How To Replace Torn CV Boot On An All Wheel Drive Car (2006-2011 Lexus GS, IS, ES)

Introduction

This tutorial will guide you through the process of replacing a torn CV boot on a 2006-2011 Lexus all-wheel drive vehicle. A damaged CV boot can lead to grease leaks and potential damage to the CV joint, so it's important to address this issue promptly. By following these steps, you can save money and learn a valuable skill.

Step 1: Prepare the Vehicle

• Jack up the car: Lift the driver's side of the vehicle using a jack to access the wheel and CV boot.
• Remove the wheel: Take off the wheel on the side with the damaged CV boot.

Step 2: Assess the Damage

• Inspect the CV boot: Look for signs of tearing or grease leakage. A torn CV boot often leads to clunking or clicking noises during turns.

Step 3: Gather Tools and Parts

• Tools required:
  • Dial caliper
  • Ratchet set
  • Breaker bar
  • Pliers
  • Bungee cord
  • Vise
  • Torque wrench
• Parts needed:
  • New CV boot kit (includes grease, clamps, and instructions)
• Tip: Purchase the kit from a reliable source like Rock Auto to save money.

Step 4: Remove the Caliper

• Loosen caliper bolts: Use a 17mm socket to remove the two caliper bolts.
• Support the caliper: Never let the caliper hang from the brake line. Use a bungee cord to secure it to the upper control arm or spring.

Step 5: Remove the Rotor and Hub

• Remove the rotor bolt: Use a 3/16" socket to take off the bolt that holds the rotor and hub.
• Remove the rotor: If it's stuck, thread bolts into the rotor holes and tighten them to push it off.

Step 6: Disconnect the Wheel Speed Sensor

• Remove the bracket: Use a 10mm socket to detach the bracket holding the wheel speed sensor to prevent tension while removing the control arm.

Step 7: Remove Axle Components

• Remove cotter pin and nut: Pull out the cotter pin and loosen the 17mm nut without removing it completely.
• Cut off old bands: Use dikes to snip the old bands securing the CV boot.

Step 8: Remove the Old CV Boot

• Pull off the boot: Cut the boot away carefully. It may be necessary to discard it in pieces.
• Catch any bearings: Use a bucket or rag to catch any ball bearings that might fall out.

Step 9: Install the New CV Boot

• Clean the axle: Make sure to clean the axle and surrounding area thoroughly.
• Install the new boot: Slide the new boot onto the axle, ensuring it fits snugly. Use grease to help it slide into place.

Step 10: Secure the New Boot

• Add clamps: Use the provided clamps to secure the new boot. If you don't have the right tool, improvise with a suitable method to tighten them.
• Pack with grease: Fill the boot with grease, ensuring the bearings are well-lubricated.

Step 11: Reassemble the Components

• Reinstall the axle: Carefully reinsert the axle into its position.
• Torque the nut: Tighten the axle nut to the specified torque (217 ft-lbs). If your torque wrench can’t reach this, tighten it as much as possible without overstraining components.
• Secure cotter pin: Insert and secure the cotter pin after tightening the nut.

Step 12: Reassemble Everything

• Reattach the rotor and caliper: Replace the rotor, and reattach the caliper, torquing it to 58 ft-lbs.
• Reinstall the wheel: Put the wheel back on and lower the vehicle back to the ground.
