Detailed Description

This PWR steering gear, part number 61-5531, is built for Ford F-100, F-150, F-250, and F-350 truck applications where a power-assisted steering gear is required. It is a direct-fit replacement that matches the listed spline counts, shaft diameters, and port thread sizes for proper integration with the steering system. This part cross-references Atlantic Automotive Engineering 7505N for the same application.

Compatible With 1970-1979 Ford F-100, 1975-1979 Ford F-150, 1970-1979 Ford F-250, and 1970-1979 Ford F-350. It also fits 1968-1969 Ford F-100, 1968-1969 Ford F-250, and 1968-1969 Ford F-350 with Ford gear applications. The PWR 61-5531 is a practical replacement for restoring steering response in classic Ford trucks.

What It Helps Address

  • Excessive steering play or looseness
  • Hard steering effort in power-assisted systems
  • Leaking or noisy steering gear operation
  • Worn internal steering gear function
  • Incorrect fitment from mismatched spline or port dimensions

Installation Notes and Tips

Verify the input and output spline counts, shaft diameters, and port thread sizes before installation. Confirm vehicle application by year, model, and whether the 1968-1969 trucks use Ford gear configuration. After installation, inspect the hydraulic connections and bleed the power steering system according to service procedures.

Quality Assurance

PWR states that its pumps, racks, and gears are tested for leaks, pressure, noise, and function, and this steering gear is USA engineering approved.
