1
Visual Inspection**: Check for any visible signs of wear or damage, such as cracks, tears in the rubber boots, or rust.
2
Shake Test**: With the vehicle lifted, grasp the wheel at the 12 o'clock and 6 o'clock positions, and shake it to check for excessive movement.
3
Wobble Test**: Repeat the shake test at the 3 o'clock and 9 o'clock positions to assess lateral play.
4
Suspension Loading**: Bounce the front suspension up and down while observing if the ball joint is moving excessively.
5
Listen for Noises**: While the vehicle is on the ground, turn the steering wheel and listen for any unusual noises coming from the suspension.

Solution

1. Preparation

Gather Tools:
- Jack and jack stands
- Wheel chocks
- Torque wrench
- Socket set
- Pliers
- Grease gun (if re-greasing)

2. Lift the Vehicle

Sub-steps:
1. Park the vehicle on a level surface and engage the parking brake.
2. Loosen the lug nuts on the front wheels slightly.
3. Use the jack to lift the front of the vehicle and secure it with jack stands.
4. Remove the front wheels.

3. Inspect Ball Joints

Sub-steps:
1. Visually inspect the ball joints for damage, such as torn boots or excessive rust.
2. Perform the shake and wobble tests as detailed in the Diagnostic Steps to assess for play.

4. Replace Ball Joints (if necessary)

Sub-steps:
1. Remove the retaining nut from the ball joint using a socket set.
2. Use a ball joint separator or pickle fork to detach the ball joint from the control arm.
3. Install the new ball joint in reverse order, ensuring it is seated properly.
4. Torque the retaining nut to the manufacturer’s specifications (typically between 30-60 Nm, check service manual).

5. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the front wheels and hand-tighten the lug nuts.
2. Carefully lower the vehicle from the jack stands using the jack.
3. Once on the ground, torque the lug nuts to the manufacturer's specifications (usually around 120 Nm).
