As a part of the hydraulic power steering system, it is responsible for transporting high-pressure fluid from the power steering pump to the steering rack, which assists the driver in turning the steering wheel.

Reasons to replace a power steering hose
You should replace this power steering hose when it fails, which can happen due to age, wear and tear, or physical damage. Common signs of failure that indicate the need for a replacement include: 
Fluid leaks: This is a very common issue where power steering fluid leaks from the hose or its connections. You might notice red or amber-colored fluid pooling under your vehicle.
Increased steering effort: If the hose is damaged, cracked, or clogged, it can restrict the flow of pressurized fluid. This forces the power steering pump to work harder and makes it more difficult to turn the steering wheel.
Unusual noises: A failing hose can cause air to get into the system, leading to whining, groaning, or hissing sounds when you turn the steering wheel.
Physical damage: Cracking, flaking, or bulging on the exterior of the hose are clear signs that the inner layers are failing. A bulge indicates that a complete and sudden failure is imminent. 
Risks of not replacing a faulty hose
Driving with a faulty power steering hose can lead to significant problems and serious safety risks: 
Sudden steering failure: The most dangerous risk is that the hose could burst, causing a complete and sudden loss of power steering. This is especially hazardous when driving at high speeds or during emergency maneuvers.
Damage to the power steering pump: Low fluid levels caused by a leaky hose can force the power steering pump to run dry and overheat, leading to premature and costly failure.
Other system damage: The contamination caused by a deteriorating hose can introduce rubber and metal particles into the system, potentially damaging the pump and steering gear.
Fire hazard: Power steering fluid is flammable. If a hose leaks fluid onto hot engine components, it could cause a fire.
