Replace pressure and return power steering hoses on 2004 Hyundai santa Fe

if you are talking power steering system, the whine is a vibration in a problem control valve and could be in the steering valves on the rack

The difficulty will be from limited work space and incorrect spanners to do the job Otherwise it can be done by any one with some mechanical knowledge.

Not with a diagram. Clean all the hoses and the pump so that everything is easy to see. Start the engine and get someone to put a little pressure on he steering. You should be able to find the leek.

The power steering lines/hoses go to the steering rack (they go past the alternator).

Yes it can be spliced and repaired. As it is very low pressure.

Try flushing the fluid,which you should be
doing every 3 years
Add a bottle of Lubgard for power steering or
what ever the dealer has
Use the correct MFG Fluid

Eventually you will replace the pump,
when you can no longer stand the noise.

Then steering rack most likely is about to fail
from not changing the fluid and is causing stiffness
and high pressure thus the noise

Did you find an answer because mine is leaking bad!!!

Not really expensive just messy to repair. Return lines (low pressure) are much more common and they travel along the frame rail on the right side of the subframe from the power steering rack to the cooler line in front of the radiator. The high pressure line starts at the pump and travels over the top of the motor to the back side (it's a thick line with a big banjo bolt at the pump). They go too but less frequently.

If it's the return line and not the pressure line you can cut it and put some rubber hose from the parts store over the cut part with a couple clamps and that'll hold you for quite a while till you can get the line and get it installed.

The return line, done correctly, can be a bit of a bear on the ground but it's fairly quick in the air on a lift at a garage. The pressure line isn't too bad and can be undertaken by the home mechanic.

hola ! from uk excuse no understand botando?? assume you mean the hose that comes from liquido resevoir to steering rack ? this is the return pipe of liquido from rack BUT if hose is the one from pump to steering rack? this is special high pressure feed pipe which has steel tube and couplings this cannot succesfully be repaired so requires new replacment ? it is simple diy job to replace hope this helps you and good luck with repair?
