to do it again.
As to doing it yourself, take it out and hand over to a diff specialist to set up.
If you have access to a press for the bearings and the correct size tap you could do all the hard work and just get the back lash and pre-loads set for you. This is the way I went. The instuctions are really easy to follow. Good luck with which ever way you decide.
Cheers Nino.

Thanks for everyone's input.
It seems to be an issue that needs a bit more research and
has a fair dose of personal preference.
I'll look into the LSD side of things and when the locker
comes I'll probably send the centre off to get set up.
Thanks,
Moz
