Sounds like a binding issue. Make sure the arms are free and reamed out properly. A leaky shock won't cause ride height to change as only the spring is responsible for lifting the car back up. Rebound plays a minimal role here, but shouldn't be able to affect ride height drastically unless the shock is pressurized somehow.
Anyway, most likely binding somewhere. Hope that helps.
