I purchased a used 2002 Suburban 1500 4x4. Is there a way to visually determine if this vehicle has the Speed-Sensitive Steering option? I'm having some power steering issues, with very hard resistance to a right turn for the first mile or so of operation in the morning. It is more pronounced at speeds between about 15 to 30 mph, negliable at very slow speed or stopped. Once driven, and cycled left/right a few times it operates normally. Dealer cannot seem to find the problem. I'm trying to use process of elimination before just changing the power steering gearbox. (I doubt if it is the pump, because the problem is always a right turn and always within a speed range, and the pump itself should not care.)
Any help on the speed sensitive steering system, or the above problem very greatly appreciated.
