Chevy Impala leaking steering fluid and steering wheel stiff.

Sounds like the high pressure power steering hose is leaking. Check it out and if so replace it along with the low pressure return line. If the lines are not leaking then the power steering pump could be the problem.

Have you checked the level of the power steering fluid if it is low it can cause a noise similar to what you described. The power steering pump could be starting to fail and making the noise. I would suggest checking the power steering fluid level and if low, they make some fluid that has power steering fluid conditioner, supposed to help extend the life of the power steering pump, if it is low you need to follow the lines from the pump and see if you can find a leak anywhere. also I would take notice of the color of the power steering fluid, if not too much trouble maybe take a picture of the fluid and upload it here, the fluid can break down and need to be replaced.

The power steering pump is bad! God-Bless! or the rack and pinion leaks, check the pump first. the pump whines if low on fluid or bad.

sounds like power steering pump is shot.If it ran out of fluid and there is a leak somewhere else,it will burn the pump up.

steering rack end sounds like its leaking

you just need to check your steering pipes and hoses for any leaks. just replace them if a leak is found. if your reservoir itself has a leak, then your only best bet is to replace the whole ting ..

Sounds like a bad steering rack & pinion assembly... is it only bad in one direction or both...?
If both then it's the rack assembly... Hope this helps...;-)

You are either low on fluid or have a return line leaking. Pull the cap off the reservoir and check the level and also if there are bubbles in the fluid. Bubbles indicate a leak in return line or seal.

What you hae to do is check if the reservoir is leaking first if okthen it is either the piping or the steering pump. It is a process of elimination, you may need to clean the area first to discover where the leak is or work back from the point it is leaking on the belt. Until you identify where the leak is coming from it will be dificult to repair unless you just start to replace the pump and reservoir any way.
