Power steering hose keeps breaking, even when replaced by high pressure hoses. Replacing rack and pinion does not help either.

Just a guess, is it possible to have the hoses in the wrong port?
Not sure if that would cause this

No, the power steering is entirely a separate and sealed system, wholly external to the engine. The power steering pump pushes the fluid through a high pressure hose into the rack and pinion-the steering gear mounted below and behind the engine-and holds pressure within the rack that enables power assisted steering. At the same end where the power steering fluid hose enters the gear will be a fitting for a return line back to the fluid reservoir. These two hoses are usually routed close together at least part of the way, some may even be held together with brackets. Leaks could develop at the pump, the fluid reservoir, or the two hoses to and from the rack and pinion, or the seals inside the rack and pinion may have failed. You should be able to find the leak-it will only leak to the outside-to check the rack and pinion for leaks, right where your tie rods come out of the gear and go to the wheels for steering, will be a small rubber boot encasing the tie rod and the end of the rack assembly-on both ends is a boot and a tie rod-peel back the rubber boot from the gear ass\'y, it should be dry. If a lot of fluid, the seals in the rack and pinion are gone. It will have to be replaced.
Hopefully you will find a leaking hose or fractured reservoir, but keep looking, air flow may be blowing the leaking fluid back and under the car. Good luck, hope it\'s not the rack and pinion.

Disconnect battery ground cable.
Remove engine Air Cleaner (ACL) .
Disconnect electrical connector in back of engine cooling fan motor.
Remove radiator fan shroud.
Disconnect constant control relay module harness from headlamp harness and place constant control relay module on top of engine to provide accessibility to power steering lines.
Remove wiring harness guide retaining screws and position guide aside.
Remove screw at power steering hose bracket.
Remove anti-rattle clip.
Remove plastic strap retaining tubes to power rack and pinion steering gear.
Remove power steering pressure hose at power steering pump.
Remove power steering pressure hose at power rack and pinion steering gear.
Remove power steering pressure hose from vehicle.
Reverse procedure to install new hose.
Fill and bleed power steering system.

RETURN TURN LINE GOES TO THE LEFT OF RACK PINION AND HIGH PRESSURE HOSE GOES TO THE RIGHT OF RACK PINION.LOOKING AT POWER STEERING PUMP HIGH PRESSURE HOSE THICK HOSE SCREWS INTO POWER STEERING PUMP.WHILE LOW PRESSURE HOSE HAS A HOSE WITH A CLAMP THE LOW PRESSURE HOSE HOOKS TO TOP OF POWER STEERING PUMP.LOW PRESSURE DONT SCREW INTO POWER STEERING PUMP IT IS HELD IN PLACE BY A HOSE SMALL CLAMP.

There are only two that go from pump to the rack and pinion. The high pressure hose, which has partial metal line with high pressure hose crimped to it and the return line which is mostly just rubber hose with some regular clamps to hold it to the metal part coming out of the rack and pinion.

POWER STEERING PUMP OR HOSE HAS NO SET TIME OR MILEAGE TO FAIL WHEN THEY WEAR OUT THEY WILL FAIL ANY TIME.I WOULD HAVE POWER STEERING HOSE REPLACE FIRST.IF YOUR STEERING WAS NORMALWORKING GOOD BEFORE HOSE RUPTURE NO NOISES OR HARD STEERING.REPLACE POWER STEERING HOSE.BECAUSE POWER STEERING PUMP AND RACK PINION UNIT GOING TO COST RIGHT MUCH.ALSO BY IT BEING A IMPORT.

Possibly, but more likely a break in the high pressure hose that runs from the power steering pump to the rack and pinion assembly.

ALL YOU NEED IS A FLARE NUT WRENCH.THE OTHER END OF HIGH PRESSURE POWER STEERING HOSE GOES TO THE RACK AND PINION STEERING GEAR.

when it comes to the power steering hose I would say just do it yourself. As for the rack and pinion it will probably cost you quite a few hours of labor. anywhere from 5-9. Its up to you!

from the pump to the steering box/rack &pinion there is one high pressure line.
