because the fluid is cold and hasnt fully began to flow through the system. same as the oil, it settles at the lowest point and it takes a couple seconds for the pump to bring it up to speed......as they say
Bad steering rack mostly found on GM vehicles exhibits itself usually at the first start in the morning Weak power steering pump Belt slipping or glazed
First thing to check is the fluid in your power steering pump. If the fluid level gets low, your pump will squeal or quit working altogether. Once the pump gets overheated (due to low oil level) it will most likely need to be repaired or replaced depending on the vehicle. There are several variables to consider such as serpentine belt, rack-and-pinion or steering box condition, but the first thing mentioned is where you should start.
The hydraulic seals in your power steering will be eaten away by engine oil. Your power steering will start to leek and eventually, it will not work at all.
Have you tried tightening it ? Always start with the free simple things first, it usually is one of them.
U first after taking off the power steering pump make sure all fluids are out of the lines then put new 1 on the add fluids while vehicle is off then leave the lid off the pump start vehicle an then make full turns an hold after each full turn an keep doin that an all the air will come out make sure u do it till there's nomore bubbles in the fluid an that's purging
Power steering pump should be replaced.
Ensure power steering fluid is to full mark. Start engine. Turn wheels slowly all the way the right until they hit the stop and hold for a minute, then slowly turn all the way to the left and hold for about a minute. You may need to repeat a couple of times. This should bleed the air from the system. I don't know of any vehicle which has a bleeder valve for the power steering reservoir or power steering system.
unbolt the power steering line from the power steering pump. have another person inside the vehicle to start the engine. open the power steering reservoir. have the person inside turn the steering wheel back and fourth, left to right as you pour power steering fluid into the reservoir until it pours out clean from the unbolted line. make sure the loose line is seated into a pan or bucket to catch the fluid or you will have a mess. that should unclog the pump and the line. if the pump still doesn't work after you put the line back on, then you probably have a bad pump. replace the pump. hope this helps.
The power steering fluid is leaking because somewhere in the power steering system there is a leak. It is possible one of the seals on the steering rack has worn out. That would be a good place to start. It could also be coming from a leaky seal on the power steering pump or from one of the lines.
it seems that the safe and easy procedure for changing out the power steering fluid, assuming there are no other issues, is to(with engine off) remove the old fluid from the reservoir with a siphon bulb and refill with fresh. start vehicle cycle the steering wheel back and forth for a minute or two. kill engine and repeat until your heart is content(more or less).
Fill your power steering fluid. When you get low it will start to whine. Do this as quickly as possible, because replacing a power steering pump is not fun.
Could be that your low on power steering fluid. When it's cold, the fluid is more viscus, but once it warms up and thins out there isn't enough.
