How Much Does a Power Steering Pressure Hose Replacement Cost?
Power Steering Pressure Hose Replacement Service and Cost
Hydraulic power steering systems need at least two power steering hoses. One for high pressure, and the other for low pressure. These hoses deliver fluid to and from the power steering pump and power steering gear, allowing the steering wheel to turn with greater ease.
Power steering pumps create hydraulic pressure, and the hoses transfer the pressure to the steering gear, where it will be used to assist the driver turning the wheels, and the other hose will return the used fluid to be pressurized. This process happens continuously, and the pressurized line from the power steering pump to the power steering gear is under heavy stress every time the vehicle is driven.
Power steering component failure almost always means a leak, but the amount of leaking fluid will determine if the vehicle can be driven. Also, if failure of the pulley or accessory belt occurs, the vehicle may be stranded if the belt also drives other accessories. Small leaks will not prevent the vehicle from driving, but when fluid cannot be added quickly enough to keep the pump full, a tow truck is recommended to avoid damaging the fuel pump and steering gear.
For most vehicles, the power steering system will last well over 100,000 miles before any failures occur. Mechanical failures and leaks in the power steering system are considered usually avoidable if maintenance has been performed according to the manufacturer service intervals. Keeping the power steering fluid fresh, and the system free of contaminants is the key to ensuring long power steering system life. As any system that carries high pressure will, the system will eventually fail from normal wear and tear, but this should be well into the serviceable life of the vehicle.
Power Steering Pressure Hose Replacement Repair Information
Since most power steering issues will generate the same symptoms, it would be difficult to diagnose only one part, without understanding the condition of the whole system. When symptoms emerge, the power steering fluid is inspected, and topped off, and the condition, and tension of the power steering pump belt is noted. The system may need to be bled of air prior to diagnosis. Any leaks will become very obvious at that time, and mechanical failure of the power steering pump will be evident from noise, or a pressure gauge inserted into the power steering line. At that time, if no other issues are found, the steering rack or steering gearbox will be suspected of failure. Any dust boots and seals will be inspected for leaks. The rack and pinion gear set will be inspected for sounds typical of mechanical failure. This systematic approach will lead a technician to a diagnosis.
Replacing the power steering hoses differs from rack and pinion style steering gears to steering gearbox type, only in that the location is different. Steering rack hose connections will be underneath the vehicle, near the axle, and steering gearboxes are typically on the frame rail, and near the front of the wheel-well. Otherwise, the procedure is completely the same. Hoses are simply disconnected from both ends, one on the steering gear, and one on the power steering pump. Replacement is as simple as screwing the new hoses on, and filling and bleeding the power steering fluid. However, many vehicles may necessitate removal of several components to access the power steering hoses on the power steering pump, or may have a complicated bleeding process. Vehicles that use a hydraulic hydro boost system that uses the power steering fluid pump will have at least two power steering lines, and most likely four. The added components will also add a degree of difficulty if they have specific filling and bleeding instructions.
We recommend against any product that claims to stop leaks in the power steering system. These products contain sealants that will become contaminants as they cure in the power steering fluid, and build up inside components that are only designed for fluid. This can lead to failing power steering pumps and steering gears, as well as the original leak.
Power steering components are subject to high pressure, high heat, and high speeds. Selecting parts that are built to meet or exceed OEM standards will help ensure the longevity of the power steering hydraulic system. Inferior parts tend to lead to repeated replacement.
Power steering hose replacement can be done as a DIY repair as long as the fluid is collected properly, and, in many cases, a small torque wrench is available. Many power steering pumps are sealed by a brass crush washer, that must be tightened to the proper specification to seal. Using a torque wrench will prevent the banjo bolt, and the power steering pump outlet from being stripped. Power steering hoses seem to be tucked away into small areas very often, and may be difficult to extract. In fact, some vehicles require removal of the power steering pump before the hose is removed. In these situations, it is better to trust a certified technician with the repair.
