so whats should i put in the back

front, do i need to change axials at the same time? CV etc etc how can i take this?

Not too many choices with the rear Salisbury at this stage. McNamara was the best but not sure they produce them anymore.There are ARB airleakers or you could wait for Ashcrofts to finish developing the Salisbury version of their New locker. The original 110 rear halfshafts are much better quality than later Defenders and don't really require upgrading unless you are brutal. CV joints are also better but can be broken. Upgrade as or if needed. The inner 10 spline front halfshafts of course will need upgrading to 24 spline regardless of front difflock brand you choose.

if i upgrade to 24 spline will i need to change the CVs?

No, the upgraded front inner shafts will be 24 spline at the diff end and standard 23 spline at the CV end.

What he said. I understand MR Automotive have started making Maxidrive lockers which are also an option.

The advantages of MD:
- Locker comes with upgraded halfshafts (integral to the locking mechanism),
- Doesn't require a separate air source (works off the vacuum pump)
- MD lockers have a reputation for being (almost) indestructable.
- The actuator mechanism is not preloaded, so if you lose vacuum with a locked axle, it will stay locked. This can be a disadvantage as well, as you may have to unlock it manually. I've heard it can be "sucked" back into unlocked position but have not had first hand experience, you can use compressed air at low pressure (e.g tyre air) to do the same, or dismantle the actuator and unlock it manually.

The disadvantages:
- Installation requires welding on the axle casing to mount the actuator - shiny cylinder in pic below (exxy if you can't do yourself - approx 10 hours labour),
- Can be a bit slow to engage (actuator works off 15 psi vacuum, versus 90 psi compressed air for Airleakers). Not much of an issue for a rear locker IME.

I have MD lockers front and rear, and to be honest, I seldom have the need to use them in anger, primarily due to my tame driving.

I have gone with a Truetrak LSD in the front with strengthened axles and a Maxidrive in the rear. I bought a whole disc braked rear end and sent it to MR Automotive to have the locker fitted.

No idea how this set up works in practice. It will be some time before I get to drive the car but I'm keen to find out.

I have an ARB front and rear in the 110, with MD/HTE upgraded halfshafts - only because I got them cheap as Offender90 didn't need them anymore.

No complaints. I had to remove and clean the electro-pneumatic valves once, after they gummed up with mud and oil.

I have a MD locker in another vehicle. I would be happy with either.

If I was buying again I would be tempted to go for MD or ashcroft over ARB. However Ashcroft aren't (yet) making sals lockers.

Simple is best IMO; In my County I have a Disc brake Defender 130 Sals Detroit locker and maxidrive axles rear, Detroit trutrack and factory 24 spline Defender axles and CV's front, (About to fit a secret front differential upgrade in the new year....). I am running 33" BFG muds BUT I am quite easy on my vehicle. I haven't broken anything yet even when the diffs were open and stock standard.
I don't have any steering or handling issues BUT you do know the trutrack is there if pushing it into or out of corners.

ok did there message thing on there web site, but as this is Australia it will probably take the best part of a month for them to get back to me LOL
