Power steering fluid leak

A puddle or low fluid level usually traces back to a leaking hose, pump seal, or the steering rack itself. Fixing the leak matters more than just refilling fluid.

Symptoms

  • Reddish or light brown puddle under the front of the car
  • Power steering fluid reservoir keeps needing refills
  • Whining noise when turning that gets worse over time

Likely causes

  • CommonLeaking power steering hose or fittingHoses and their connections can crack or loosen with age and vibration.
  • CommonLeaking pump shaft sealThe seal where the pump shaft spins can wear out and weep fluid.
  • PossibleLeaking steering rack sealRack seals can leak, especially on higher-mileage vehicles.

What to do

  1. Check the fluid reservoir level and note how quickly it drops.
  2. Look under the car for fresh fluid on the ground, then trace upward to find the source: hoses, pump, or rack.
  3. Wipe down suspected areas and drive briefly, then recheck for fresh wetness to pinpoint the leak.
  4. Top off fluid temporarily to keep the system running until repaired, but don't ignore a confirmed leak.
  5. Have a mechanic replace the specific leaking hose, seal, or component rather than just topping off fluid repeatedly.
