How do i use four wheel drive in the snow - 1993 Mitsubishi Montero

SOURCE: Jeep Quadratrack does not shift into 4 wheel drive

the quad trac is an alltime 4wheel drive system. it does have a control module that helps transfer the power from front to rear. if it is a 2008 it should be under warranty and you can have it checked out for proper operation

SOURCE: Difference betweeb 2wH part time 4wd and 2wH + full time 4wd

The difference between 4WD Full-Time and 4WD Part-Time is not exactly what one would guess simply from the names without knowing. The main difference is basically an added differential in the transfer case vs. the front and read driveshaft being locked together.

Here's what that means to you.

4WD Full-Time (open differential in transfer case)- Is great for snow and ice. It is safe to leave locked into this mode anytime, even on dry pavement or highway.

4WD Part-Time - This is the traditional type of 4WD that you have in vehicles. It will give you added traction offroad, it's good for mud, rock climbing, snow... It is actually not as good on ice as 4WD Full-Time. Do not drive on dry pavement, especially around corners, in this mode. It can cause major damage, and at the least will cause unnecessary wear to the components.

I hope this helps.

On the full size, the front actuator is electric, not vacuum.

When in 4wd mode, a switch on top of the transfer case conducts 12 volts out to the actuator. Wire #50 (brown) is the 12v feed, and it conducts to the light blue wire (#900) to the actuator.
When shifted out of 4wd, the switch opens up and no voltage goes to the actuator.

Check voltage at the connector for the front actuator (at the front differential - it looks like a large bullet that threads into the front diff.) If it has 12 volts, check the transfer case switch and the power feed to the transfer case.

I'll assume it is the actuator, if the plug to the actuator is not getting 12 volts when in 2wd.
The way this actuator works, is it is a sealed chamber that gets heated by voltage. When it heats, the pin in the end swells and pushes a shift fork in the front differential. The shift fork engages a spline on the passenger side of the differential, and boom! you have 4WD, with out the 12 volts you have 2WD.

GM offered an upgrade to this actuator that is a motor instead of a heated device. However, it requires a small harness addition, a spacer, and a new actuator. It is about a $150 to $200 option.

If I were you, I would buy a new heated actuator. They are available at most auto parts stores, and are about $90. They are also on eBay for about $55 plus shipping. These are very easy to change - just thread out the old one, and thread in a new one.

Good luck, That actuator is usually the problem 90% of time but check the fuse to the 4X4.

See vacume pipes at the front wheels. sound like it is broken or pulled out by snow. there is 2 pipes one for brakes on calliper and one for vacume suction to engage or dis engage 4 wheel drive. Enjoy. Willem SA

Four wheel High is what you need to use in snow. It is similar to your regular driving experience but your speeds should not exceed 45-50 mph. Shift through your normal gears as necessary and drive with appropriate caution. Four wheel High should be used only as long as driving conditions warrant, using it otherwise can cause unnecessary wear on your transmission and drive-train as well as lower fuel economy.

Four wheel low is used for pulling out of a ditch if you are stuck, going through deep mud or rock crawling. Four wheel low will also cause your vehicle to lurch every time you press the gas pedal.
