Will a Disco Series 2 diff fit my 91 Rangie??
I know it's a 24 spline and mines a 10 but will the ratios be the same as I'm looking at converting if I can get the gear cheap enough.

What part of the diff we talkin the center will fit your rangie housing tho the axles wont and the compleet d2 housing wont fit either u can use the d2 center but there no stronger than the 10 spline center the center pin in the hemisphere is the weak point and its the same on all std rover diffs ...

As for ratio it will be the same your cheapest option is find an old 10 spline ARB locker and fit that as the 10 spline axles are stronger than the 24,s and i have the test results to prove that one

Ok i fukedd up its the front 10 splines that are stronger not the rears so dissregard this comment bout the 10 spliners being tougher

Lokka, you are mistaken, you can fit the whole diff assy,

many people think the D2 have P38 diffs, they don't,

10 spline axles stronger than 24 spline, dats some crazy shate your talkin

I am talking about the centers as I'm looking at getting a couple of centers and getting lockers put in them (as to what ones I'm not sure YET) then get hardened axles for them and then do a swap over so I can keep the car on the road while I get the lockers sorted. And yes at the same time convert to 24 spline.

Fitting a whole diff assy from disc to disc from a d2 to a d1 or RRC it wont happen unless ya change the rear trailing arms and fitt a watts link from the d2 or weld on the mounting brackets from the RRC diff housing to the D2 housing tho like in my first post the centers will fit in either diff

10 spline axles stronger than 24 spline, dats some crazy shate your talkin

Thought it was crazy too when i seen it on AULRO in a post there was a link to a u tube vid were they were testing cv's and axles and the ashcroft was the strongest then the std 10 spliner then the 24 spliner

ok then.......................

do u have a link to this thread on AULRO?
maybe some info, what axles exactly were in this test?

where they brand new oem 10 and 24? and how many did they break?

unless it was about 50 or more of each do you think its a fair indicator of the truth?

btw go look in the rover bible here, hsv rangie added a post i typed out from a maxidrive info sheet, which has all the rover axle info and specs including torque capacity of hytuff axles, which are based on stock rover spline sizes......

smaller = stronger???? how?

I think you are talking about changing the whole axle, I am talking about changing the diff assembly,

you can interchange the diff assembly and you can interchange the diff centres, not the whole axle,

Yep thats the stuff i saw on AULRO a while back i had a look for it and couldent find it and the data on the front shows the 10spliner being stronger than the 24 spliner tho in the rear (which i never seen before now ) the 10 spliner is weaker than the 24 spliner thanks to MRashtrans for the info and mate we must have had a mix upabout the d2 stuff with you calling a diff assembly what i know as a diff center ah well we shyte happens but the truth is there bout the 10 splin front shaft being stronger than the 24

so Dave you consistanly broke 24/23 spline axles over 10/23?

where these brand new oem?

how many of each did you brake? where they the same side ie: both long or both short?

cheers, serg

hey again, probably getting sick of me now

Dave i looked at your front test.....you tested 10/32 and 24/32......
these both share the smallest root dia of 24.1mm for the 32 spline????

my guess is that because the 10 spline is closer in size to the 32 its more uniform and will twist more like a torsion bar.....and the bigger difference in the 24/32 spline axle make it brake sooner

i think when most people say 24 spline is stronger than 10 they are referring to 24/23 over 10/23 0r 10/32

have u tested 10/23 v 10/32 v 24/23 fronts same side???

serg

Okay then I have another one for you all.
What about a mid 70's rear diff complete assembly from disc to disc as I can get one with a Maxi Lokka and axles ??
Will it fit my 92 ??
And what about the CV's I've heard somewhere about the earlier CV's being stronger??

no such thing as a factory 24/23.

Actually there is. AFAIK - Aust military 6x6s have 24spl rover diffs and 2522 CVs. Also, armored 110s had salisbury front ends with 24/23 inner axles and 2522 CVs.

Not exactly common though... And there is no comparable 10/23 to compare against.

ok so stock COMMON axles are 10/32 or 24/32...????

so what were range rover fronts in a r60665?

so if 10s are broke higher in test, but most people have broken them in there vehicles more than 24's is it just cause the 10's will have seen more kms???

serg

While the 10spl and 24spl weren't much different in a single twist off, I'd expect the 24 spline to handle fatigue better.

The design of the 24spline end having more teeth, a bigger core and smoother transition into the splines makes me thing that it's a more durable axle.

I'm in the process of swapping my rangie 10spline stuff for 24 so I've got the different pieces side by side. It's cleaning all the oil and crap off them that's taking all the time.

It is the stock later model 24 spline axles that are crap and Dave's test proves it. Obviously poor quality materials.

Dave have you broken an genuine "HD" 24 spline shaft from the "23S" axles? I'd be uinterested in how it rates. There has been discussion over whether they are better than those later model 24 spline shafts. Nobody seems to recall one breaking.

Yeah sorry, I was talking about the rear 24v10 spline, I hadn't seen that front breakage chart but I do note the torque to break is similar despite the 24 splines breaking sooner (less twist).

In the fronts, what do you mean by "later model"? Were there earlier 24 spline which were better?

ok so were all common rover 24 spline axles 32 spline at the cv or other????

defender, disc and range rover?????

serg

For front diff, 24 spline on happened with the "later" style axles when the 300TDI came out and these all have 32 spline at the CV, other than the rare ones Ben mentions.

I'm talking about rears. There were no 24 spline fronts before the 1994 axle introduction. When I say "later" I mean the standardized axles that started with the 300TDI introduction.

These rear 24 spline axles seem to be very weak. That is what Dave's test showed. They are no stronger than a 10 spline axle which means they are made from cheese......

Prior to these "later" axles, 24 spline rears came in Salisbury axles and Rover style "HD" axles. These "HD" axles have 4 pinion centers and 24 spline spline axles. These seem to be much stronger than the "later" model 24 spline axles based on the fact that I can't find anyone that has broken them. However, they are not particularly common, so it would be nice to see a breakage test.

You boyz down south would not know of these as you never got 90s..... Around here, they are quite common as most MOD 90s had them fitted.
