Using your EMF ball joints is straightforward. First, make sure you have the right tools. If your ball joint press kit doesn't have a die with an ID of at least 1.93 inches and a depth of at least 0.86 inches, you'll need to buy the 7460 - 4007 Upper Ball Joint Installation Tool. When installing, avoid pressing the ball joint with a die on the cap as it can damage the cap threads. If you choose not to use the tool, EMF isn't responsible for any cap damage. For the lower ball joint, use the install tool to prevent damaging the ring when pressing it into the knuckle. Maintenance is key. Every time you change your oil, give the ball joints a couple of squirts of grease. If you start to feel movement in the joint, back out the set - screw on the side of the cap, tighten the cap, and then replace the set - screw. This can all be done without removing the ball joint from the knuckle. Over time, the internal races and pin will wear, but they're only covered by the warranty if there's a manufacturer defect. Keep up with regular maintenance to get the most out of your ball joints. And remember, EMF offers a lifetime warranty against material and manufacturing defects, but misuse or improper installation won't be covered.
