4x4 Issues

[Matt06Z71]

I have a 2006 Z71 has there been alot of issues with the 4 wheel drive system messing up. I been having problems with it going into 4 wheel drive by its self or getting stuck in 4 wheel drive by its self or just not working. Any help would be nice. It was in dealer 2 weeks ago for 4x4 acuator motor replacement but it started doing the same thing again.

Im starting to have the same issue. I have not had the actuator replaced yet, but was wondering if that could be the problem or is there something else to look for?

Everything I have read up on suggests its the encoder sensor. The next thing would be the actuator and then the button switch.
