• Loosen the Ball Joint Nut: Before separating the ball joint from the spindle, loosen the nut but do not remove it completely. This will help prevent the spindle from suddenly dropping when the ball joint is separated. Applying penetrating oil to the threads can make this step easier, especially if the nut is corroded. A breaker bar may be necessary to loosen particularly stubborn nuts. Leaving the nut partially engaged also provides a safety measure, preventing the spindle from falling abruptly and potentially causing injury or damage.
• Separate the Ball Joint from the Spindle: Use a ball joint separator tool (pickle fork or ball joint press) to separate the ball joint from the spindle. A pickle fork can damage the ball joint boot, so use a ball joint press if you plan to reuse the ball joint (though this is generally not recommended). The ball joint separator tool applies pressure to the joint, forcing it apart. A pickle fork is a wedge-shaped tool that is hammered between the ball joint and the spindle, while a ball joint press uses a screw mechanism to apply controlled pressure. If you are replacing the ball joints, the pickle fork can be a faster option, but it will likely damage the boot. If you are trying to salvage the ball joint, the press is the preferred method.
• Remove the Ball Joint Retaining Hardware: Depending on the Ford OBS model, the ball joints may be secured with rivets or bolts. If riveted, you'll need to grind off the rivet heads and punch them out. If bolted, simply remove the bolts. Grinding rivets requires caution to avoid damaging the control arm. Use a grinding wheel or a cutting torch to carefully remove the rivet heads. Once the heads are removed, use a punch and hammer to drive the rivets out. If the ball joints are secured with bolts, make sure to use the correct size wrench or socket to avoid stripping the bolt heads.
• Press Out the Old Ball Joint: This is where the ball joint press comes into play. Position the press correctly and carefully press the old ball joint out of the control arm. Ensure the control arm is properly supported to prevent bending or damage. The ball joint press uses a screw mechanism to apply controlled pressure, forcing the ball joint out of the control arm bore. It's crucial to ensure that the press is properly aligned and that the control arm is securely supported to prevent damage. If the ball joint is extremely stubborn, applying heat to the control arm around the ball joint bore can help to loosen it.

3. Installing the New Ball Joints
