It doesn't make any sound when I turn the wheel, its just extremely heavy and doesn't turn totally back to the center when you leave it. If you take your hands off it the car keeps turning.
No, the light didn't gone out. When I first used the car after the servo motor was installed the lights were off for some minutes and then came back on.
Regarding the steering fluid level, to be honest I have no idea, I'm gonna pass by the shop tomorrow and ask the guys about this, and post here later.
Thanks for trying to help guys really appreciate it.
