Must add power steering fluid every two days.

A bad seal in the rack and pinion would have caused low pressure from fluid by-passing the seal. This also would have caused noticeably increased effort to steer the vehicle. Excessively high pressure would indicate an issue between the power steering pump and the rack, and since the hoses have been replaced I would focus on the pump. PS, find a real mechanic, not a parts changer.

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.

These details will help.
Thanks.

if the rack and pinion was not leaking or causing problems. then he may of made a wrong move! if the rack was fine before, and you just lost power steering. then it is most likely the power steering pump or the lines that go from rack to the pump. good-day ! if a rack goes bad, you will get a bad steering problem or just bad steering.

If your rack and pinion steering unit is leaking power steering fluid, you most likely have blown a seal in the unit. These are gennerally non-repaiable. Replace the rack and pinion unit. Not an easy job, but an intermediate knowledge home mechanic can do it.

Hi and welcome to FixYa!

If that's the case then the oil seals of the rack and pinion should be replaced. If the seals are worn out it tends to leak and can definitely feel a loss of power. If it still leaks even after the replacement then the rack and pinion should be replaced.

There are instances that after oil seal replacement it still leaks it's because that the rack and pinion has severe damage.

Hope this helps and thank you for using FixYa! Have a good one!

a few possibilities.
Low power steering fluid. check for correct amount on pump filler measureing guage.

Loose power steering belt. check to see if the belt slips over the power steering pulley while trying to turn the steering wheel. may need an assistant.

last, but most expensive. Rack and pinion steering bar is defective and needs replacing.

No, the boot only keeps dust out of the inner tie rod joint--it is not intended to hold back fluid. The rack will have to be rebuilt with new seals. Sorry. :o(

If it is hard to turn it could be the fluid is low. If you can't turn the steering wheel go underneath the lower rack and pinion right were the steering shaft bolts to the rack and pinion there should be a round silver cap looks like a plug if that cap is missing the pinion bearings are broken and the rack and pinion are locked up replace your rack and pinion
