* Power Steering Pump: This is the most frequent culprit. Leaks can occur from the pump's seals or the pressure hose connection at the pump. Look for fluid dripping down the front of the pump itself.
* Power Steering Pressure Hose: This hose carries high-pressure fluid from the pump to the steering gear. Leaks can happen where the hose connects to the pump or the steering gear, or along the length of the hose itself (due to cracks or deterioration).
* Power Steering Return Hose: This hose carries low-pressure fluid back to the reservoir. Leaks are less common here than in the pressure hose, but they can still occur at the connections or along the hose.
* Power Steering Gear Box (Rack and Pinion or Recirculating Ball): Seals within the steering gear itself can wear out and leak. This will usually result in a leak near the steering gear box. Leaks here are less visually obvious than from hoses or the pump.
* Power Steering Reservoir: While less common, cracks or a loose cap can lead to leaks from the reservoir itself. This would be a relatively easy leak to spot.
To pinpoint the leak, carefully inspect all these areas for wetness, fluid drips, or trails of power steering fluid. A clean engine bay is helpful for this diagnosis. You might even consider using a black light; power steering fluid often fluoresces under UV light, making small leaks easier to detect. Remember safety first—power steering fluid is under pressure, especially the pressure hose.
