Power steering pump: frequent breakdowns and replacement costs

1337 Views

The power steering pump – also called the servo pump – is a central element of the power steering system and plays a major role in ensuring that the steering force is supported when driving. A distinction is made between mechanical (by means of a V-belt) and electro-hydraulic steering pumps. Age-related wear and leaks in the system can cause the pump to no longer function correctly. Find out more about the typical symptoms, and the costs involved in the following guide.

Symptoms / signs of a defective or leaking power steering pump

Symptoms / signs of a defective or leaking power steering pump

  • Sluggish steering / steering only possible with increased effort
  • Squeaking when steering or grinding or grinding noises can be heard
  • Foam in the oil expansion tank
  • Fault code – P0553

What could a defective power steering pump be confused with?

With mechanically powered power steering pumps, limited steering assistance can also be caused by problems with the alternator V-ribbed belt. For example, the belt may be insufficiently tightened or broken and therefore does not move the pump correctly. In addition, many symptoms can also be caused by a defective steering gear. Therefore, a precise diagnosis must first be carried out. Among other things, the pump pressure and the flow rate must be checked.

Can you drive with a defective steering pump?

A complete failure of the pump poses a safety risk, as steering then becomes unusually difficult. Especially cars with hydraulic pumps are then hard to steer. You should consult a specialist workshop as soon as possible at the first signs that the steering has changed, become difficult, or you hear unusual noises.

Repair or replacement

Repair or replacement

If, for example, only the bearing is defective, this can be replaced separately. However, if the defect is somewhere else, the entire pump usually needs to be replaced. If you own a 2007 Honda, you can find the right 2007 Honda Accord power steering pump for your vehicle. Used parts can be a sensible option for mechanical steering pumps. In addition, it may make sense to have a refurbished/reconditioned pump installed. With hydraulic pumps, the cause of the problem is often a defect in the control unit. This can also often be repaired so that you won't have to replace the entire pump.

Costs for changing the power steering pump

The material costs vary depending on the type of pump, the vehicle model and the spare part manufacturer. The power steering pump cost usually starts at around £70, however, it is often not the pump itself that is defective, but the control unit, which can often be repaired by specialised companies. In addition, there are the costs for the new servo oil of about £10 to £20 per litre. If you are not sure which one to choose, take a look at what power steering fluid do i need to help you decide which is best for you. Depending on the vehicle, you’ll need between one and two litres.
