Wheee!
ARB rear locker going in on Tuesday.
But I was wondering of what value the old rear diff would be.
24 spline, 4 side gears etc.
Is it something someone else could use or should I just keep it as a spare?

Rear Diff P38a - any good to anyone
Moderator: Micka
Hi Rohan,
Made a few little changes - reset EAS ECU to go up another 1" then I put longer airsprings in to overcome the bouncy ride at full height, now want to put in 1" or 2" spacers in to help sort out longer shockies to get some more droop.
32" tyres, imported 4.1 diff ratios from US, on board air, cross linked air springs.
The diff locker and 4.1's go in tomorrow, will try out on weekend.
Rear Locker will not hurt ETC at all (think ABS) but some concern over viscous centre.
Both Maxi Drive and my ex Maxi mechanic don't think it will be a prob...
(Have a spare set of 4.1 R&P here $1700)
So without having tested the 'big' changes the Rangie is currently a dream on and off road. It still amazes me how easily it overcomes sections that I think are tricky.
Originally I did want a 2 door RR for bush bashing but I'm committed part wise to the P38, it's pretty now my weapon of choice.
Once I get the wife a nice car all will be cool.....
Get into it!

I think you will find like Aquarangie off here that when you have a rear locker engaged for the first time offroad you will try to spin one front wheel only - until the viscous centre locks up. Of course the ETC should help minimise that.

Hardy,
what airsprings have you changed to, and how does the cross linking of
the springs work? Any thoughts on longer shocks as opposed to spacers?
Do you disconnect the anti roll bar off road?
Mine is currently on 32" BFG M/Ts, and two true tracs and Maxi Drive rear halfshafts are waiting to go in. Lots of other mods planned, too, but time is the limit. Well, money, too.

Hardy,
Keep in mind with your viscous coupling transfer case that you may find that all your drive will direct to the front on occasions. I'm not sure, but the viscous coupling in the 38A's may be better than the ones fitted to the classics (could be the same box, dunno!!!).
Buty as Isuzurover has commented, your etc may help quite a bit here.
Good luck, hope to see you out on one of my trips soon (if it doesn't bloody rain!!!)

Yeah - bugger trying to test the viscous centre under locker - I just need to work on going on a trip first.
Bloody extended family this, special friggin occasion that, stoopid rain clounds keeping us pansies at home when the calendar is finally free.....
Wilsby - I put some 40mm longer airsprings in rear, then moved old rears (with new rear pistons) to front. This sorted out the stretch factor under re-programmed max height setting. Rides comfy at that height now but I only use it when needed - not much droop left otherwise.
Rick ('s 4WD in Nerang) gave me the wonky eye over the 40mm bags though. Apparently aftermarket maunfacturers make them longer initially to overcome eventual distortion under normal operating conditions. He didn't say exactly that but I got the gist of his "LR mech crypto jibe" I check them every second day anyway so if there's a problem I'll find it first. Bags are Dunlop, I can supply for $175 ea inc.
The cross linking is simple solenoid affair that opens airline between left and right. The theory is that the side under compression offers no resistance, expelling air over to other side, forcing it down. I haven't really worked out a way to test it though - need controlled environment to run the comparisons. ARB might let me use their mechanical "tricky trap track" Don't have detatchable swaybar - that was the idea of the cross linking - will see how it goes.
The benefit of 2" spacers is two-fold.
1. Basic overall height increase, to centralise airsprings to an optimal median for re-jigged 'standard height' and giving more droop at higher ride height, all at the expense of soon to be redundant 'access mode'
2. Allow for fitment of longer shockies! No room to go higher at rear, don't want really to rebuild front shock towers either. Without dropping axles down, it's really hard to find the right shock specs. OEM fronts may be perfect for rear once spacers go in.
I am still searching for some even longer springs though - the proper solution.
Yes - even when I finally sort the money side out, often I'm too buggered from earning it to do the fiddly thinking tinkering thing - especially when there's no incentive because NO TRIP TRAVERS is in charge!! Sorry Trav, not having a go. Just having a dirt/petrol withdrawal episode.
What's your rig Wilsby - old shape or old new shape? Not new new shape?

Trav - I don't know whether yours and mine had same actual viscous centre (originally) but I do know that our diff centres are on different sides of each axle. So the transfer cases would have to be different and if so it's quite likely most of the internals would be differant too. No simple change over to manual centre diff transfer case then....
But I don't know a lot about this sort of thing - it's just speculation on my part.
But I'm real keen to see what happens once locker is engaged.
Here's a question - Disco II uses same hubs as P38a - the wheels are interchangeable. Does this mean they use same axles? Are their diff centres on same side as P38a?

Hardy,
mine is old new, just like yours. '96 4.6 HSE. I have some rubbing att full
stuff both front and rear. I have been contemplating a mild body lift, but
that would not leave room for taller shocks. Spacers or taller air springs may be the answer after all.
If you have two 18 mm spanners, you can remove one of the links to the front sway bar in less time than it takes to pull the pins in a detachable sway bar setup. Unscrew both ends (up and down) and remove it, or it will catch.
Do you do the cross linking in front or rear, or both? And what does the EAS brain think of it?

Going out to Balck Duck on Sunday. I'm sure I can find some challenging stuff for you if you wish to go.
Not having much luck with the rain though./ Had 3 trips cancelled inside 6 months due to this (Crystalvale, Nerang the first time and Beerburrunm).
With the dry seaon on full alert, this shoudn't be too much of a problem.

Crikey - this is one multi function topic!
Trav - got a bucks party on this weekend, down m'uncles property behind Mt Warning. Actually I should suss it out for a future RRCQ trip.
Thanks for the invite, but regrettably I decline.
Wilsby - Yes, cross link on both axles. The rear probably doesn't need it, but all airlines terminate at valve block, so I did it anyway.
Not good having both open at once though. The car can flop over to one side.
EAS - I haven't had a problem yet, but only open links whle moving. But once I was stationary with both ends open, car had already flopped over from an obstacle I tested. As soon as I closed both ends the car leveled out. The reality is the EAS may just think the car's on a bit of an angle and not try to do anything until igniton is switched off or put in neutral, hand brake on, foot brake off.
