I just have bought a Toyota Yaris of 2007 and observe two things. There is a squeaking sound from right front when driving over 60-70 km/h. Another is when turning wheels right or left completely I hear creak (like a rubber by rubber) from both front wheels. Visually everything looks fine.
What can cause such noise and what can it cost me?
So, the steering creak problem is solved. These were rubber hobs (the big rubber pieces where shock dampers connect to the body). We just put some oil there and after a few kilometers the sound disappeared.
Still looking for the solution of the other problem.
