A mechanic told me he'd have to change power Sterring resevoir because of a hairline crack($170). I drove to Home Depot and got a hose clamp and solved the never found crack by squeezing the tubing closed
I replaced power steering pump high pressure & low pressure hose car is still whining a little while driving & whining gets really loud gets really loud when I make a left or right turn ..The other really short hose that's connected to the radiator is leaking now,,what is it called
Same as everyone else. Slow steering Fluid leak. The main culprit was the high-pressure hose. Also replaced one of the non-pressurizes hoses up top since it showed some cracks. Total cost about $500-$600.
I see this is fairly common. I trimmed the leaking hoses at the tank and will be looking in to the under car issues shortly. I am going to see if I can have a hose maker make new ones for me to replace the factory hoses. If you have enough miles for this to be a problem then check the hose going to the power brake booster. Mine bacame brittle and cracked open.
