What This Product Does:

• The pressure line carries high-pressure hydraulic fluid from the power-steering pump to the steering gear or rack. This enables the system to provide assist to the driver’s steering input.
• Correct hose integrity ensures fluid stays contained under pressure, the steering assist remains consistent, and no performance loss or fluid loss occurs.
• A failure here can impact steering feel, safety, and can lead to fluid loss or damage.

Symptoms & Signs You Might Need Replacement:

• Visible fluid leak: oil or power-steering fluid puddle or wet spot beneath the car, near the steering gear or hose.
  
• Hard steering or increased effort: If the hose is leaking or collapsed internally, the assist will suffer and you may find the wheel harder to turn.
  
• Whining or groaning noise when turning the steering wheel — indicates stress on the pump due to fluid loss or internal hose restriction.
  
• Hose condition: cracks, abrasions, bulges, fitting damage, especially in older vehicles or where routing is near heat/exhaust components.
  
• During service: If you’re replacing power-steering components (pump, rack, hoses) and the hose is original or aged, replacing the pressure line is wise.
  
  

Why Replacement Matters:

• Steering safety & performance: A pressure line failure can cause sudden loss of assist or fluid loss — replacing before major failure is proactive.
  
• Prevents collateral damage: A leaking hose may cause fluid contamination of other components, damage the pump, or even cause burnt rubber in the bay.
