| Video Discription | See the operation and power flow of a part-time 4WD front differential and transfer case Timeline: 0:00 Introduction 0:39 The Toyota JF1A electric shift transfer case and parts 2:58 The front driveshaft (Propeller shaft) 3:05 The front Automatically Disconnecting Differential (ADD) front axle 6:21 Transfer case operation 7:42 2WD mode 7:54 The shift into 4WD mode high range 8:36 The shift into 4WD mode low range 9:50 The shift back into 4WD mode high range 10:09 The shift back into 2WD mode 11:15 Operation of the ADD front axle 11:43 2WD mode of the ADD front differential 14:19 The function of the ADD 15:12 The shift sleeve and fork of the ADD 15:54 Two shafts spinning in opposite directions 16:03 The order of events required to connect the two shafts together 16:55 Shifting the ADD into 4WD mode 19:17 Front ADD actuator electrical signals 20:02 The order of events required to engage 4WD operation 20:40 The order of events required to disengage 4WD operation Weber State University (WSU) - Automotive Technology Department - Transmission Lab. The operation and power flow of this part-time 4WD front differential and transfer case are very similar to others built by General Motors, Dodge, Ford, Toyota, Nissan, etc. This 4WD System is typically used in 2007 through 2013 Toyota Tundra trucks. This video helps satisfy the requirements of the following NATEF Tasks: 3.F.5 – 4WD/AWD - Diagnose noise, vibration, and unusual steering concerns; determine necessary action - Priority Level 3 Questions for teachers: 1. Is this transfer case used on a vehicle with a transversely-mounted engine or a longitudinally-mounted engine? 2. What are the two modes of transfer case operation? 3. What are the two ranges of transfer case operation? 4. How are the modes and ranges selected in this transfer case? 5. The ADD connects and disconnects which two parts? 6. What are the two modes of the Automatically Disconnecting Differential (ADD)? 7. List the order of events required to engage 4WD operation 8. List the order of events required to disengage 4WD operation 9. Tell me one thing you learned from this video http://www.weber.edu/automotive This video was created and edited by John D.
