Detailed Product Description

WIX 57191 is engineered as a heavy-duty power steering filter for systems that need consistent fluid filtration without restricting normal steering flow. The premium cellulose media is paired with a durable spin-on housing, making it suitable for routine maintenance where clean hydraulic fluid helps protect pumps, gears, and valves. This part number is commonly cross-referenced with Baldwin BT9388 and NAPA Gold Filters 7191 for the same application.

Searches for a Ford power steering filter, International Harvester steering filter, or Navistar hydraulic steering filter often lead to this part number because it matches the application-specific dimensions and service requirements used in those systems. If you are replacing a WIX 57191 filter during scheduled maintenance, verify thread size, height, and system specifications before installation.

What It Helps Address

• Contamination in power steering fluid
• Restricted steering response caused by dirty hydraulic fluid
• Wear on pumps and steering components from fine debris
• Service issues in heavy-duty steering systems
• Leak concerns from worn or poorly sealing filter elements

Installation Notes and Tips

Confirm the filter style, 3/4-16 thread size, height, and outer diameter against the original unit before installation. Replace the filter at OEM-recommended service intervals, and inspect the steering fluid for debris or discoloration when servicing the system. For fitment-based searches, this part is associated with Ford, International Harvester, Navistar, and Sterling applications where the WIX 57191 is specified.
