How do fellas,
A bad power steering pump has many symptoms. One tall tale sign of a bad pump is squealing sound upon start-up, and while turning, particularly during tight corners or while driving slowly. Another symptom is stiff steering in cold weather or while turning at low speeds. Finally, be on the lookout for a bit of slippage while turning the wheel.
Once you've diagnosed your power steering pump as kaput, it's time to embark on the exciting replacement procedure!
1) Disconnect the negative battery cable.
2) Remove the coolant recovery reservoir and bracket.
3) Unfasten the ECM retaining nuts, then remove the cover.
4) Remove the serpentine belt from the pulleys by loosening the automatic belt tensioner.
5) Disconnect the inlet and outlet hoses from the pump.
6) Unfasten the pump mounting bolts, then remove the pump and reservoir.
7) Using a suitable prybar, remove the retaining clips from the reservoir, then separate the reservoir from the pump.
8) Remove the pump pulley using a power steering pump pulley removing tool J-25034-B or equivalent pulley pullers.
