with maxi you need to cut and weld the diff....so a bit more involved
I have front and read ARB's with hy-tuff axles and flanges, the axles and flanges have been fitted for maybe eight years with zero sign of wear. never had an issue with the lockers apart from damaging an air line in the first month of ownership, carried joiners ever since and never needed them
Ashcroft is also another option Ashcroft Transmissions
quite surprised all the auto locker guys haven't chimed in

I have a Maxidrive on my Sals diff. Love it.
For Rover Diffs (e.g. my front, which I'll do one day) I reckon the e-diff is the way to go.
The 130 and HD 110 Sals uses thicker wall tubes than the standard 110 Sals.Quote:

The downside of the Maxi one is fitting (cutting the axle tube and welding the actuator block) and supposedly it can be a little slower to engage.
The other alternative is a Detroit Locker.
Cheap and easy to fit and no air compressor, air or vacuum lines or wiring to run as with the Malay activated lockers.
If you need to buy the axle then I would build a 35 spline sals w-ARB or McNamara locker if you can afford it.
It will be 1-2k more than a sals MD locker but apart from changing the oil you will never need to worry about it again.
FWIW I have one sals with an MD Locker (fitted myself) and one with an ARB locker and 24 spl MD/HTE axles. I can't say I have a preference between the 2. The MD is significantly slower to disengage at times but that has never been a problem.
Following on from Rick's response to the 130 tube thickness. I have a regular 110 sals not the HD. Of the 3 or 4 examples i have seen (photos only) of a sals falling apart each were where the tube fits to the diff housing. There are various causes for a failure i.e., the diff housing bearing the unsprung weight of the wheels when stranded or repetitive flexing forces of corrugations or being over laden. To my lay logic the thickness of the tubing would not have likely prevented that type of failure from those causes.
There is an Eaton E-Locker for the sals, same for the P38 and rover diff centres. I went with the e-locker for the front. I had trouble with the first centre but the replacement has been trouble free. A click of a button on, click of a button off. No air lines, no compressors.
If your maxi is sticking when engaging and disengaging it could be the spring tension. Too much tension the vacuum won't overpower the ball in the detent in the actuator. Same when disengaging. It's something else to consider if you are experiencing slow response from your maxi. Personally I have no delay disengaging. It usually disengages within half rotation of the wheel. The difference with the maxi (light on when engaged) and ARB, TJM, Ashcroft etc is the light is independent to the engagement or disengagement. You might be experiencing the same minor delay with the air locker but you wouldn't know it. Rider to that is the front locker when the wheels are turned left or right. Most front lockers will not disengage freely in that situation because of the variable tension (on the axle) from each wheel at the diff centre. i'm referring to the situation as you move to the extremes of steering lock not necessarily just off centre.

Anyone who uses an MD locker for serious offroading knows that the light goes off instantly, however in many cases (especially when cornering or windup) that there will be a 2nd hiss later when it disengages fully. (I use 15psi compressed air to actuate my MD locker as I have no vacuum system - so no shortage of pressure to overcome detent spring tension).Quote:

I was always under the impression that the light only goes off when the locker disengages and only comes on when engagedQuote:

ARB require air pressure to remain locked, is rather a disadvantage than an advantage. The reason is that if you are negotiating an obstacle that requires the locker and you either, pull an air line or lose the compressor you are immediately unlocked. This may or may not be associated with an indication on the dash.
With the Maxi-drive you have to command the change. i.e. it will remain in it's locked state until you command it to unlock.
In regard to the light on the Maxi, it is a simple electrical connection attached to the actuator, when the actuator/slider is in the fully locked position it closes the circuit to ground and the light on the dash illuminates. When the actuator moves to unlock the circuit is broken and the light goes out.
