1. Clicking Noise While Turning
Probable Cause: Failed outer CV joint If your car is making a click make noise when turn, it is likely you have an out CV joint ( constant speed joint ) that has failed because of a pluck boot or old historic period, most probably a tear boot. Without going into excessively much contingent about what a CV joint is, I will equitable give you a basic estimate of its function and why it might have failed .
What Are CV Joints?
A CV roast is a laid of ball bearings at the inside and out ends of an axle. It lets a spinning axle bending while it ’ second distillery spinning ( see this cool animation if you like ). A rubber “ boot ” covers the stallion joint and protects it from scandal, debris, and moisture, while holding in the grease that lubricates the ball bearings . A CV joint lets an axle bend while it is spinning Nutzdatenbegleiter via Wikimedia Commons ( CC BY-SA 3.0 ) Over time, since it ’ s merely rubber, the kick becomes brittle and dry. finally it will split open and allow specks of soil and debris to enter the joint. once alien topic mixes with the dirt, the wrong begins, and it is only a matter of time before the CV joint starts to make a click randomness when turning. This clicking noise while turning will start out faint, but gradually it will become obtrusive and finally very loud .
How to Fix It
The only way to fix this condition is to replace either the wholly axle assembly or the extinct CV joint. My professional public opinion is that it ’ s better to replace the entire axle assembly ; it ’ mho normally cheaper, even if you can evening find the out joint sold by itself, and it does n’t make a lot sense to mix old parts with newly parts .

2. Water Pump Noises
Probable Cause: Failed water system pump Water pump noises are identical unmanageable to diagnose, because the body of water pump is by and large buried deep in the motor, and the noise will resonate through the engine making it unmanageable to identify. The body of water pump on your locomotive is a chummy metal casting containing a pulley, pump fins ( a palm-sized propeller to push the water along ), and a bearing set. When a water pump fails, the randomness is normally caused by damage to the bearings. The video below is a great example of what a noisy water pump sounds like .
How to Verify the Sound Is Coming From Water Pump
If you suspect your water system pump is the perpetrator for the noise in your car, try to locate the water pump on the engine. if you can see the cast of the water pump, you can pinpoint the noise by holding the end of a long screwdriver against the draw and putting the other end of the screwdriver against your ear ; if the bearing is bad you will hear the make noise through the screwdriver. ( See the video below, under “ Using a screwdriver like a stethoscope. ” )
The entirely repair for a noisy water pump is to replace it. Because of its localization ( frequently under the time knock shroud and bolted to the engine block ), an nasty set of parts have to be removed to get to it, so it can take several hundred dollars deserving of labor to replace a $ 50 depart. If it is closely prison term for a everyday timing knock substitution ( every 60,000 to 105,000 miles or therefore depending on the cable car ), you might want to have that done at the lapp time as the water pump, because timing belt service is one of the rare occasions when a water pump is easy to get to. In fact dealerships will often want to replace your water system pump routinely, whether it ’ s worn out or not, as contribution of a time belt service .

Using a Screwdriver Like a Stethoscope
In the video recording below, the mechanic uses a screwdriver like a stethoscope, pressing it against the hub of a bicycle to listen to a wheel bearing noise .
3. Squeak or Squeal From an Engine Belt
Probable Cause: Dry, cracked, or loose engine knock ( precisely needs to be replaced ) engine belts can create a loudly, high whine or squeal that will drive you and your neighbors crazy. Some locomotive belts only squeak after you go through a big pool or if there is heavy moisture in the air, and others squeak constantly. If your engine belts squeak lone when muffle, you credibly only need to have the belts adjusted. If your belts squeak constantly, they may be dry, cracked, or free, and credibly need to be replaced .
Does Belt Dressing Work?
Some folks like to use a spray called “ belt dressing ” to stop the locomotive knock squeal or squeak. Keep in judgment that this spray will not fix anything permanently. It is, however, a great creature for diagnosing the randomness and finding out which belt the randomness is coming from. If you have belt dress, this is what you do : when the engine is running, just spray it on each belt to see which belt starts to quiet down. Inspect your engine belts for cracks, damage, and tension, and replace or adjust them as needed . This serpentine belt is dried and cracked on the buttocks of the belt and was making a loud screaky randomness. Eddie Carrara This serpentine knock is dried and cracked on the buttocks of the belt and was making a loud confess make noise, the rib side was cracked just as bad. Eddie Carrara

4. Exhaust Heat Shield Noises
Probable Cause: Damaged hotness shield A estrus carapace noise is a type of rattle you hear while your car is idling, or at a specific engine accelerate or RPM. Heat shields are alloy plates along the exhaust system of your car that debar heat off from the shock of your fomite and other heat-sensitive components like fuel tanks, wiring, and brake lines. As the exhaust arrangement ages, sometime the heat shields start to rust at the hold-down points and become informal. If this is your problem, the engine vibrations will cause an awed noise as you ’ re sitting at a check abstemious or as your cable car is idling in the driveway warming up. It sounds like rocks being shaken on a cookie sail .
How to Fix It
Heat shields can become discredited due to road debris, snow banks, automotive lift, and just plain old historic period. In some cases, a damaged heat carapace can be removed temporarily without causing any repercussions, but it ‘s best to replace them a soon as possible. An automotive exhaust system can become highly hot, even 1000o Fahrenheit if you are running your locomotive at high RPM for long periods, like on the highway .

A Car-Buying Secret
car noises are inevitable ; evening new cars have noises that need to be fixed. here ‘s a little tip off that not excessively many people know about. When buying a new car, if potential, find out what day it came off the forum telephone line. Watch out for cars built the day before a holiday, or on a Friday afternoon. It may sound amusing, but humans are building these vehicles, and you know what happens at 5 o’clock on Friday or at close up time the day before a vacation : we rush our work so we can head home to relax or prepare for the vacation. This is not a fact I found in a documentary or anything, it ‘s good my experience. When our shop class saw newfangled cars with a lot of little problems, it seemed like they were always built on these out-the-door days .
