4 WD/ AWD AWD is a term applied to a vehicle that drives both front and rear axles by means of a differential between the two drive shafts. In our trucks, that differential is in the transfer case. (This is separate from the differentials that are in the front and rear of our trucks.) 4WD is a term applied to the mode where both the front and rear drive shafts are driven without a differential between the drive shafts. In our trucks, this means locking the t- case differential. In non-AWD vehicles, this usually means engaging the (otherwise completely not driven) front drive shaft. 5 Degrees Tilt In addition to keeping appropriate speed and avoiding abrupt operation, stay away from a roadside that might collapse; pay extra attention while driving steep slopes. The maximum tilt for a vehicle before it turns over when it is not in motion is somewhere between 30 degrees to left/right and 40 degrees to front/rear. When the vehicle is in motion, speed and road condition add to the instability. On rocky places with gaps, even a 5-degree tilt can cause the vehicle to flip. It is desirable to “feel” these angles in a safe and stable environment so as not to go beyond these limits in the actual driving situations. Vehicles modified to increase height or with other additions change its center of gravity and extra caution is required.
