my Toyota Highlander XU70 (2020-Present) makes a popping noise over bumps, what is it

Solution

1. Preparation

• Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and a flashlight.
• Park the vehicle on a level surface, engage the parking brake, and wear safety gear.
• Disconnect the negative battery terminal to ensure safety.

2. Lift the Vehicle

• Use the jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
• Secure the vehicle with jack stands to ensure stability.

3. Inspect and Replace Components

• Inspect Struts/Shocks:
  • Remove the wheel to gain access to the suspension components.
  • Check for any leaks in the struts or shocks; if found, replace them.
• Replace Worn Sway Bar Links:
  • Disconnect the sway bar link from the sway bar and lower control arm using a socket and wrench.
  • Install new sway bar links by reversing the removal steps, ensuring they are torqued to manufacturer's specifications.
• Replace Bushings if Necessary:
  • If bushings are worn, use a pry bar to remove the old bushings from the control arms.
  • Install new bushings, ensuring they are properly seated.

4. Reassemble and Lower Vehicle

• Reattach the wheel and ensure all lug nuts are tightened to the manufacturer’s torque specifications.
• Remove jack stands and lower the vehicle back to the ground.
