The forward front lower arm is shaped like a sickle and attaches to the front of the subframe at a 45-degree angle, and the other end connects to the lateral control arm with a ball and socket joint. First, you can press in new bushings for the strut and sway bar. This is a hydraulic bushing and, if it leaks oil, it needs to be replaced. It is rare for the large inboard bushing to fail, but it can become more compliant over time. The components that typically fail are the bushings for the strut and sway bar, and they will cause noise when going over bumps. The lateral arm extends 90 degrees from the subframe, that has a hole for the ball joint and attachment points for the sway bar links, strut and ride height sensor (the latter applies to XJ models).
