[Gippslander]

I am chasing some information can you fit diff locks to a P38 and if so what breed is preferred i was looking at KAM models but cannot be sure they fit the housing looks like it has to be modified any help would be appreciated.

I have an ARB type in the rear of mine Keithy P38 has An Ashcroft locker in his and posted a great video to show the result

Cheers for the linkage Wayne!

As he mentions, I have an Ashcroft locker in the rear of my P38. You might find that they are out of stock at the moment, but I do highly recommend waiting! It's worth saving a few hundred pennies to get this product. You will need to order a P38 spacer ring when you purchase the locker.

So far I have had mine in for 9 months with no issues. It gets used almost fortnightly and has got me places that land cruisers only dream of!

It can be done DIY, but if it's your first time I would recommend getting someone who knows diffs to guide you as you need to set the pre-load spot on!

Hope this helps!

mmmmmm lockers aaaaaaaaah!!!

[p38oncoils]

Of the airlockers the Ashcroft Air Locker (see link below) would be a preferred choice over the ARB Air Locker due to the Ashcroft Air Locker being a better design in regard to internal air leaks but if you are interested in a fit and forget locker you might want to have a look at the Kaiser Locker in the link below as well.

I suppose this question has been asked (and answered) before, but...

Does anyone make a 'locker' of ANY kind, auto or air/electric/flux-capacitor operated Centre-diff for the BW transfer case ? - To do away with the VC...

Hi Keithy,

glad you are pleased with the locker,

Dave

[Keithy P38]

Very pleased Dave! Not to mention easy DIY instructions that come with it!

When are you going to have more stock? My old man is looking at a pair of them for his new 130!

Hi,

we will have more available in 1 week,

Keith,

Wanted to regurgitate this one. Do you have standard half shafts (10 spline?) with your ashcroft locker? Are there any options for HD shafts?

Did you just tap into your EAS receiver air supply for the solenoid? Our did you go for another compressor?

[Keithy P38]

I thought we had the 24 splines (or thereabouts) in ours? I didn't completely remove my axles when I fitted it so can't remember! Either way my axles are stock standard.

I used the existing on-board air supply for mine. As I have already run a tyre inflation line from the tank to both the front and rear of the Rangie, I simply tapped into the rear line with a t piece (6mm fitting for the air locker feed line), ran it into the fuel flap emergency access area, solenoid lives in there, then ran the line back down through the grommet at the rear along the chassis to the fuel tank, then followed the rear diff breather down to the diff. Plenty of cable ties along the way.

One thing I have not done (but its on the list) is run a pressure regulator before the solenoid. Our tanks hold 150psi and the locker only needs 100psi. I have no leaks and have had no trouble with my locker at 150psi but I would hate for it to blow seals.

To date it has performed flawlessly. Still highly recommended! It is the reason I could tow a classic Rangie up a series of steep hill climbs full of wombat holes yesterday.

Cheers

Hey Keithy,
I've been chewing on this one for a while and am almost sold on Ashcrofts
as I believe they are the best option for the P38 due to their construction.
I think they are also good value. Have you also got front locker?
ps.
Dave just a thought maybe you could include modified P38 manual diff lock switch in your kit this could just pop straight in place of blank switch next to EAS on dash! (Just a suggestion):)

I bought a spare suspension height disable switch (whatever that switch is called) to use for the locker but ended up fitting the ARB style in the small wood trim on the right of the dashboard. If you use a standard switch it needs to NOT be a momentary switch like the other switches are I believe.

Only the rear is locked in mine. Figured that the traction control semi locks the front while retaining steering. Surprised how much of a difference the ashcroft locker made over traction control. I knew it was going to be better when lifting wheels in particular and keeping momentum but traction wise it's helped a decent amount as well.

This is the switch I am referring to!

Didn't realise they existed. I bought the exhibit switch thinking I'd change the pic on it... But that switch would look tidy in my povo pack with no front driving lights. I've lost one spot for the eas power switch and have one spare still.

[FANTOM P38]

If youre really quick its on Ebay now!

[Pete38]

If youre really quick its on Ebay now!

Yeh I found it thanks. I'm on holiday in the UK and have a postal address so the postage is free even... But as I've already put the locker switch in the wood panel and the terminals are unusual I guess, I'm not convinced I'll buy one now.. Would have before if I knew about them though....

Our p38 never came out with a diff lock huh? So guessing they're after market second hand switches.

[Keithy P38]

Yeah only a rear in mine Fantom! As Peter says, I'm of the theory that traction control has lost an axle to override so it can have the front all to itself!

[davidsonsm]

Can I ask if you swapped out your half shafts or stayed with the originals? Also with regards to the air supply, did you just tap on to the air receiver pipe?

[Keithy P38]

Think I may have answered this elsewhere, not sure!

Original shafts, tapped into onboard air.

Cheers

II kept the originals and pretty sure Keith dud the same.

I tapped in in the engine bay where the pressure gauge is for my emergency air kit is near the eas valve block. But as Keith did his differently so I'll let him answer that.

See post #12 in this thread for in depth answer

[uzz32soarer]

I have had twin ARB air lockers in mine for about 8 years now. Never been a problem but got me out of a few!

[Gippslander]

ok i have purchased two lockers and two crown wheel and pinion sets 4.1:1 ratio from Ashcroft they are now fully assembled and installed in rig so far so good, they do make a fair difference in engine revs and best fuel economy is around 14lp/100 kms at present. I have only got 500kms on them so far, i tried to get the air suspension back to original also but gave up too many alarms sorry Paul even after all your help i just thought it was too hard.
So i have installed a full set of Dobinsons with 50mm lift and spacers at 20mm it rides really well and i will live with the shame. I used a remote compressor tapped into the original air receiver and fitted a pressure switch which controls the compressor. Currently the compressor cuts in at 90psi and out at 120psi the lockers are good to go at the push of the button. I will be changing the oil in the lockers next week i initially put 75/90 diff oil in with a tube of Nulon diff and gear lubricant, to help with the initial run in of the components. Test ran for 5kms checked for heat all good did the same at 30 kms and again at 100kms i have spot checked since and all seems good. I will swap to 90/140 and a tube of Nulon in each diff and see how it goes. While i was at it i changed the starter motor as i had the inner guards off allowing replacement of the starter i also changed the starter bolts to normal headed to make replacement easier in future had hell removing old bolts the allen head was rounded and had to revert to cold chisel to get it off. Last few jobs before i leave it alone will be a snorkel i have got an idea to run a pipe inside the mud guard and shape it too the guard internal curvature then fit an external box at the rear of the guard similar to a Discovery 3/4 type see what happens.

Hi

Sorry to hijack the thread but quite a few of us are very interested in this approach, so once you get into it could you please tell us how much room there is under there and if possible post some pics :D

Thanks
