I can't speak to whether or not to replace a cartridge bottom bracket, but I'd at least remove it to inspect the bottom bracket shell. Inspect for rust, water intrusion, and sediment. If it's a steel bike. Probably not for aluminum, ti, or carbon fiber.
Anyone want to chime in about applying a rust preventer?
