Car making grinding noise
It is important to determine the cause of the grinding noise. Follow these simple steps to try and determine the source.
Step 1: Start Your Vehicle
Once you start your vehicle, listen to see if the grinding sound starts right away or if it begins any time while the engine is running. If you don't hear the grinding, then go to Step 5. If you hear the grinding the go to Step 2.
Step 2: Lift The Hood And Locate The Alternator, Water Pump, and Power Steering Pump
You need to figure out where in the engine the grinding noise is coming from. If you are not familiar with the different parts of your engine, then look at your owner's manual or look online for a diagram of the parts of your engine to help you recognize the alternator, water pump, and power steering pump.
The following video will let you hear what a grinding noise from an alternator will sound like.
Step 3: Listen To The Alternator With A Piece Of Hose
Once you know what each of these parts looks like, listen to each one to see if the noise is coming from it. According to ItStillRuns.com, a great trick for listening to each separate part is to take a piece of a rubber hose and place one end on the alternator and hold the other end up to your ear. The hose will help you to determine if the problem is with the alternator. If you hear the sound coming from the alternator then it will likely need to be repaired or replaced.
Step 4: Listen To The Water Pump And Power Steering Pump
If the grinding noise was not coming from the alternator then repeat Step 3 but this time listen to the water pump and the power steering pump. If the grinding noise comes from either of these parts, then they may need to be repaired or replaced. The picture below shows a power steering fluid reservoir and pulley driven pump on a Jeep 2.5.

Step 5: Drive The Vehicle And Test The Brakes
While you are driving, gently touch the brakes. If you hear the grinding sound, try braking a little harder. If the sound gets worse, then you may have worn brake pads. Stop the vehicle and take a look at your brake pads. If you are not sure where to look, consult your owner's manual. If the pads are a quarter of an inch thick or less, then they probably need replaced.

Step 6: Drive The Vehicle And Make A Right And Left Turn
Start driving your vehicle and make a right-hand turn and then make a left-hand turn. If the grinding noise gets worse when you turn in one direction and then gets better when you turn the opposite direction, then the problem is most likely a wheel bearing. Wheel bearings are vitally important to your safety and should not be ignored. Make sure you take your vehicle to a reliable mechanic as soon as possible to get it repaired.

Step 7: Drive The Vehicle And Listen Carefully As You Change Gears
If you hear a grinding noise while your car is changing gears, then the clutch could be getting worn or it may need to be adjusted. It also could mean that there is a problem with your transmission. Don't take chances with either of these issues. If you suspect that it is your clutch or transmission, then you need to have these checked out by a professional.
