TOYOTA OWNERS! Never Replace Your Leaky Axle | Fix Them Instead!

Introduction

This tutorial provides step-by-step instructions for repairing a leaky axle in a Toyota vehicle, specifically focusing on replacing the axle boots instead of the entire axle. This process is relevant for Toyota owners who want to maintain their vehicles without incurring the high costs associated with replacing axles, especially when the original parts are still in good condition.

Chapter 1: Axle Boot Kit Information

• Understanding the Axle: Toyota axles are durable and well-made. When an axle starts leaking grease, it's often unnecessary to replace the entire assembly.
• Axle Boot Kit: Purchase a kit that includes:
  • New boots
  • Grease
  • Clamps
• When to Replace: If the axle has been leaking for an extended period and shows signs of damage or noise, replacement may be necessary.

Chapter 2: Axle Leak Example and Leak Criteria

• Identifying a Leak:
  • Look for grease leaking from the axle.
  • Establish that axles should ideally be completely dry; a small amount of leakage is an early sign to repair.
• Next Steps: Remove the wheel and prepare to extract the axle.

Chapter 3: Preparing to Remove the Axle

1. Remove Speed Sensor Wire:
   • Use a 10mm and a 12mm socket to loosen the sensor wire.
2. Remove Axle Nut:
   • Grind the top of the axle nut for easier removal.
   • Use a 30mm 12-point socket to unscrew the nut.
3. Loosen Ball Joint:
   • Remove two nuts and one bolt from the ball joint.
4. Support Control Arm:
   • Use tie straps to secure the control arm out of the way.

Chapter 4: Toyota Axle Design

• Understanding Axle Removal:
  • Driver's side axles pop out without additional fasteners.
  • The passenger side may require more effort due to design.
• Boot Replacement Strategy:
  • Always replace both inner and outer boots.
  • Loosen the clamp on the boot to pull half the axle out without disturbing the bearing.

Chapter 5: Axle Half Removal

1. Remove the Outer Boot Clamp:
   • Use side cutters to carefully cut the clamp.
2. Extract the Axle:
   • Expect some grease to leak; use a catch pan to limit mess.
3. Clean the Area:
   • Clean up excess grease to avoid contamination.

Chapter 6: Axle Tear Down

1. Remove the Spider Bearing:
   • Use a specialized tool to remove the clip holding the spider.
   • Tap gently with a hammer to persuade it out, ensuring not to damage the axle.
2. Inspect the CV Joints:
   • Check for rust or excessive wear. If present, consider replacing the axle.

Chapter 7: New Axle Boot Kit Contents

• Boot Selection: Identify the correct boots based on the protrusions for the spider bearings.
• Grease Types: Differentiate between the watery and thicker greases, using the watery one for the outer boot and the thicker one for the inner boot.

Chapter 8: Important CV Clamp Information

• Choosing Clamps: Ensure clamps are the correct diameter for both inner and outer boots (e.g., 102.5mm for inner).
• Do not Reuse Old Clamps: Always use new clamps provided in the kit.

Chapter 9: CV Boot Tool Information and Tool Demo

• Using Crimping Tools:
  • Employ a crimping tool to secure the clamps. Aim for a tight fit where the ends nearly touch.
• Alternative Methods: If using a less specialized tool, be patient and avoid twisting the clamps.

Chapter 10: Reassembly Continues

1. Reinstall the Boot:
   • Place grease inside the boot before sealing.
2. Secure the Clamps:
   • Ensure clamps are seated properly and aligned for aesthetics.
3. Final Tightening:
   • Use the appropriate tool to tighten clamps securely.

Chapter 11: Reinstallation Tips

• Reinstall the Axle:
  • Push the axle back into the hub while ensuring the boot sits evenly.
• Tighten All Components:
  • Reattach all parts, including the ball joint and speed sensor.
• Final Cleanup:
  • Clean any remaining grease and reattach the wheel.

Chapter 12: Different Model Differences

• Model Variations:
  • Be aware that some models (specifically 2014 and newer) may have different boot designs.
• General Advice:
  • Most Toyota models follow a similar axle boot replacement process.

Conclusion

Replacing leaky axle boots in a Toyota can save you money while preserving the integrity of your vehicle's axle. By following these steps, you can successfully complete the repair while avoiding costly replacements. Ensure to keep your workspace clean and organized throughout the process for the best results.
