No, you’re not looking at a red urethane bushing like that commonly associated with the aftermarket. This bushing in the upper-control-arm assembly appears to have been liberally coated in orange paint. While we might first surmise it’s a paint marking to identify proper or finished installation, such indicators are rarely more than a swath or daub made by a stick or brush. This color is more likely a liquid material that the bushing was dipped into prior to assembly, which made it easier to press into place. It may also be a compound intended to ward of squeaks and/or rust during normal use. The cross-shaft retaining nut has a bright finish.
