Solution

1. Preparation

Gather necessary tools and parts, ensuring the vehicle is on a level surface.
Tools required: Jack, jack stands, tire iron, ratchet and socket set, ball joint separator tool, grease gun (if re-greasing), safety gloves, and safety glasses.

2. Raise and Secure Vehicle

Use the jack to lift the front of the Highlander.
Place jack stands securely under the vehicle to ensure stability before proceeding.

3. Inspect Ball Joints

Visually inspect the ball joints for cracks or damage.
Grasp the tire at the 12 o'clock and 6 o'clock positions, rocking it to feel for play.
Repeat the rocking test at the 3 o'clock and 9 o'clock positions.
If excessive movement is detected, or if the ball joint boot is damaged, replacement is necessary.

4. Replace Worn Ball Joints (if applicable)

Remove the wheel using the tire iron.
Disconnect the ball joint from the control arm using the ratchet and socket, removing any retaining clips if present.
Use the ball joint separator tool to detach the ball joint from the steering knuckle.
Install the new ball joint in reverse order, ensuring to torque all bolts to the manufacturer’s specifications (typically around 40-50 ft-lbs for ball joint bolts).
Reattach the wheel and lower the vehicle back to the ground.

5. Re-grease (if applicable)

Use a grease gun to apply grease into the new ball joint if it is serviceable.
