What is the correct order to adjust a power steering box?

The correct process for adjusting a power steering box begins with input shaft preload, followed by sector shaft endplay, and finally, adjusting the poppets. The rationale behind this order is based on the functionality and interrelation of the components involved.

Starting with input shaft preload is essential because it establishes the initial tension within the steering box mechanism. This tension is critical for smooth operation, as it affects the responsiveness and overall feel of the steering. If the preload is not set correctly, it can lead to excessive play and a vague steering feel.

After adjusting the input shaft preload, the next step is to set the sector shaft endplay. This adjustment ensures that the sector shaft has the correct amount of axial freedom, which affects how well the steering box can transmit forces without binding or excessive clearance. If the endplay is too tight or too loose, it can significantly impact steering performance and life of the steering components.

Finally, adjusting the poppets is crucial for achieving the appropriate flow and pressure within the power steering system. They help regulate the fluid flow and pressure, which is necessary for the successful operation of the power assist feature. Adjusting poppets last allows for a final fine-tuning of the steering box's hydraulic system after the mechanical components have been set
