Tools Required

• Jack and jack stands
• Socket set and wrenches
• Torque wrench
• Pry bar

Repair Instructions

Step 1: Safely Lift the Vehicle

1. Park on a Level Surface: Ensure the vehicle is parked on a flat surface.
2. Loosen Lug Nuts: Use a socket wrench to loosen the lug nuts on the wheels but do not remove them completely.
3. Jack Up the Vehicle: Use a hydraulic jack to lift the vehicle and secure it with jack stands. Ensure it is stable before proceeding.

Step 2: Inspect Suspension Components

1. Inspect Struts and Shocks:

   • Check for oil leakage on struts or shocks.
   • Press down on each corner of the vehicle and observe if it rebounds excessively.

2. Examine Bushings:

   • Look for cracks, splits, or excessive wear on bushings.
   • Use a pry bar to see if there is excessive play in the bushings.

3. Check Sway Bar Links:

   • Inspect the sway bar links for any signs of damage or looseness.

Step 3: Tighten or Replace Components

1. Tighten Loose Bolts: If you find any loose bolts or fasteners, use a torque wrench to tighten them to manufacturer's specifications.
2. Replace Worn Components: If any parts are worn or damaged (like struts, shocks, or bushings), replace them as needed:
   • Remove the old part using the appropriate socket or wrench.
   • Install the new part and torque it to specifications.

Step 4: Check Brake Components

1. Inspect Brake Pads and Hardware: Ensure that all brake components are securely fastened.
2. Replace or Tighten Hardware: If any hardware is loose, tighten or replace it as needed.

Step 5: Reassemble and Test

1. Reinstall Wheels: Place wheels back onto the hubs, hand-tighten the lug nuts, and lower the vehicle to the ground.
2. Torque Lug Nuts: Once the vehicle is on the ground, torque the lug nuts to the manufacturer’s specifications.
3. Test Drive: Take the vehicle for a test drive to confirm that the squeaking noise is resolved.

Step 6: Final Checks

• If noise persists, consider further inspection of other components such as the exhaust system and body mounts.
• Consult a professional if the noise continues after all checks and repairs.

By following these diagnostic and repair steps, you should be able to address the squeaking noise in your Toyota Camry effectively.
