Repair Instructions

If you have confirmed that the drive shaft is failing, follow these steps for repair or replacement:

Tools and Parts Required

  • Socket set
  • Wrench set
  • Jack and jack stands
  • Torque wrench
  • Replacement drive shaft (if necessary)
  • U-joint replacement kit (if applicable)
  • Grease (for U-joints)

Steps to Replace the Drive Shaft

  1. Safety First:

    • Park the vehicle on a level surface, engage the parking brake, and wear safety goggles.

  2. Lift the Vehicle:

    • Use a jack to lift the Highlander and secure it with jack stands.

  3. Remove the Drive Shaft:

    • Disconnect the Battery: Remove the negative terminal to prevent electrical shorts.
    • Unbolt the Drive Shaft: Use the socket set to remove the bolts connecting the drive shaft to the differential and the transmission. Keep track of the bolts for reinstallation.
    • Remove the Drive Shaft: Carefully slide the drive shaft out of the transmission and differential.

  4. Inspect U-Joints:

    • If you are replacing U-joints, use a press to remove the old ones and install new ones following the manufacturer’s specifications.

  5. Install New Drive Shaft (if replacing):

    • Position the New Drive Shaft: Align it with the transmission and differential.
    • Bolt It In Place: Use the original bolts or new ones to secure the drive shaft at both ends. Torque the bolts to manufacturer specifications (refer to the service manual for the specific torque values).

  6. Reinstall the Battery:

    • Reconnect the negative terminal of the battery.

  7. Lower the Vehicle:

    • Carefully lower the Highlander back to the ground.

  8. Test Drive:

    • Take the vehicle for a test drive to ensure there are no vibrations or noises and that it drives smoothly.
Final Thoughts

If you are not comfortable performing these repairs yourself, it is advisable to consult a professional automotive technician. Regular inspection of the drive shaft and associated components can help prevent issues and ensure the longevity of your vehicle.
