Why is my power steering stiff on my 2001 Lincoln town car?

Stiff Power Steering in your 2001 Lincoln Town Car could be due to low power steering fluid, a worn-out pump, or a malfunctioning steering rack. Additionally, it could be caused by a blockage in the power steering system or issues with the serpentine belt that drives the pump. Checking the fluid level and examining the pump and belt for wear can help identify the problem. If you're unsure, it's best to consult a professional mechanic for a thorough diagnosis.
