I changed the Rack in my 2000 X last week, The Job was not as bad as I thought it would be but one thing has me worried, the reman rack & pinion came with a card that stated that the "Check Valve" needs to be pulled from the old unit and installed in the reman rack prior to installation in the truck. As I prepared to do this I found that there already was a check valve installed in the new unit so I omitted the step. The card does not say anything about removing an existing "Check valve" from the reman unit so I figured that everything was OK. As I was boxing up the original unit to return for the core I noted a significant difference in design, the original factory rack was technically not equipped with a check valve but rather a check choke. It has a small hole in the popit disk that allows free flow from the high pressure line into the rack but also allows an orifice restricted flow back up from the rack to the pump. The steering seems to work fine but I am seriously considering pulling the rack back out to install the original device.
Does anyone know why the factory did not use a standard check valve in the high pressure supply to the rack?
