Outer Limits 4x4 Board

I keep braking diffs.. I need some advice on a stronger
soulution. The car Is a 98 v8 disco on 35's. Cheers

are they completely stock?

are they being set up correctly?

are your housings true and straight?

Arb, Jac Mac and soon maxi dirve are all good rover type replacements. Jac mac offer a hypoid bolt in that is stronger again, or you can do your own conversion with toyota hi lux diffs into the rover axle case

Serg

I'm pretty sure they are both stock. I replaced
there rear bout a month ago the blew the front
last night. I was goin to replace em both with arb
but I've been told I'll still have problems. Do u
know rough prices on the hi lux conversion and the
jac mac ones and are the jac macs lockers?

Hilux conversion is the go, front high pinion from an 80 or 100 cruiser, rear from Hiace to match 4.11 ratio, then Jack mac axles

Diffs can be upto 500ish each, but can also be had for bargain prices

axles will be around $650 for front, $800 for rears, good time to stick lux cv's in, and hope you know someone with a lathe

ok cool so is it a difficult connversion. are arb air lockers not strong enough?

i dont know much about the Toy conversion so ill leave it to the guys that have done it.

Arb's are good as are Jac Mac and Maxidrive

the difference between Rover diff and hilux is the rover is spiral bevel design and the hilux is hypoid. While the spiral bevel is more effiecent at transmitting power, the hypoid is stronger by design due to the location (offset off center) of the pinon, thus it can be made bigger and have more engagement with the ring gear.

no matter what you run, axle case trueness and diff set up are critical to longevity

Serg

PS not sure what ratios the toy hilux are???

What actually is breaking?

If its just the hemisphere that the crownwheel bolts to then a locker is a lot stronger than standard. If its the crownwheel and pinion then look at something thats not Rover.

Hilux diffs are the way to go, as you get a stronger rear and decent ratios, can be had in 4.1, 4.3 or 4.55 I believe from bundera's

You can fit locker to rover centres, but you still need axles and diff gears do have a decent set up, only prob with the lux conversion, is you have to do it all at once, so if you got no coin, makes it hard

Its an easy conversion, I've done quite a few now, none return as opposed to rover centres

for pricing on your axles and c.v's email keithh from rover tracks (across the pond in the u s of a), his gear is supposed to be good for up to 37's. then as said a 100 series front and hilux rear, and your choice of lockers.

that wont fix the diff problem unless he goes the toy route, in which case he could use jac mac as well. Keith does bloody good stuff though.

if he stays with rover type diff (arb, maxi or jmac) id vote for Hi-tough engineering axles from the GC

Serg

Get a 101 then you don't have any of these problems - they have the landie running gear that all landies should have had.

sorry serg, mate thats what i mean't in reply to cloughys post re the toy route

cool cool,

does the hi pinion have any clearence issues with the steering arms or other parts?

this is still a good option if u wont go past 35's and don't flog and bounce the farker out of your truck, i ran stock rover 3.54's, arb's, with jacmac axles and haultech modded hilux c.v's for 3 to 4 years on 35's and no breaky bits, and know plenty of blokes that have the full maxi kit on 35's and no snappys for years and years, although they aren't hard on their trucks, depends on your driving style

nup, improves my front shaft angle too.

Patrol front diff is high pinion also - won't break that in a hurry

was thinking that would be another advantage

have you seen the new sixty9 housing on pirate? could be a good housing to upgade the sals to dana 6o internales etc....

while there are definitly some stronger aspects to the nissan stuff, there are also areas that arent better than a hilux.....plus the whole housing suspension offset issues to deal with

just so the OP knows, you cant fit any nissan diff in a rover housing

but ashcroft are squeezing a ford nine in

BUT with Nissan diff swaps, the brakes are farking fantastic

yep the Force9 is what ashcroft is doing, a custom 3rd housing to fit the ford 9 inch R+P into the rover housing, its a full set uo with knuckles instead of swivels etc, i believe it will be hub to hub. looks promissing.

Im sure keith @ Rovertracks does something similar?

the Sixty9 is a new concept for the dana 60. basicly it is a new housing with a removable 3rd, so unlike the 60/sals where you take the diff cover off and spread the diff to remove the R+P etc you can unbolt like a rover or toy.....plus its improved in alot of areas and the housing if all steel not cast. the 3rd is cast

a custom 9 front and sixty9 rear would be a good cool set up in a comp def

Sounds like the only thing left of the Dana60 is the axle tubes.

not even,

the housing is a complete new fabbed one, it utilizes d60 gears and diff etc, you can use your own spidles etc....

Thanks for this Serg, they look awesome!

Ok cool. Think I'll go an arb air locker
and save up for axles. Cheers for your help.

if money is tight, put a detroit locker in the rear. Just as strong as a air locker and can be had for around $600 from the states. Then you can afford the axles at the same time.

I hear of these shattering when an axle breaks. I've never heard of an ARB doing that.

ARBs have had failures too. The lock rings have been known to strip under high load. Its common enough for a US company to have started making upgraded lock rings.

for all ARB lockers???

i know the ford9 has some problems, but it has very little engagement depth.
