bushings |
|
knuckles |

The right front wheel of your front-wheel drive car drops into a pothole and the left front wheel doesn't lose contact with the road. Which of the following is true?
your car has an independent front suspension |
|
your car has a rigid axle rear suspension |
|
your car has an independent rear suspension |
|
your car has a rigid axle front suspension |
An independent suspension allows the wheels on either side of an axle to move independently from each other. The fact that the left front wheel didn't move up in response to the right front wheel moving down is evidence of this.

The fuel injectors are fed fuel by the:
fuel return line |
|
powertrain control module |
|
electric fuel pump |
|
fuel pressure regulator |
The electric fuel pump feeds pressurized fuel through a fuel filter to the fuel injectors via the fuel rail manifold. The fuel rail contains the fuel pressure regulator which ensures that the fuel injectors receive fuel at a consistent and known rate. Excess fuel bled off by the pressure regulator returns to the fuel tank through the fuel return line.
