Hi, I have a 2002 gmc sierra 1500 slt 4x4. The service 4x4 light keeps coming on and I just serviced the transfer case and gear boxes. The light still comes on. Any ideas as to why this keeps happening?

You need to have the computer scanned. It is trying to tell you there is an issue with a sensor, the actuator. That light isn't to tell you to change the oil in the transfer case.
