This is on a Wrangler...the KJ sway bar bushings have the "bump" in the U shape facing forward. The bushing itself is the rubber part under the metal bracket. You wanna quiet it up temporarily? Use silicone spray. However, others on here will argue that it will eat the bushing rubber. At the rate you're at though, i bet they're pretty much toast anyway. I spray mine with no qualms. I don't have time to replace them nowadays, and they're way shot. Having beat up sway bar bushings won't really effect anything, just make noise. Some say handling gets a little bit "tighter" with new bushings, but to me that's all mental.
