test drives 5 / 6

  1. what does the plunger do in the front axle disconnect system? Moves the forks and sleeve

  2. can be manual or automatic? Locking Hub

  3. Must turn knob to engage or disengage. Locking Hub

  4. Uses a shift collar. Front axle disconnect

  5. entire front axle becomes inactive. locking hub

  6. what happens when the spring-loaded vacuum hubs engage? Axle shaft connects to the wheel hubs

  7. uses an electric or vacuum actuator. Front axle disconnect

  8. what does the check valve do for the integrated wheel end system? Maintains vacuum in case of component failure in another system.

Part time - RWD system with two-speed transfer case

full time - permanent 4WD system

chain drive - links the front and read drive shaft

planetary gear set - used for gear reduction when 4WD low is selected

  1. In NEUTRAL mode, the range selector moves the synchronizer sleeve to engage the planetary gear set. False

  2. In 4WD LO mode, the high/low sleeve disengages the planetary gear set. False

  3. In 2WD mode, the mode fork prevents the synchronizer from engaging the front drive sprocket. True

  4. In 4WD HI mode, the synchronizer sleeve locks the front drive sprocket to the rear output shaft.  True 

  5. 2WD - the control module receives the input from the switch and the encoder, and rotates the encoder in the clockwise or counter-clockwise direction.

      4WD - the control module receives signals from the TR sensor, encoder, VSS sensor, and BP sensors to rotate the encoder. 

      4WD AUTO - the control module engages the multi-disc clutch plate if there is a difference in speed between the front and output shaft 

     

  1. a damaged outer cv-joint may cause a clicking noise. True 

  2. Oversize tires may cause worn differential side and pinion bearing. False 

  3. Incorrect suspension height may cause a launch shudder. True 

  4. If the driveshaft is bent or out of balance, it may cause Vibration. 

  5. a bad front axle U-joint may cause a clicking noise. True 

  6. If the u-joints lack lubrication, it may cause squeaking noise. 

  7. Increase in the u-joint angle due to excessive pinion nose movement may cause Shudder.
