I have an  02 Escalade that the  4wd system seems to bind up when turning at low speeds. I have had the transfercase rebuilt including the torque clutch assy.And have synthetic fluid both frt.and rear.I have also checked the tire diameter and all tires are the same size and within the  1" rolling test/tolerence.
