No and no.
This has been covered a million plus times. All rangers do it. You need a spacer for the left side. That spring wears out faster and sags out before the right side.
Driver, battery, fuel tank all on that side (Ford's engineers don't know anything about weight distribution apparently).
If it was a broken shackle or spring it you woulds know it. The truck would't drive straight and would be ALOT lower (like 3-5" ) on that side.
