Power steering pump being removed for replacement or repair

Occurring defects in the steering hydraulic pump:

  • - wear of the pump bearings (constant noise from the pump);
  • - the flow and safety valve do not work due to contamination (there is increased pressure in the system);
  • - fluid leak through technological holes in the pump housing (plugs squeezed out);
  • - fluid leak from under the pump covers.

If the steering wheel turns hard in both directions, then the pump is faulty.
