Symptoms
Low range won't select or deselect, a warning on the dash, or the shift sits half-done. Handsome Motors flags transfer case motors and actuators as a weak spot on 2002–04 trucks.
The fix, step by step
- Confirm the fault with a diagnostic scan, then unbolt the actuator motor from the transfer case, fit the new unit, then clear the codes and test the range shift with a scan tool.
- Service the transfer case fluid at the same time, because specialists note owners tend to put it off.
