Good conversion

hey Matt, can you give me a quick run down on how this works.

is the Hilux centre a straight fit to the rover housing, just requiring new axles or is it the CWP thats a match, how much jigging to be done to get it to fit???

cheers mate

I thought you would have broken an axle by now, i've never broken a diff in my disco (10spline) but have broken an axle and twisted 2 others, after i fitted an ARB rear locker and high tuff axles i don't have to worry

At first i was just going to carry spare axles around and change them when i broke them, but that is a bloody pain when out bush so i just bit the bullet and bought some HD axles

The disco 10 spline axles are the same apart from the flangers, the rangie flangers are rounder and have smaller drive flange bolt holes.

CHEERS TIM.

The centre fits right in, you need to redrill holes for the studs to locate the centre and fill a small section on the housing. You then need custom axles and flanges for the rear, the front you use hilux CV's and have bushs machined for the stubs and either 2 custom axles/ flanges or 1 LC 60 LH axle and a custom one for the RH and new flanges. Best to use an LC80 high pinion centre for the front to clear the track rod. no jigging required, just install the axles and line up before drilling the holes for the studs.

What he said

Its a great way to go about it, as you get better ratio's, and strong axles on open diffs, for less than new axles and diff gears for the rover stuff, then add lockers at your ready

I still find it amazing that you have gone through 3... I had a 85 RRC with 10spline axels (everything stock) and never busted anything, running 33" BFG's.

Now with disco I have the 24splines, I dont drive it as aggressively as the RRC but still cant see why yours are going.

Some drive harder than others Stooge

Also, the current ARB lockers have a degree of commonality through their range. You can swap the locker side gears to use Rover axles instead of custom Toyota pattern axles if ease of getting parts is important to you.

FWIW Just fit ARB Airlockers and Hy-Tuff axles and you should not have any further problems. The diffs you have broken were probably on their last legs anyway. The Toyo diffs have their weaknesses too. Just ask 100 series owners who have tried to back up in heavy going - front diff failure is very likely. The Rover 3.54 CWPs are wuite strong and stand up tp considerable abuse. At the end of the day you get what you pay for - in my experience trying to do things on the cheap always causes more problems, and further expanse than doing things properly the firs time. I speak form 28 years of Land Rover owning experience - and yes I do use my vehicles in very difficult conditions.

But have you ever done this conversion?

Fitting lockers and axles doesn't overcome diff ratio's for those who want to run large tyres, if your never going to go larger than a 32" tyre, Then just lockers and axles are fine
