At MMI we’ve spent a lot of time trying to make sense of this stupid simple part. When a ball joint works well, you won’t notice it. But even a little wiggle can cause your car to feel inconsistent and jumpy, especially at highway speeds. In building our suspensions, we’ve discovered ball joints are extremely inconsistent from batch-to-batch, and even from ball joint-to-ball joint. So how do we make them better? Let Mike walk you through some of what he’s discovered about ball joints and what MMI has been doing to improve the feel and performance of this lowly part.
