Does anyone know if 4WD issues are covered in the 100K powertrain warrenty? My Tahoe keeps displaying "Service 4WD". The truck likes to disengage its 4WD when ever it likes or engage in 4WD Low while driving. I recently have had the oil changed and the the Tech. said that the rear differentials were very low in oil. He put "about 8 oz. in and said that there did not appear to be any leaks or cracks. Also, while in reverse or backing up the Tahoe squeeks, sounds like metal on metal squeeking. My mileage is 72K and just wondered in it could be covered by the Powertrain warrenty? Any help would be GREATLY appreciated! Thanks, Todd:mpr:
