to bleed power steering, with front wheels off ground slightly with front wheels pointing straight ahead.engine off. remove power steering filler cap.add power steering until fluid level stop dropping,wait couple minutes and wait, add fluid until level stay at full cold mark on power steering cap dip stick. dont over fill.when fluid level stop dropping, start vechicle,let it idle few minutes. see if fluid level drop if so add more fluid full cold mark.then turn steering all the way to left and right with out hitting a stop.turn steering wheel several times, then turn front wheels pointing forward check power steering fluid level.if power steering fluid level stop dropping air should be out of system, if steering turning wheel dont turn smoothly and power steering fluid look light tan color air getting in the system.check all power steering lines to rack and power steering pump for leaks.be sure you replaced all the power steering lines with new o rings if not you will get a leak.if you find a leak, you need to fix the leak and bleed system again.dont drive vechicle if your steering dont feel right,have vechicle towed to a garage.
with power-steering it could be one of three problems. 1- power steering pump could be going out ( normally with the pump the car will whine but will not normally leak and still hold fluid) 2- a leak in your power steering lines ( and can normally be resolved with new lines or sometimes you may be able to bypass and clamp the leak on the line) 3- you may have busted the O rings in your powersteering pump and that will actually cause the pump to leak
hint- alot of people will tell you that you may also use transmission fluid for power-steering this is true you can its that same thing as power-steering fluid just a different color (but dont put power-steering fluid in a transmission, but at the same time if you plan on replacing the pump i would use transmission fluid due to it being cheaper but it will cause the O rings in the power-steering pump to go out quicker to cause a worse leak) so i would recommend to locate the leak first before using trans fluid due to if its in a line you wont have to replace the pump but if its already the pump this is the cheapest fix until repaired
You've got a power steering fluid leak. The noise is the power steering pump low on fluid. I would put some Lucas Power Steering treatment in the system and refill the fluid. It won't fix the leak forever, but it will recondition the seals and rubber and buy you a lot of time.
if there is a leaking seal in the power steering rack and pinion or in the hydraulic pump, a power steering stop leak may swell the seal enough to stop the leak. if there is still a leak, it is likely a damaged / corroded line or fluid cooler. next time you need to top up your fluid, i recommend Lucas brand power steering stop leak / treatment. after a couple top ups it will stop the leak it if is a rubber seal problem. good luck!
Have a look at the power steering fluid cooler it is just in front of the radiator behind the front bumper. The coolers corrode and leak. Also the seals can go, check for fluid leaking out of the boots at the track rods.Try this procedure :---1)Trace the source of the leak. Use a mirror on an extended handle to follow the puddle of fluid on your garage floor to the power steering system. Look on the hoses and gaskets to find from where the fluid could be leaking.2) Add power steering stop leak additive to your power steering fluid. Lucas Power Steering Stop Additive is 100 percent guaranteed to stop seal leaks. In older cars, the seals shrink, causing leaks. The stop leak makes the seals swell to their original size.3) Use gasket sealant if the gaskets are old and leaking. Sealant, such as Permatex, is resistant to engine fluids, and will help repair a leaky gasket.4) Replace the gasket, if the gasket sealant does not work.

The power steering leak is creating bubbles in your power steering pump which gets strained more when turning, which causes it to be louder when turning. If you know where your leak is, then fix that, then try to bleed your ps system by filling up with the cap off the resevoir and turning the steering wheel max left to max left with trans fluid. if the noise is still there then your ps pump needs to be replaced along with the ps vsv located on the side of the pump.
Find the leak and repair it...It is a sealed system, if you are adding large amounts of power steering fluid, it is leaking out somewhere. Hoses, reservoir, steering box, power steering pump are places to check. You should only have to add minimal fluid to the system for the entire year.
The immediate squeal you hear is most probably the unit is out of fluid or has leaked onto the serpentine belt and causing it to slip.
Fix the leak and check your serpentine belt for wear.
