Mobile Power Steering Hose Replacement at Home or Office

No one likes a leaky or noisy car. Power steering systems can quickly cause both of those problems in your car so it's important to get things fixed up as quickly as possible. Power steering leaks can come from a variety of places in your system. Many of these leaks can be sealed without removing any components. If you've got a leak in a power steering hose, the only option is a power steering hose replacement. One of the other common leak points that requires power steering hose replacement is a leak at the crimp point in the high-pressure hose. Your power steering pump is mounted to your motor which moves with your revs, while your steering rack or gear is mounted to the frame of your vehicle which does not move. To allow for this movement, a section of the high-pressure line in your power steering system needs to be a flexible rubber hose. The point where this rubber hose gets crimped to a hard line endures lots of stress which can cause failure of the soft hose. If you've got this type of leak, the only solution is to replace that line.

What is Power Steering Hose Replacement?

In your car's power steering system, the power steering pump forces high-pressure fluid from the reservoir to the steering gear, or rack and pinion. The fluid provides hydraulic assist for your steering system in the rack and pinion, so long as the fluid flow is proper. A hose carries the fluid from the reservoir to the steering gear, and that the hose is known as the power steering pressure hose. When a power steering pressure hose develops any amount of leak, it will need to be replaced.

How is Power Steering Hose Replacement Done?

  1. Open the hood and locate the power steering pump and reservoir.
  2. Check power steering fluid level.
  3. Locate the power steering pressure and return hoses.
  4. Inspect power steering hoses for leaks.
  5. Place a drain pan under the pressure hose connection at the steering rack or gearbox.
  6. Using a flare nut wrench, loosen and remove the pressure hose fittings from the steering rack/gearbox and the power steering pump.
  7. Install the new power steering pressure hose, making sure to route it the same as the old hose.
  8. Fill the power steering reservoir with the manufacturer's recommended power steering fluid.
  9. Start the engine to circulate the power steering fluid. Stop the engine and refill the reservoir.
  10. Start the engine and turn the steering wheel from left to right. Check the steering hoses and rest of the power steering system for any leaks.
  11. Turn off the engine and check the power steering fluid level.
  12. Road test to verify the repair.


When the power steering hoses are replaced, the entire power steering system should be inspected. If the pressure hose has deteriorated from the inside, the rubber return hose should be replaced as well and the system should be flushed.

Symptoms That Indicate You Need A Power Steering Hose Replacement

  • Red or brown oily substance on the ground under the engine bay
