Thread: Ashcroft ATB/Torsen Diff Front, Centre & Rear Install

Coolness... funny I spent a night of self abuse in the Ashcroft site last night lol.
Crown wheel and pinions is a strange new fetish lol, diff pegging kit for front ash locker is somthing I'm thinking of although I realy need to upgrade the axle cv setup first( stock abs cv's) makes you very thoughtfull about what you do when u flick those switches..... rears a sals with a Detroit and hightoughs so I just ignore it ...
Those blue boxes make u smile in a sad ren and stimpy way
Enjoy

Beery,
I love all that internal bling!
Hopefully you will be more speedy than me
I have had a LT230 ATB for my 130 sitting on the shed floor since I brought the truck home. Just trying to find the right time to yank the box - and figuring that the longer I wait the more probable it is that I will want to sleeve the intermediate shaft.
I have no leaks yet but a mates 110 at just a few more kays than mine is weeping at the shaft.

So I think that when I pull the case I will mod the case as per protocol


Anyways - good luck on finding a good fitter. My suggestion would be:

*For the T-Case I would lean towards a landy workshop who has worked on LT230 before - the change to ATB is pie but its nice to have a shop know what it is doing with sleeving the intermediate shaft and has done the mod to the output.
*For the diffs any reputable diff or speed shop would be a good bet for setting the diffs
You will save money if you take the front and rear diffs and the ATB/ bearings and seals into the diff/speed shop and say here fit these!

That my March 2017 bonus money plan.plus rear axles and 4 * flanges, should round it out nicely.
42 kg air freight or sea freight?

Hi beery if you want to take a trip to the coast near port macquarie you could give glenn a ring at momentum 4x4 i know he has done the atb & out put shaft up grade they also fit lots of lockers give them a call on 02 65853200
They will be only to happy to help you out

What's the big upside on the Ashcroft cdl centre upgrade?
I understand the snow and fast mud unlocked side but is that all there is to it?

On my previous 300tdi I found several benefits on fast dirt, biggest improvement was no shunting of power front to rear as you applied power (especially cornering or undulating terrain) It just drove smoother unlocked on fast dirt than either the old open or locked.

In the tdci defenders, it seems the OEM centre differential mechanism has been cheapened, leading to quicker wear than ever for an LT230. The ATB forever removes the freeplay of worn shims in the centre diff.

If you dont drive fast dirt and your dont have un-accounted free play in your drive train its likely you wont have much joy from the LT230 ATB

I could still be swayed to travel a bit further.

Have you done many of the front/rear diffs as well?

Yes. This is by far the best upgrade you can do to the lt230 and the rover 2 pin differential. Recently did a 2015 130 and found that the centre diff was of a ridiculous design... totally backward step...😠😠

*As your Defender is close to last model, see if the rear axle/drive flanges are one piece, if so, all is good and you wont need to do the axle/drive flange upgrade, although putting a pair of front upgraded flanges will allow a lifetime of lubing the front.

Thanks Daz
Mine has the seperate rear flanges. I have a feeling it was only the 90's towards the end that they used the one piece axles in.

I just can't come at the look of the HD flanges though.

I agree with the holiday/install concept. Thats what Im going for
