What should be avoided when shifting into or out of an interaxle locked condition?

• A. Easing up on the throttle.
• B. Driving on smooth pavement.
• C. Using the brake pedal.
• D. Maintaining constant throttle.

Answer: (A)

When switching into or out of an interaxle locked condition, you want to keep engine speed and torque steady. Locking or unlocking the interaxle tie the front and rear drivetrains together, so any change in throttle during the shift can create a sudden load change or torque mismatch. Easing off the throttle reduces torque at the moment the system is trying to synchronize, which can cause a rough engagement or disengagement, drivetrain stress, and a less predictable shift. By maintaining a constant, moderate throttle throughout the operation, the transfer mechanism can engage or disengage smoothly, avoiding shock and wear.
