What maintenance is required for a hydraulic power steering system?

Hydraulic power steering systems rely on a specific type of fluid to operate effectively, and regular fluid checks are essential to ensure that the system remains functional and does not experience issues such as steering stiffness or failure. Checking the fluid levels helps identify any leaks or degradation of the fluid, which can occur over time due to heat and contaminants. Maintaining the proper fluid level ensures adequate hydraulic pressure, which is critical for the smooth operation of the steering system.

In contrast, while replacing the steering pump can be necessary if it fails, it is not a routine maintenance task. An annual power steering alignment is not a standard requirement; typically, alignments are done when specific issues arise, such as uneven tire wear or steering that pulls to one side. Checking tire pressure, although important for overall vehicle safety and performance, does not constitute maintenance specific to the hydraulic power steering system itself. Hence, routine fluid checks are the foundation of proper maintenance for this type of steering system.
