Outer Limits 4x4 Board

G'day all,

is it worth converting to 24 spline disco axles? I would eventually go to maxi drive axles, but considering changing to the disco axles now that I'm running 255/85 R16 tyres.

considerign running a locker too...but SHHH

will the disco inner axles fit my 84 RR?

I've been on these for about 2 years with a combo of 255/85-16 Cooper ST, STT and Simex 33x10.5 JT2's and they have been good. A mate in Vic with a lead foot runs the stockers with 32x9.5 Simex ET's and they have been good. A guy in the states snapped 2 axles crawling with 32's and a locker. I think they are ok, but it will depend on what you do with them DAS. Another mate with 33x13.5" Claws blew his factory diff before the axles gave in.

Don't know about the fit though.

Well, you don't want the Disco 24 spline inner axles as they have the tiny 32 spline CV end.

I was affraid the front axles wouldn't fit the older RR CV's....oh well

slunnie, are you running a locker??

the 24 splines don't last long in the front with a locker, but mine lasted quite well in the rear with a locker.
but if you are getting a locker - or simply having the hassle of changing from 10 to 24 spline diffs then think about going the whole hog at once. It's cheaper than doing it one step at a time if you get locker/axles/R&P at one hit and the diff won't be in and out like a yoyo.

There are two problems with the 24 spline axle upgrade to your 84. First, the side gears in your diff will need to be changed to suit the 24 spline. Ifr you cvan pick up a cheap centre with a shtredded crown wheel and pinion, you may be able to poach the hemisphere from the busted diff and put it in your Rangie, ot better yet and easier is to get an entire center from a later S1 Disco and axles as a package.

Secondly your flange is totalllyu diffrent. The hubs will also need changing as the earliwer flange is a 'mushroom' type flange wheras the later Disco is a flater style flange (the later 10 splines like on my 92 Rangie are also the flat type, which makes getting axles a pain in the arse as I found out several months ago!!).

If you still are keen to upgrade, it would be easier and less mucking around to pick up a complete 24 spline rear end off a Disco wreck. The fitment is straight forward with a few diffrences here and there.

For all the effot, it may be better to go a Maxi-Drive locker. It may cost more initally, but you fix your strength problems pertty much in one hit.

Jusdt a few thoughts on the matter.

G'day,

Okay I was planning on fitting ARB locker, but don't want crap 10 spline, so thought I could go to 24 spline, and use disco axles for now. and go to maxi's later

But by the looks of it I have to get maxi's axles anyway....both front and rear for 24 spline with lockers.

PS I have the 4.1's already fitted

Ay DAS, no lockers, just ETC.

DAS - what sort of tyres do you have?


I'm doing the 33" thing too - 255/85 is the go for the slim folds of the svelt Rangie, but I just can't make up my mind on which tyre to go with.

Bloody hard finding some 2nd hand, resolved to going brand new.
But not much choice in this size new either!
I have Coopers ST at the mo, and think they're pretty good.
BFG MT sound fine, just worried about on-road handling/noise.

What you got and are you happy?

Thanks,
Hardy

G'day mate

running BFG's new style, noise isn't a problem for me, but I guess they are louder than the All terraisn that came off.

I would love a set of MTR's but they don't come in that size, so next best is the BFG's

The BFG Mud Terrains are fine on the road as a daily driver. Like any mudder they have less braking in the wet, but a lot better than I expected. I ended up getting rid of my All Terrains and sticking with the MTs. Just pump them up to about 35 to keep the mileage up.
