Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, pry bar, flashlight.
Ensure the vehicle is parked on a flat surface, engage the parking brake, and wear safety glasses.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Secure the vehicle with jack stands to prevent any accidents.

3. Remove Wheel

Use a lug wrench to remove the lug nuts from the front wheel.
Take off the wheel to access the suspension components.

4. Inspect Ball Joints

Visual Inspection: Look closely at the ball joints for any cracks, tears, or leaks in the rubber boot.
Movement Test: Using a pry bar, gently pry under the control arm where the ball joint connects to see if there is excessive play.

5. Reassemble

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (typically around 76 ft-lbs for most Toyota models).

6. Final Check

Perform a final visual inspection to ensure everything is correctly reassembled.
Test drive the vehicle to check for any noise or handling issues.
