Work car, 2004 chevy classic(105,000 miles), is making a very noticable sound(like chattering grinding sound) when you turn left with brakes applied at slower speeds. Not noticable when going say around a left hand curve at speed(no breaks applied). Sounds and feels like front drivers side. I took wheel off today. Nothing feels loose. I replaced front passenger side wheel bearing assembly and put new rotors and pads on front about 6,000 miles ago. Any ideas? CV joint? Second question-Taking time to check tire pressures and all fluids and notice power steering fluid is at bottom of stick. Check owners manual and calls for GM part No. U.S. 89021186. Any ideas what a good crossrefernce brand of power steering fluid is that I could use? Thanks-SHON
