2003 Camry 4 cyl just blew off the front low pressure power steering hose and caused a leak in another hose at the rear of engine. At my age, I can't work on cars as much so I took it to a NAPA authorized repair shop because of the warranty provided. The service manager indicated the PUMP must have allowed excess high pressure into the low pressure lines. It occurred at low speed while turning around in a parking lot. $327 later and I am very curious how this happens. Any comments are appreciated.

The only hoses that should be under high pressure is the hose from the power steering pump to the rack. Anything after the rack is still under some pressure, but it is not enough to make any hose burst from it.



I don't know how a hose can burst from a power steering pump. The common issues with any car is the high pressure hose wearing out or just wear-tear with the power steering rubber hose that can crack under age/heat. The return line where it goes to the passenger rail lower part can sometimes wear out and leak...but never heard it where it burst.
