Now that you’re prepared let’s get into the testing process. We’ll cover three common methods: the visual inspection, the lift and shake test, and the pry bar test.

Visual Inspection Method 1

Visual inspection is the simplest method and can often give you a quick indication of whether your ball joints are in good shape.

1. Lift the Car: Use the floor jack to lift the front of the car and place it securely on jack stands.

Lift and Shake Test Method 2

The lift and shake test is a more hands-on approach to checking the ball joints.

1. Lift the Car: As in the visual inspection, lift the front of the car and secure it on jack stands.
2. Grab the Tire: With the wheel still on the car, grab the tire at the 12 o’clock and 6 o’clock positions.
3. Shake the Tire: Try to rock the tire back and forth. If you feel any play or movement, it could indicate that the ball joint is worn.
