Squealing when turning
When I turning the wheel squealing grinding noise.
Is that the power steering? What can I do to fix it?
Yes. Begin by checking power steering fluid. A power steering pump low on fluid has a distinctive sound, s sort of 'growl;. and I cheched first to make sure that the 2011 Impala does not have electronic p/s, it does not. If the fluid is good, may be the serpentine belt loose, especially when you hear a squeal. Merry Christmas, ~~David
Even if you engine does not look exactly like this, the p/s reservoir will look like this an image of a steering wheel
