Guys I have the same problem, the rack is giving noises if the road is uneven. The Corolla 121 is my first car bought few months ago and the mileage is 68k; and I have no knowledge about repairing this or garages.. specially never been to Toyota Lanka yet. Also car is giving a very rough experience during driving, I can feel every bump and edge..sometimes the steering is shaking as well. I think I need to go to Toyota Lanka. Please help me with any knowledge you have. Thanks a lot.
