I have 1994 Toyota Corolla and milage is 137000. It gives vibration sound while turning right from Left front wheel. I went to mechanic and he replaced the ball bearing. Still it makes that sound. What could be the reason. Please suggest. It has one more issue. While turning to left it makes the sound like two metal plates are sliding on each other from right back wheel. It also makes thumping sound from right back wheel while driving staright. Please let me know the reason and how much it will gona to fix all these things. I will appriciate it.
