The older trucks 88-94? have an front axle actuator that is filled with gas and the gas is heated and expands and that is what pushes the pin to engage the front drive shaft. Over time the gas could leak out or the heating element could take longer to heat. This is what causes the delay. The newer trucks 95-98 have an electric actuator and when engaged the motor pushes out the pin engaging the front axle much faster. You can convert the older models to the newer style actuator or install a manual cable actuator.
