Would anyone happen to have the part number for the repair kit for the steering control valve?
Thanks.

B5AZ-3A650-A  If You do a google search there are some available fro several sources. Not much to the Kit. Couple of Seals.. If You don't feel Confident in doing it yourself try Lares Corp. They may have an Exchange One or rebuild and return Yours.I did send mine out to be rebuilt and once You take it off your Car its out of Service until returned. The hardest part may be getting the Stud to pop out of the Steering Arm when You take the Nut off. Shop Manual tells You how to get the Control Valve off.
