my Toyota Corolla E140 (2006-2013) makes a popping noise when driving over bumps

Solution

1. Preparation

• Gather tools and parts.
• Ensure the vehicle is parked on a level surface and secured with wheel chocks.
• Disconnect the negative battery terminal to prevent electrical issues.

2. Raise the Vehicle

• Use a hydraulic jack to lift the front or rear of the vehicle, depending on where the popping noise is suspected.
• Secure with jack stands to ensure safety while working.

3. Inspect and Replace Suspension Components

• Sway Bar Links:

  • Remove the nuts securing the sway bar links using a socket set.
  • Install new sway bar links by reversing the removal procedure. Torque to manufacturer specifications (typically around 30-40 ft-lbs).

• Struts/Shocks:

  • Remove the strut assembly by unbolting the top mounting nuts under the hood and the bottom bolts from the knuckle.
  • Replace struts or shocks with new units. Torque the bolts to manufacturer specifications (typically around 50-60 ft-lbs for bottom bolts).

• Control Arms:

  • If control arms are damaged, remove the bolts securing them to the frame and the ball joint.
  • Install new control arms and torque all bolts to manufacturer specifications.

4. Reassemble and Lower the Vehicle

• Reinstall any components removed during the inspection.
• Ensure all fasteners are tightened to specifications.
• Carefully lower the vehicle back to the ground using the hydraulic jack.
