A whining noise is caused by a faulty power steering pump. When the pump has air in the system or has trouble creating pressure, it produces a loud whining noise.Know More
As a pump is continually used, the seals inside the unit become worn. When these seals fail, they form leaks that drain out the power steering fluid. When the fluid is almost complete drained from the system, the steering wheel will have dry spots when turning, and the pump will begin to whine. Without repairing the leaks, the pump will eventually fail.
There are commercial products available that contain additives to help slow power steering leaks, but the best option is to replace the unit and hoses themselves to ensure a leak-free pressurized system.Learn more about Engine
Engine backfire is caused by an imbalance in the air-to-fuel ratio of the vehicle. Backfires occur in one of two places. A backfire in the intake manifold is caused by a ratio that is too lean (not enough fuel). A backfire out of the exhaust system is caused by a ratio that is too rich (too much fuel).Full Answer >

Engine knock can be caused by an incorrect air/fuel mixture within one or more cylinders. The knocking sound is the fuel burning unevenly and creating shock waves at the wrong times. The waves can damage the cylinder wall as well as the piston.Full Answer >
Engine noise under the hood may be caused by loose torque converter bolts, low oil pressure, spark knock or excessive piston clearance. A cracked flywheel on an automatic transmission or excessive connecting rod clearance may also cause an engine to knock.Full Answer >
