Ive searched and searched and cant come up with the info i need. I resently re-built the power steering pump on my 80 and have a persistent gear noise after reinstallation. Ive re-seated the pump, removed,inspected and retourqed the gear and still have noise. My question is what damage am i looking at by running the truck with this minor noise.... and if i dont need to run it, what is the part number for the drive gear?
