In this video I deal with a Chevy Avalanche that arrived with the customer complaint of intermittent no 4X4 operation and a service 4X4 message on the drivers information display. After pulling a code C0378 I look deeper into the 4X4 control system in attempts to locate the cause. I'll show the process for testing and replacing the front differential actuator as well as servicing the transfer case and front differential fluids. Watch this video for more diagnostic information and the fix!
This information is helpful for most late model Chevy, GMC and other GM trucks and SUV's with similar symptoms/codes.
