Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, ball joint separator, torque wrench, socket set, safety goggles, gloves.
Ensure the vehicle is on a level surface and the parking brake is engaged.

2. Lift the Vehicle

Use the jack to lift the front of the vehicle.

3. Remove Wheel

Use the lug wrench to remove the wheel bolts and take off the wheel for access to the suspension components.

4. Inspect Ball Joint

Visually inspect the ball joint for any signs of wear, such as cracks, tears, or excessive rust.
Use a ball joint separator to check for play; insert it between the control arm and ball joint and apply pressure to see if there is any movement.

5. Replace Ball Joint (if necessary)

Tools Required: Ball joint press, new ball joint, grease, torque wrench.
Remove the retaining nut and bolt from the ball joint using a socket set.
Use the ball joint press to remove the old ball joint from the control arm.
Install the new ball joint, ensuring it is seated correctly in the control arm.
Torque the retaining nut and bolt to manufacturer specifications (consult the service manual for exact torque values).

6. Reassemble

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from jack stands and torque the lug nuts to the specified value.
Test the suspension by gently bouncing the front of the vehicle.
