Hi I have a 1999 GS400 with 100,000 miles and it makes a noise from the front of the car when I turn either left or right also it makes noise when I go over bumps or when I turn while reversing or when I turn when I put the car on drive it also makes the same noise when I am parked in a steep drive way and I put the car in either drive or reverse. The noise is like a metal knocking, bending and cracking type of noise. My brother looked at the car and said its the rack and pinion but I think its the control arm but what do you guys think. Keep in mind the noise comes from both sides of the car the left and right when I turn.
