Hello All,
My 2017 Suburban has 70,000 miles on it and the service 4 wheel drive shows on the dash. The 4 wheel drive switch stays lit on the "auto" position regardless of where it is positioned. The driveline has friction on it when sharp cornering in forward and reverse. It almost seems like the passenger rear brakes are hanging up when corning forward and backward. When driving forward all friction seems to go away. After several miles of driving the wheels are not hot to the touch and does not appear to have friction on the system. There is a definite "drag" on the system when corning slowly.
I tried to research on line and could only find information on a 2004 Suburban and that seemed to be a grounding issue with wiring on the frame.
What am I looking for?
My wife and I have been very happy with our 2004 Suburban but this 2017 has been very frustrating as I have already had to put in new transmission cooling lines that weren't covered under warranty.
Please advise.
Thank you.
Mark

 

I would have a qualified tech inspect and look for problems with the brakes, the wiring for wheel speed sensors and especially the front hubs and bearings assemblies. This is a known problem causing your symptoms.

 

Without knowing what trouble codes are stored in the vehicle any sort of advice is impossible.
