What are the reasons for auto body shake

Auto Body slight jitter situation many owners often encountered. If the owners to start the vehicle or the vehicle is not suspended off the engine case, if you find a slight shake the car body, it may mean that the following three conditions exist vehicle:

If the driving process, found the body there is a slight jitter or offsets, it is generally caused by tire failure. First, the tire may be poor balance, you need to go as soon as to the car repair shop to do the wheel alignment and balancing, there is a simple way, using Auto Diagnostic Tool to do a correction.

Another condition is more serious, possibly because rim distortion, which requires owners to go to a professional repair shop to check. This situation generally occurs in the use of five-year vehicles. General motors to replace the new tires, new rims when to do a tire balance, otherwise the weight does not mean when the steering wheel is prone to jitter phenomenon. The body jitter can have an effect on driving comfort and control judgment. There is also a simpler way, using the Launch X431 GDS or Launch X-431 PAD tool to check whether the tire is balanced, if the balance, is not required to the repair shop.

The third case is because the transmission shaft deformation caused by the imbalance, it typically occurs in the chassis of the car had a collision.

If there is to start car the body shaking, the fault is for equipment manual transmission vehicles, such as: from static started and slowly lift the clutch pedal, the vehicle vibration. This is due to a clutch three piece suit (flywheel, clutch plate and pressure plate) the irregular wear, in which one or a few pieces to produce deflection caused by, in the bonding process, clutch disc can not be smoothly joined, but a joint, a little and release of the engine power is just beginning to transfer, and suddenly slipped, replace the clutch three sets of damage, in using Autel Maxidiag Elite MD701 or Autel AutoLink AL609 tool for the detection of gearbox is working properly.

How to check the working condition of automobile shock absorber

Automobile shock absorber is mounted on an automobile chassis parts, it is used to shock absorption, simply put, is in the car through the rugged road, shock absorbers allows occupants to reduce the bumpy feeling, also can effectively keep the car running smooth. Automobile shock absorber is also have the use fixed number of year, use after a period of time may fail, you can use Auto Diagnostic Tool to check the performance of automotive shock absorbers, following will teach you how to check the car shock absorber the working conditions.

To determine if there is no damage automotive shock absorbers have a good way, that is in the ground at low speed, and then brakes, if you feel the car shake very badly, that's the shock absorber problem, or when driving in uneven road , the body feels a strong sense of bumps, it is also possible that poor shock absorber effect. In this case should go to the 4S shop, using Launch X431 IV GX4 or Launch X431 GDS professional tools overhauled.

If you want to check the shock absorber, we can first and the lower end of the shock absorber fixed in a vise, with hand drawing compressed several times, the normal shock absorber should have certain damping force, and to the tensile resistance should be greater than the compression resistance. If the unstable or no resistance may shock absorber lack of oil or damaged parts, should overhaul or replacement parts.

If only one side of the shock absorber to fail, it is suggested that the two sides of the change together, it is no use in a separately. Change is the need to use Autel AutoLink AL439 or Autel AutoLink AL609 tool to check, one can check whether automobile shock absorber has a good working, by hand Press a few bumper car, if the car can play two or three times, the automobile shock absorber works very well.

Check the contents of the automobile brake system

Whatever the ultimate brake system is by the brake pad or brake shoe to complete brake function. Therefore, to check the thickness of the brake pads or brake shoes regularly. When they find it close to or less than the thickness of the minimum thickness specified by the manufacturer, should be replaced immediately. Check the brakes at the same time, also check the brakes or brake drum wear, if use Auto Diagnostic Tool to check the contact surface dents, the need for timely disc or drum, to ensure the brake pads contact area improve braking force.

In addition also need to check the brake fluid level, if that brake fluid level is too low, should be appropriate to add brake fluid (must add the same brand of brake fluid, different brands of brake fluid in the brake after mixing pipe may corrode and affect brake effect), the height of the liquid should be maintained in brake oiler scale division line between the upper and lower bounds, and then use the Launch X431 Diagun III or Launch Creader VI tools to check the brake fluid working is normal.

Mainly from the maintenance of brake fluid brake fluid selection and replacement of two aspects, in the selection of brake fluid, depending on how the performance, the best buy brand name products, quality and security. If the brake fluid fouling, emissions from all brake fluid and flush the entire system, then use the new brake fluid filling cylinder.

Do not re-use brake oil, all be discharged from the system of the brake fluid should be discarded, if you continue to use the brake fluid in the case of deterioration, will be on the brake master cylinders, wheel cylinders, hydraulic control unit and other components It produced affecting the normal operation or even damage the brake and performance degradation or even brake failure. Cause accidents, affect the safety of personnel and passengers, so check the car's performance on a regular basis, Autel AutoLink AL609 and Autel MaxiDiag Elite MD802 is a professional tool for checking vehicles.

The six functions of fuel additive

Function one, lubrication. Fuel additives replacing lead to lubricate the upper part of the engine block, the engine is smooth, not dry, improved power, lower fuel consumption. If you want to know more information, you can use the OBD Diagnostic Tool to check.

Function two, full combustion. When burned, small water microemulsion particle effect at high temperatures swept into the steam generation "micro-explosion" so that the combustion flame propagation is more uniform and delicate, so that the gas atomization is improved, so as to achieve complete combustion.

Function three, antioxidant. Fuel additive antioxidant ingredients can inhibit from fuel components in unstable components and a little olefin diene in the environment under the effect of temperature and air oxidation condensation formation of glial process, avoid the metal surface oxidation of automobile engine, to ensure the normal work of the engine. You can use the Launch X431 Creader VIII or Launch Creader VII tool to test the performance of the engine.

Function four, rust protection . Fuel in the storage and use process, there will be water, can cause rust, oil system for vehicle fuel additives can prevent the rust of pipelines and oil system.

Function five, anti-corrosion. Fuel to meet in the process of transportation, storage, use water caused by the oil emulsion, the oil-water boundary and form slag emulsion cream, cause the clogging in filter, and oil emulsification easy to moisture into the air intake system and combustion chamber corrosion and impact the normal operation of the engine, and composition of demulsification can prevent corrosion and affect the normal operation of the engine.

Function six, clean. Fuel additives contain pollutants, it has been adhered to in other parts of the heating surface grease, gum and carbon deposits in the combustion chamber of the role of pine, making it easy to be in the air in "clear", and after combustion exhaust. Carburetor vehicle hydraulic system, EFI car nozzle, intake valve has the function of keeping clean, using Autel MaxiTPMS TS401 or Autel AutoLink AL609 tool reads the carburetor real-time data.
