Worth haveing a chat with Ashcroft transmissions, they have an ATB for the rear , https://www.ashcroft-transmissions.co.uk/l...etrac.html, and can give advice on the front as well.

Front will be std rover diff.
I would speak to Ashcrofts for your best options. Cheers James 110 2012 XS Utility 130 2011 M57 bespoke Camper 90 2010 Hardtop 90 M57 1988 Hardtop |

Nige at Megasquirt is definitely the bloke to speak to,
Front axle will use a standard long nose LR diff, definitely worth upgrading, Nige will advise you against trying to “upgrade” the Salisbury diff as all the aftermarket (arb’s, etc. ) are significantly weaker than standard, if you’re after an updated rear diff he will advise you to change to a late td5/puma rear axle with a short nose LR diff. - he has posted a few videos comparing the Salisbury stuff on his Facebook page |

This is the accepted route and is entirely adequate for most applications, but I have to say if I wanted to build an extra-strong rear axle now I would opt for the Ashcroft custom long-nose P38 pinion housing, since it avoids the problem of the closely-spaced pinion bearings in the standard P38 pinion housing. |

Speak to Nige and have a look at some of his YouTube videos.
Failing that, Winchester Gears are worth contacting. They work with Nige on some of their offerings anyway.

Exactly, I have tried to say many a time. Running two of ^^^ on my 110s. People who don't have any options would say leave it as it was. Cheers James 110 2012 XS Utility 130 2011 M57 bespoke Camper 90 2010 Hardtop 90 M57 1988 Hardtop |

I have been runing a Quaife Torque Sensing dif for the last 30 years and over 300k ( moving it from one vehicle to the next) and it still performs faultlessly and has required no maintenance except for normal oil changes

Cheers for the replies. I had'nt planned on swapping out the axle for a later one.
What makes an ARB etc diff weaker than a standard one? Weaker when off roading/laning or just weaker overall for daily driving ? 1999 Defender TD5 110 Regards John M0VAZ Econet Station 48 no clock |

Look on the xcess4x4 Facebook page and he has a video which compares the cross pin in the Salisbury to aftermarket and other LR options,
Excuse the rubbish screenshot but as you can see the massive forget single piece one is way bigger and stronger than the little part placed next to it, the aftermarket ones use a multiple part cross pin and is much weaker than the standard Salisbury option which is take straight form a Dana axle  Click image to enlarge |

An ARB is stronger than any standard LR diff except the Salisbury. A torque biasing diff, be it a Torsen, Quaife, or Ashcroft doesn't have any cross pins and is therefore stronger than any standard LR diff, possibly stronger even than an ARB. If it came to a shoot-out between a Salisbury (with its massive construction) and an ATB, I am really not sure which way it would go, probably a halfshaft would fail long before the diff broke out in a sweat. |

I guess it depends if you want outright strength, or capability and civility?
Salisbury's are strong, but open, and mostly old and clonky! The benefits offered by a tighter, less clonky diff, or one that offers locking or limited slip may outweight the loss of strength? EDIT: All the above based on my 110, which has done 230k  |

I had this dilema myself, and spoke to Nigel for his advice on an Ashcroft/ARB locker in the Salisbury diff. As stated above he stated that the Salisbury diff was stronger than these options, which put me off them.
He also told me that he wouldn't work on the Salisbury diff, as he has sold all his tools for them. In the end I had Devon4x4 refurbish the axle, putting in a Eaton TrueTrac ATB. Its such a heavy bit of kit it is difficult to believe it would break before other parts of the driveline, but time will tell. Getting someone to work on the Salisbury if you are not prepared to do it yourself (I wasn't) might be a challenge, be warned! 2005 Td5 90 XS 1989 V8 110 CSW |

Salisbury has a strong center section, but a lot of other drawbacks and weak spots. It generally depends on intended use and tire size. If you want to go big, P38 would need some very expensive upgrades. In this case my first choice wouldbea gm 14 bolt. Salisbury axle is about 62" wide WMS to WMS, so you can pick a 63" wide 14 bolt from Cab&Chassis vehicle, or swap the hubs. I recently bought one from Germany for 350€ with detroit locker and 4.56 gears. Defender 110 SW MY2011 2.4tdci decat, no EGR
