Drive Train Axles Bearings problem
2007 Chevy Tahoe V8 Four Wheel Drive 57000 miles
got in this a.M. Put vehicle in reverse and warning message " service 4 wheel drive system" came on and felt like I had the brakes on. Tried to reset the drive mode (had it on auto) but would not reset. Tiny lights were on on the dial for 4 wheel drive and auto. Could not get out of my driveway in reverse. Is this a sensor problem or something else. Have only used 4 wheel drive once and never went over 30 mph. Had no problem driving home last night but had this happen this morning.
