Some have a car as a friend , you want to do to your car is quite familiar , is not only convenient and safe for you to travel , it is also learned to make better maintenance car , the wheel bearings when you use things you have to understand , oh. According Hengding automobile hub unit is understood that the specific considerations can be divided into the following six :
1, the first thing you do is to check regularly approach suggested wheel bearings, whether loose , wear and other issues,
But if there strange , then , that you should be careful not faulty wheel bearing , wheel hub is a problem . Such situations occur , you must be vigilant to see you go , lest a security risk.
Under normal circumstances, two , can not hear the sound , should hear the wheel bearing parts issue a strange noise , then you should watch , and be sure to find the location of the noise occurs . There might be some rotating parts and no rotating parts in contact occurred , there may be the bearing is damaged , then you should also be replaced.
3 , wheel bearings require greater pressure pressing, so the need for any special tools in the situation , in addition is also important . In storage and during installation , the bearing parts can not be damaged.
4, before mounting the shaft and the bearing housing should also check the status of even slight wear will lead to poor fit , thereby causing early failure of the bearing .
5 Replace the bearings when the environment is very important , because , bearing more sensitive, does not allow the bearing with a hammer percussion , but do not let the bearing off the ground .
6 , the hub bearing unit , do not attempt to disassemble or adjust the wheel hub bearing seal unit , otherwise it would lead to water damage to seals or dust. Even ring and the inner ring raceway are damaged , resulting in permanent failure of the bearing.
Wheel bearings are functioning related to your ability to drive safely , so be sure not to overlook important parts of this small , but also develop good habits when using , do not arbitrarily low speed braking operation , in addition to routine maintenance is also very important , oh .
We usually say car maintenance , mainly to keep the car from good technical condition , prolong the life of the car were aspects of the work . In fact, the broader its contents , including automotive beauty care knowledge Hengding automobile wheel hub unit learned mainly in the following three aspects:
First, the vehicle maintenance
Also used to refer to the car body maintenance beauty . The main objective is to clear the car in vitro and in vivo in a variety of vehicles oxidation and corrosion , and then be protected as much as possible to highlight the car 's "beauty ." It includes : paint maintenance, carpet cushion maintenance, bumpers, skirts and maintenance, instrument panel maintenance, plating processing and maintenance, leather plastic maintenance, tires, wheels warranty, windshield maintenance, chassis maintenance, engine maintenance appearance .
Second, car maintenance
To make the car body maintenance is forever young , car maintenance , the aim is to make cars with hundreds of thousands of km without major repairs , ensure the car in the best technical condition. It includes : lubrication system , fuel system, cooling system , brake system , carburetor maintenance.
Third, body renovation
Such as deep scratches diagnosis, management, multi-material bumper repair , wheel repair flawed , leather, chemical fiber materials renovation, refurbishment and other engine color . Regular maintenance and vehicle maintenance is divided into two major categories of non- regular maintenance , periodic maintenance are: routine maintenance, a maintenance, two maintenance ; non- regular maintenance are: run-in period maintenance and seasonal maintenance. The main work is nothing more than clean vehicle maintenance , inspection, tight , adjustment and lubrication content. But with the development of science and technology and the automotive industry , with a variety of advanced computer-based technology is widely used in the car , so the next car gradually intelligence, and thus the content of vehicle maintenance has been given a new meaning.
Vehicle maintenance is a relatively high technical complexity of the work , I find it difficult to complete the driver alone , companies need to carry out repairs to the steam . And now in our country there are some car repair and maintenance companies stick to the traditional concept of letting go , maintenance equipment and tools obsolete , maintenance , or the same old methods and means need not meet with the modern development . In addition, the quality of service to individual repair business worrying for profiteering " black box " to the old charge maintenance to inferior charged , maintenance, replacement parts exorbitant fees . So remind drivers when vehicle maintenance must select strong technical force , reliable quality service and good reputation repair business , and not be bothered , plan to save money instead of vehicle maintenance , so runs the risk .
How to maintain the car
In the hot summer months, due to the high temperatures , rainfall and more dusty and radiant heat and strong reasons, especially in the automobile engine technology conditions change . In order to meet the needs of the normal operation of the car , before the arrival of summer , should be combined with secondary care for the whole car to make some necessary checks and seasonal adjustment :
Strengthen the use and maintenance of cooling :
A, careful to check for leaks in the cooling system , the tightness of the fan belt , thermostat and cooling water temperature sensitivity of the situation , etc., and note that there are plenty of cool water.
B, remove the radiator cooling system including water jacket adherent scale. Because the poor thermal conductivity of the scale , it will seriously affect the heat . 2 , switching to high-viscosity grade engine oil drain intervals and appropriate to shorten ; transmission and differential should be replaced by the summer of thick gear oil ; wheel bearings switching to a higher dropping point grease , according to the provisions for inspection cycle and maintenance ; air resistance in the brake fluid may occur at high temperatures, a high boiling point should be used brake fluid.
Many owners will prepare a duster customary in the car , but most of the owners have ignored this point: fluff will duster adsorbed on sand and dust , wipe the body paint if such a duster , is tantamount to using sandpaper friction paint , paint protection is obviously very unfavorable . How do sandstorm car beauty of it ?
( 1 ) Clean the air conditioning filter after the dusty weather , we should first clean up the air conditioning installed in the vehicle inlet filter , because as the weather gets warmer, the increasingly frequent use of air conditioning , if not promptly cleaned the air conditioning turned when the dust will follow the duct into the car, the car air pollution .
( 2 ) air filter to clean the air filter is designed to filter the air sucked into the engine to prevent the increase of foreign body aspiration engine wear and extend engine life. When dust weather , dust in the air will be many times more than usual , will be attached to the car's air filter large amounts of dust particles affect the engine air intake . So when after a sandstorm , it is recommended drivers and friends filtered out of the air , to clear up above the dust and the air filter assembly in a clean dust , which can greatly extend the life of the air filter , and to reduce fuel consumption also have a role .
( 3 ) Clean the car subtle Anyway beware , sand -day car or a little more dust than usual. When attention is most in need of cleaning up the dust may bring scratches, with particular attention to cleaning up some of the nuances , when the owners to clean the interior , use a soft cloth and a special cleaning agents .
( 4 ) Clean the wiper blades . This little place is easily overlooked by everyone . First of experts to correct a mistaken view of many people : the rain can wash the body clean.

So after the rain should be cleaned and wipe the vehicle , so you can better protect the paint . Besides, now that poor urban air quality, the higher the acidity of rain , acid rain is very susceptible to corrosion paint .
Rain must first conduct a thorough cleaning of the car to prevent rainwater for paint damage . For minor paint damage, such as acid rain , alkaline water points, aviation fuel and diesel oil, cement and other vehicles can be used to handle the mixture or polish . They pour a little on a soft cloth and gently wipe the stain along the scratches can be eliminated . If you can resort to some wax , the more glamorous .

If the improper exclusion of the owner or long-term maintenance of the tire pressure is too low , often rub shoulders outside factors such as the use is likely to be strongly alkaline washing liquid tire caused premature aging .
Choose good quality professional car wash liquid . Professional washing liquid PH value is neutral , that is, ph value of about 7. The car will not erode the surface , such as wax composition containing water , more body in the car wash while giving the effect of one kind of moisturizing care , even frequent washing , it will not damage the paint, but the more the brighter wash . Cleaning should be noted that the car clean is not only a cleanser and protection products . Due to various parts of the car different materials , and more messy , decentralized , should choose to use a different cleaning agents . The final step is to pay attention to the owners friends insisted : attachments cleared up paint surface.
At very high surface temperature, the asphalt on the road if the car gets , should immediately be removed , not free to use the blade scraping or eliminate the use of gasoline , so as not to damage the paint . Summer evening, especially after rain or driving at night , the film will be accompanied by many small insects, most of these small insects secrete acidic substances , if not promptly removed their secretions and body, there will be many small spots on the film , it is difficult restitution.
People often boast author of the car is well maintained vehicle age of 6 years the car looks like a two- car -like, in fact, I knew that this feeling mainly from my car intact paint , clean and flat paint always give people the feeling of a new car . Also, we often see some new car , but because the paint color, bump or even rust , giving the impression of old , in fact, a lot of cars may still be a year or two of a new car. Learn automobile paint seven major maintenance precautions to effectively prevent oxidation of car paint rust .

Therefore, both inside and outside edge of the wheel , doors, trunk bottom corner of the door frame of the keyhole and wipers moving parts , etc., should always be checked , while maintaining the smooth flow of the door and the body ministries drainage holes , check the car cover humidity , such as carpet , floor member to prevent rust .
Tip 3 : Soft enamel paint to make closure
Some paint softer vehicles traveling at high speed the process of sand particles hit the car body may also result in a fine relying marks. For such vehicles , the body can do to seal the glaze , which can form a mesh of solid protective film to improve the hardness of the paint , the effect can be maintained for about a year . The coating can achieve a similar effect. In addition, the bottom of the vehicle can be armored or sealed plastic chassis , which can protect the chassis acid rain , corrosion protective layer so that the original is not easy to dry and fall off , you can also prevent them traveling pebbles on the chassis of impact.
Tip 4: Do not cover the best sewing
Vehicles parked outside , the case of heavy rain, the weather , the inner layer of the garment will repeatedly beat the paint, especially if the garment blown into the sand , it will draw on numerous road car body tiny strokes marks , over time can also cause hair black paint . Also, do not use sand after duster or cloth to clean the sand directly to the car body , but should rinse with water, sand also in order to prevent scratches on the duster and wipes paint .
