I have a 1969 Camaro 396 A/C car. I just finished a complete restoration and upgraded my steering gear box to the 3rd generation A-1 Cardone 276550 box as well as the adapters and rag joint from Lee Manufacturing. Both of the hoses are brand new. I have purchased three power steering pumps two 20-6000 and one AC Delco pumps. All of the pumps have overheated and the bearing has failed. I have a 3941107 Power Steering Pulley on the power steering pump. I replaced the pump and the hoses today, only to burn the front bearing out again. The pump is about 300 degrees after about ten minutes of running. I never had the car on the ground today. What could I be doing wrong? Please Help.
