      Hi everyone, I’m new to the forum and I have a question.

      I am in the process of replacing the steering rack in my 2008 Mazda 3, and noticed an “extra” port near the top of the valve housing on the new rack (capped off with a red plastic cap). The OEM rack has a similar indentation, but it is not an open port.

      I only need the two ports on the opposite side of the rack–supply and return. I admittedly have no idea what this port is.

      Here are the links to the images of the port in question:

      I contacted my local Mazda dealership’s parts department, and they had no idea what it was. They were only more interested in selling me the remanufactured rack they offer (for $200 more than the rack I already have). The guy I spoke with did give me the OEM part numbers to have Advance Auto (where I bought the rack) cross reference them with models in their system, but nothing came up when running a search.

      The tech I spoke with at A1 Cardone initially thought it may have been an EVO sensor. That is something which, to my knowledge, does not exist on this particular model. He was going to pass the question along to a product development engineer and get back with me later on. Hopefully, he will have a solution…

      I’ve posted this same question on a few Mazda forums, and have yet to hear back from anyone. Anyone here have any thoughts?

        It looks like a port plug is missing.Could be a defect.

          I say just put red plug back in and tape it over. Doesn’t look like it’s for anything functional.

            I thought about it, but given the location of the rack when installed (PITA), I’d rather make sure everything is as it should be now.
