Manual Hubs on Pajero

Unsure as to exactly how the super select works, but it's probally similar to the surf where it has an electronic actuator that locks in the RHS axel to the diff. Hence when out of 4wd your diff is still working and one axel is still spinning but it's not engaging the diff so to speak so extra fuel consuption would be minimal. There is of course wear on the axel and some diff components, however it was designed to work like that, just like to rear diff was designed to work all the time, so I figure, what the hell! Why fix it if it ain't broke. Besides I'm getting quite used to whacking it in 4wd when I hit a gravel road or if it's slippery and I want to show those loser comodore drivers what traction is all about at the lights!
Or when the other blokes are out in the mud and rain locking their hubs and I'm inside listening to my Mp3s with the heater on. :-))

My recollection of Super Select is that the hubs automatically engaged ( they were a chrome hub marked "Auto Hub" or something similar. When you went back to 2wd they were supposed to automatically disengage, however this didn't always happen and the way to get them to disengage was to reverse for a few yards to free them. I am working from memory here so don't bank on it; just recall reading this years ago. Give it a try, it won't cost anything.

The only complaint most have about auto hubs is their propensity to disengage at the worst possible time, under heavy load (again this was a while ago, around the time you are talking).

I had a 91 pajero for a few years. The front hubs are auto locking. They engage when you shift to four wheel drive and move forward or back a bit.

There are two lights on the dash, one to show when four wheel drive is engaged, the other to show when the hubs are locked.

I never had a problem with these hubs and I really gave the car a hard time, cape york, simpson desert twice, etc etc.

Vegie,
You would have 2H, 4H, 4HLC, 4LLC on the transfer lever.
In 2H and 4H you can drive on a hard surface.
4HLC( 4wd, High range, Lock Centre) you can drive on dirt, sand and snow
4LLC(4wd, Low range, Lock Centre) use this when the going gets tough
The vehicle can be driven in 2H or 4H on the open road. 2H means that only the back wheels are been driven. This will reduce the wear on the front diff and the extra fuel it might use. If it was raining I would select 4H as this will give you the drive to the front wheels. This gear box has the ability to run in constant 4wd and 2wd.
When 4HLC or 4LLC is selected the transfer gears are locked and the drive is split 50% front 50% rear. Fitting the manual hubs will not be of any advantage as the hubs and the gear box are doing what you want and that is to run in 2wd or 4wd.

Vegie,
Sounds like the hubs and actuators need servicing. They should fully disengage when you select H2.
The Super Select system uses vacuum actuators to engage the auto hubs. I believe it requires positive vacum to hold the hubs disengaged and releases the vacum to engage them. So if you have a vacuum leak the hubs will never disengage.
Try your rotation test with the engine running with H2 selected (in nuetral of course!)
