Find basic operational malfunction of the car

There are people who are driving, do not hear anything at all, and yet the sound of a car can help the owner find the basic operational malfunction of the car. The existence of the problem, the driver is always alert sound, except for an overheating engine and oil pressure drop. When you get used to the car, then surely hear it objectively becomes difficult, and heard the sound of the defect immediately, it increases gradually. Let's experiment. Start the engine, then open the hood and vynem dipstick, then you have to wipe it clean with a cloth, insert it into a rounded end at the sink of his ear. The entire structure needed to squeeze his hand to his head and gently pristavlyat end of the probe to different parts of the engine. Do not forget that we need to fear its moving parts. You will hear many sounds, and they will all be very different. This method usually helps out in the field, where a number of service stations is not expected, but do not have my right tools. Using it is easy to distinguish the sound of the rushing of the pump, say fuel pump drive, and the sound of bursting of the piston pin knock on the connecting rod bearing, etc. The most convenient way to listen to the chassis of his car in places where it is easy to be reflected sound (wall, tunnel, fence). You must first learn to distinguish between the engine speed to wheel speed, as well - from the same body movements. On domestic cars is not that hard to do all the units basically create a lot of noise, even when new. The most famous of sounds - "bu-bu-bu," a noise of wheels with the impact of the wheel. He says that the wheels have a "bump" - inflated sides wheels. Beating the steering wheel and body vibration, says that your wheels - "eight" tires. You can self-diagnose wheel: pick up your car on the jack, and turn the wheel or by hand or by motor, if the wheel of the lead. Need to inspect the wheel in front and behind - along the axis of the car on his drive and the tire. Beating the wheel should not be seen to the eye. "Szyszko" - can be seen at once, you can certainly try to put a rubber patch, but better than what the wheel is replaced by a new one. Non-uniform mass distribution of wheels, there is an imbalance, this defect is very unpleasant in the operation and the comfort of your car can be forgotten. Wheels need to be adjusted urgently. If you knock the shock absorber, the sound is dull, you need to quickly change the rubber bushings, until repairs could cost you not much. When the sound of metal, there is a risk that a lot of time spent on welding brackets provarku bottoms, etc. Absorber usually knocks on the place of its attachment to the suspension or the body itself. Knocking ball joints can be heard moving streetcar tracks. Engine malfunction, which are expressed in a knock when operating a car - not so much. The most common is the sound of the valve, a few or one, it will be dry and click. The second popular knock - whistling, ringing or roaring chain camshaft drive. The addition and dropping of gas during the operation - the sound is changing, it is its distinctive feature. If the car is not old, the chain can pull the most, if not help, consult a specialist. Most unpleasant knocking engine - it's the sound of rod and main bearing crankshaft. Need a major and expensive engine repair, the cost of which is about 2 / 3 the cost of its price. First, they knock barely audible and it gives us hope that everything will cost. When main bearing knock, oil pressure drops, while knocking rod, not necessarily. Time to change the cardan shafts, if you hear the ringing clicks from the bottom of your Zhiguli. The normal suspension should work quietly, and all defective sounds suspensions are related to road irregularities. To test the shock absorber, greatly needed to swing the corresponding wing and if the car will swing more than once, your bad shock, vibration, must be extinguished immediately. Frequent failure Zhiguli brake cylinders are marked under braking, they can certainly be replaced, or you can simply disassemble and clean up with a "velvet" skin mirrors cylinders. If the knocking only during the turn, then the faulty bearing hub, the fastest front-wheel or faulty constant velocity joints. If tinkles in the area of ??the rear wheels, then blabbed spacer bracket parking brake. The bar to turn 180 degrees, and the wheels and drums must be removed. Very often on roads potholes start ringing, knocking, lining or shields the wheels, try to do without them. And yet the most unpleasant and common sounds are rattling car parts in the cabin or on the dashboard. You can write about this whole affair, we certainly will not do that, the main thing is that even an inexperienced man, to distinguish them from serious knocks in the car. Much Ado create "Muscovites", "Nine", "Eight" and "ninety-ninth." Of course, it is possible that - then spread mastic, close up chewing gum, glue tape - but this is not an option, but only a temporary measure. You can still buy a heavy mastic adhesive, remove to a warm summer, instrument panel trim with doors, seats and try to glue it all very carefully. Check to see whether the knock in the car door. To do this outside, in the vicinity of the castle, strongly press the door into the depths of interior and if the play is, grab a screwdriver to open the door, and then to loosen the screws receiver shackle lock, and gently tapping with a hammer to remove it again into the depths of the cabin, approximately somewhere in the amount of movement the door. Then tighten the screws well and check the door - knocking more should not be. The effect is simply stunning! Your car will run silently, and will, like the Mercedes, which certainly will make you happy and give tangible comfort when operating it on the road.
