What is a power steering line and how does it work?

Power steering is a feature of nearly all vehicles on the road today. Without power-assisted steering, the sheer weight of your car, truck, or SUV would make steering very difficult, especially when your vehicle is standing still, or when parking. Although the automotive industry is beginning to see many late-model vehicles that feature electric-assist power steering systems, still most rely on hydraulic power. A power steering line is a tube that carries hydraulic oil (power steering fluid) through the steering system. The line is usually made of metal (typically aluminum) and rubber.


How is a a Power Steering Line Replacement done?

Access to the power steering lines on a vehicle is often a challenge. It is necessary to open up space to remove the connectors at each end and to extract the line from its path in the engine compartment. Some power steering lines are buried behind the engine and are difficult to reach. Some require that the vehicle be lifted and supported in the air, with shields or skid plates removed. In order to replace a power steering line, a mechanic will typically need to first remove any shields or other components that are in the way. Once the line is accessible, the mechanic will do the following:

  • Disconnect the power steering line at both ends by using a line wrench or by removing a retainer bolt (some require special service tools)
  • Detach any mounts connected to the line
  • Extract the line from the path upon which it is mounted
  • Snake the new line through its mounting path
  • Start the fasteners at both ends
  • Reattach any mounts connected to the line
  • Tighten all fasteners
  • Replace the lost power steering fluid and bleed the system

How do I know if a power steering line needs to be replaced?

When a power steering line goes bad, it usually causes the hydraulic fluid in the system to leak or be restricted. Though it can be difficult to see without lifting and supporting your vehicle off of the ground for access, a damaged or deteriorated power steering line might be identified by the following signs:

Power steering fluid is leaking

Cracks or severe corrosion appear in the metal section of the line

A line is collapsed or kinked -The rubber portion of the line is swollen or shows signs of cracking

Other questions customers ask

Is a power steering leak serious?
Any fluid leak can be serious if left unchecked. Power steering fluid must be present in the steering system to lubricate and cool the pump. If the fluid level is allowed to drop, the pump can run dry and fail. In that case, the serpentine belt can break and lead to a dead battery, loss of climate control, engine stalling, and overheating. More than that, though, the power steering system makes it easy to turn the steering wheel. Without sufficient fluid in the system, your ability to steer your vehicle can be significantly impaired, especially if the system fails while you are driving.
Can I repair a power steering hose?
Whether or not a power steering hose can be repaired depends on a couple of factors. Is the hose used on the high-pressure side or the low-pressure side? If the former, then the hose must be replaced if it is damaged or degraded. If it is used on the low-pressure side of the system, some repair shops might recommend a splice repair. However, this practice can be risky and is usually used for emergency situations only. If a power steering line of any type is damaged, it should be replaced.
Can you replace a power steering hose yourself?
The power steering system is a critical component of the safety of your vehicle. Without it, your steering wheel would be extremely difficult to turn, especially when moving slowly, or not at all. This can be dangerous if the system fails when you are turning through an intersection or trying to avoid a crash. For that reason, although some power steering lines are simpler to access than others, the job of replacing a line should be left to a qualified technician.
