158K miles. Recent slow leak, loss of power steering (PSA) assist. I replaced OEM pump w a remanu O'Reilly's pump, new rings and seals. Remanu has v loud whine and slightly restored PSA. After 400mi, my mech replaced oem rack N pinion w O'Reillyremanu. Loud whine and reduced PSA continue. Plus occasional foam in reservoir after 10+ mi drives. I'm currently having remanu (Loud whiny) pump w a used OEM pump, installing new O'Reilly Hi-pressure line, new seals, new pressure switch, fluid by local mech w 15y experience. Orig OEM return line remains in place. Stay tuned.
FYI: was told load whine is common w non-OEM pumps.
Anybody know if this is true? Or can offer tips. Thx
