I no longer have the 899 so I cannot check but I believe it's normal... the sprocket carrier has its own bearings and spacers, which ultimately determine its exact position relative to the wheel. In other words, if you remove the large pins that go into the rubber bushings, the carrier would still stay where it is and would not wobble... it would just spin freely on the axle. If you didn't mess with bearings or spacers, then likely there is nothing to worry about.
