4 Wheel Drive

[cbieber]

Thank you...thank you...I'm going to try it all out. Fresh snow today and new rubber.

Ok a little clarification for me...
My Pajero has the "super select" 4wd. (2H, 4H, 4Hc, N, 4Lc).
The c (as I understand) says that the center differential is locked.
So, do I need to reverse to unlock anything if I go from 4H to 2H?

I'd kind of assume I'd only need to reverse if I use 4Hc (or 4Lc)

Can someone verify that there's more than one 4wd system put onto our vehicles?

Here's my cluster:



Is there any representative lights that say the hubs are still locked (and shouldn't be)?

Get it in a week!

You do not (usually) need to reverse. Sometimes the indicator lights still blink, if they do, going into reverse may fix this.

However, what seems to work best for me is to hit the gas, then coast for a bit, so as to take the load off the transmission - allowing it to shift out. Also, popping the transmission into neutral while rolling forward works too. This is for stopping the lights from blinking on the dash - it will make sense when you try it yourself.

This DOES NOT apply to Low Range! Stop the car before engaging or disengaging low range!!

Someone (he can take credit for it if he wishes) PM'd me this:

FYI there are no hubs in a super select drivetrain; there are flanges instead (unlike primitive 4x4 drivetrain used in old L300s).
You can find more guidelines here:

And that seems correct. I guess I'll find out on Friday!

Odd this should come up right now. I've tried a couple times recently to shift my L400 into 4H while driving at about 60 kph, but it wouldn't go. I just got some grinding. Otherwise it shifts into 4h fine. Is there a top speed for shifting or something like that?

There is, but I forget if it is 60km/h or 100km/h. Someone will no doubt pipe up.

However, what I have found is that you generally can't shift while there is tension on the system. By that, I mean you still have your foot on the accelerator, which is helping bind the gears in place. So, I usually accelerate a little, then let off the gas, and then move the shift lever.

The Japanese manual says 100 km/h, but I've never tried it at that speed

FWIW, putting the van in 4WD is a bit like reducing (reefing) the sails on a sailboat; you should really do it before you need to, especially in an L400 where, as mentioned, it is kosher to do so even on dry pavement.

The easiest method I've found (after I've thought "Hmm - wet road. I should go into 4WD sometime soon") is to wait for the next red light/ stop sign, then as you pull up to a stop, put the transmission into Neutral. Then the 4WD lever can be pushed into 4H smooth as silk.

Light goes green, drop it into Drive, *Clunk* as the flanges engage, and away we go.

My 2010 Titan has the same requirement: no faster than 100 km/h to shift. And it's a rotary selection knob on the dash, not a mechanical gear shift lever on the floor.

That being said, as the previous poster wrote, one should have the forethought to engage 4WD before one is 429° into a 720° spin!
