Doosan Daewoo Steering Column Assembly A40151385: Steel Universal Joint Steering Shaft for D50S D60S D70S

The Doosan Daewoo A40151385 is a complete steering column assembly with steel universal joint steering shaft for D50S, D60S, and D70S series diesel forklifts. This assembly transfers rotational input from the steering wheel through the U-joint shaft to the orbitrol steering unit, providing the mechanical linkage between operator controls and the hydraulic steering system. At 15.0 kg with an 80x30x25 cm package, this is a substantial steel assembly built for heavy-duty industrial steering loads.

As a Doosan Daewoo branded OEM component, this steering column matches the factory mounting flange pattern, spline count, and shaft length for direct bolt-on replacement. The universal joint shaft accommodates the angular offset between the steering column tube and the orbitrol input shaft, maintaining smooth torque transfer throughout the full steering range without binding. Common failure includes U-joint cross shaft wear causing steering free play, spline stripping from loose mounting bolts, and column bearing failure producing a rough or notchy steering feel.
