I've noticed lately that it makes a grinding noise when turning sharply. It's especially noticeable when the AC is running. Car has 135,600 miles on it. My Mother owned it since new and I bought it from her to use as my commute car. Had the CV axles replaced about 3 months ago. Getting the suspension refreshed tomorrow as that was never done. Any ideas what could be causing the grinding noise? Wondering if it could be the power steering pump.
