Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, engage the parking brake, and wear safety glasses.

2. Raise the Vehicle

Use a hydraulic jack to lift the front of the Highlander.
Secure it with jack stands to ensure safety while working underneath.

3. Inspect Ball Joints

Remove the wheel by loosening the lug nuts with a socket wrench.
Inspect the ball joints visually for any cracks, tears, or excessive wear.
Check the rubber boots for any signs of damage or leaking grease.

4. Test Ball Joint Movement

Using a pry bar, apply gentle pressure under the control arm to lift it slightly.
Observe the ball joint for any excessive movement or play.

5. Replace Worn Ball Joints (if necessary)

Disconnect any components that may obstruct access (e.g., brake calipers, tie rod ends).
Remove the retaining nut from the ball joint using a socket.
Use a ball joint separator or pickle fork to detach the ball joint from the control arm.
Install the new ball joint by reversing the removal process, ensuring it is torqued to the manufacturer's specifications.

6. Reassemble and Lower Vehicle

Reinstall the wheel and tighten the lug nuts to the specified torque.
Lower the vehicle back to the ground and remove jack stands.
