Power Steering Hose Replacement

power steering hose replacement, power steering hoseNo one likes a leaky car or a 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! For more information on how to identify a power steering leak and find out where the leak is coming from, try reading our article on power steering leaks!

If you’ve got a leak in a power steering hose, the only option is a power steering hose replacement.  There are a few different ways a power steering hose can leak:

  1. High-pressure line o-ring leak
  2. Crimp Leak
  3. Low-pressure hose fluid leak
  4. Low-pressure hose air leak

The high-pressure lines in your power steering system can carry up to 1500 PSI so it’s not surprising if they start leaking after some use.  One of the most common high-pressure line leaks is where the line connects to the power steering pump and rack and pinion. These connections use small o-rings to seal the connection so, over time, these o-rings can become hard and brittle which leads to a leak.  Replacing o-rings is as easy as removing the line and replacing the o-ring at the fitting.

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 as 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.

After the power steering fluid exits your steering rack or gear the fluid is at a much lower pressure.  This low-pressure fluid flows through a series of hard and soft lines and usually through a power steering cooler before it travels back to the fluid reservoir.  Fluid leaks in the low-pressure lines are much slower due to the low pressure, but still should be sealed as they will leak even when your car isn’t running. In this case, replacing the hose is the best way to stop the leak.

Finally, an air leak into your power steering system from the hose that runs from your fluid reservoir to your steering pump can cause a lot of noise in your system.  Air trapped in the power steering fluid will make a power steering pump noise so sealing this type of leak is important for your sanity and for the longevity of your power steering pump.  Replacing this line and any o-ring at the power steering pump is the best way to seal this type of power steering leak.

  1. One of my lines busted in caddy deville no powe steer fluid will even staying there no hold leak will either. It’s coming from driver side under steer wheel. Will I have to replace whole line its pressure line.

    1. Daphne,

      Yes, based on your description, it does sound like the line will need to be replaced. Based on how quickly you are losing fluid, you wouldn’t have use of your power steering until the line is replaced.

      Thank you!


  2. My 06 Chevy Trailblazer will not hold any fluid. It leaks on the drivers side
    Which hose should I buy for replacement?

    1. Miyana-

      Thank you for asking about your Chevy Trailblazer. Based on your description, your best bet would be to have the vehicle inspected by a certified ASE mechanic. That way, they can pin-point the location of the leak, and replace the necessary hose.

      Thank you!


  3. I have fluid coming from the gear in my 1500 1999 Dodge ram 3.9 liter 6 cylinder is there is there anything I can do before I buy the gear replace ment

    1. Calvin-

      Thank you for asking about your Dodge Ram 1500. The BlueDevil Power Steering Stop Leak would be able to treat a leak that is seeping or lightly dripping from the gear box. You would add 1/3 of the bottle into your power steering reservoir, and should expect to start seeing results after approximately 100-200 miles of driving.

      Thank you!
