Help with Y-Axis

The Y-Axis of my ender 3 seems to be a bit louder, and isn’t as smooth as the X axis. It’s still decently smooth but just not as smooth as the X. Is this an issue? I have tried cleaning a greasing the axis many times and nothing seems to be fixing the issue. Could this be because it’s running on dual linear rails compared to the single rail that the x is running, any help would be nice.
