Some Chevy trucks are sold with four-wheel drive systems. Four-wheel drive transfers power to all four wheels, rather than just the rear two -- this adds to traction. In addition, the four-wheel drive system has a low gear ratio that’s great for extreme conditions and hills. Transfer is accomplished with either a manual lever on the floor, or a knob, depending on model. Sometimes the 4x4 can be difficult to engage, or won’t engage at all. However, this can be rectified.
Allow time for the 4x4 to engage if the ambient temperature is low. Cold temperatures, particularly below freezing, can mean difficulty transferring from two-wheel drive into four-wheel drive high. Most transfers will take place if you slow down, or stop. Just remember that easy transfers at speed in warm weather become harder and slower as it gets colder.
Use quick motion with the manual lever-type transfer if shifting is difficult. Slow movement of the lever will cause gears to grind excessively.
Shift the gears momentarily to the “Drive” position and then back to “Neutral” if the transfer case lever is in “Neutral” and you have difficulty engaging a transfer case mode like four-wheel drive, or two-wheel drive. This realigns the gear teeth in the transfer case.
Use force on the shift lever to move from two-wheel drive to four-wheel drive while the truck is moving. Make one swift and firm movement at any speed up to any posted speed limit for best results in engaging.
