Product Overview

The 4773303 is a genuine TRW steering gear designed for the specified Ford, International, Mack, Volvo, and Freightliner truck applications. It converts steering wheel rotation into the mechanical movement needed to turn the wheels.

Product Features

The 4773303 steering gear is manufactured to TRW factory specifications for transferring steering wheel input into wheel-turning motion.

  • Converts rotational movement from the steering wheel into the side-to-side mechanical motion used to turn the vehicle’s wheels.
  • Serves as a central mechanical component in the steering system, connecting the driver’s steering input with directional wheel movement.
  • Provides mechanical advantage through the steering gear mechanism, supplying the leverage needed to carry out the steering action.
  • Reduces the effort required for low-speed steering, where the supplied description identifies increased demand on the steering mechanism.
  • Supports controlled wheel response to steering input, allowing the vehicle’s direction to be adjusted through the steering system.
