That's a different sound than our RSB bushings.
We complained to Steeda and they sent us more bushings, which were exactly like the bushings on there. We even used the silicone lube they recommended. Just Google "Steeda sway bar squeak", it's nothing new. Every Steeda swaybar across every platform makes noise. I cut some plastic out of oil jugs and will give that a shot next, if that doesn't work we'll put the stock bar back on.
