 |

Thought I'd gauge a concensus from people in the know on this one (Lewis et al). As the title suggests, what mode do people think is best?
Here's a link for the pro 4WD amongst us
practicalmotoring.
com.au/car-advice/mitsubishis-super-select-4x4-system-explained/
I'm a 2WD man for a starters but let's see if anything changes

A similar question was asked on Christmas day in 2016. See this post:- http://www.MDOCUK.co.uk/forums/viewtopic.php?p=382076
I put this post up in 2007 explaining the super select system and I and have always driven my Deli in 4H. It can react quicker to slippy roads and lack of traction far better and faster than a driver can.
That article ypu linked to, from 2015, gives a damned good explanation of why it is best to use it.

Unless of course you have an L300, then 4WD on a hard surface is a NO NO due to transmission windup (no centre diff).
I use Auto Select 4WD on my Dacia Duster to bring the rear wheels in if the front slip and find no difference in normal performance between 2WD and Auto 4WD.

Yes! 
Too much typing to do and I'm using three different computers at the same time. 
Post now corrected.

| So does that mean you can drive a L300 in 4h on the road ? I have a Manuel L300 and was wondering as my county council is bankrupt and is going to stop gritting the roads this year. |

From what I understand about the L300 Therefore, Generally NO - - - only when when on slippery surfaces.
There is NO centre differential fitted in the 4WD gearbox.
The L400 has a viscous oil differential clutch fitted.
When there is a difference in rotational speed between the two prop shafts, the oil locks the clutch.

For those needing an explanation of what a viscous diff does, see this post:- http://www.MDOCUK.co.uk/forums/viewtopic.php?t=49728

Correct, the OP asked the Q.
Grib then asked "So does that mean you can drive a L300 in 4h on the road ?"
Yosa then said "4WD for all my normal road driving." That applies to the L400, as you know.
So it appeared that there is confusing info. That's why I repeated what you said

Looked at that post. Interestingly, my L400 does NOT have locking hubs. - - - Optional extra

Yes it does, it has Super Select Transmission. When it is in 4H and the rear wheels lose traction the front hubs lock, otherwise the front wheels would have no drive.
Just to remind you.
Super Select 4WD
When in two wheel drive (2H) the bottom two lights come on (Rear Wheels), push the floor transfer lever forward one position to use four wheel drive (4H) and all four lights should come on. The 4H position will use 2WD until the rear wheels lose surface traction, at which time the Viscous Coupling system will auto-engage the front differential to power the front wheels on a 50-50% basis (Series 2 models use 75-25% to keep more pushing power on the rear axle). Push the lever forward again to (4HLc) and the centre orange difflock light flashes, then remain fixed on when the difflock is engaged. The dash will display the wording 'Wheel Lock' in green, to show the front freewheeling hubs are locked. If you then depress the lever and move it to the right, or left if you have a manual gear shift, into the low gears (4LLc) then all the lights are on in a fixed mode.

No Problem, at least you've got the meaning of it now.

Yes I know how the Super Select system works, thank you. My 4WD works okay
You quite clearly state "Locking Hubs" On my L400 the Front Drive shaft splines connect/slide directly into the hubs,
there is no way of temporarily disengaging/engaging them.
I have seen Baz's car that has optional Freewheeling hubs.
I don't know if that is a factory fitted part that should be on my car, or optional factory part, or aftermarket option
So - This brings a question to my mind = Is there something missing on my L400 I hope not

Bazzas hubs are aftermarket manuallu operated items.
Possibly fitted by a previous owner who didn't understand how the System worked.
