Four-wheel location is very important
Coarse, car on the four wheels seems squarely on the ground and upright, actually otherwise, if use instrument to measure, they will find them in the X, Y, Z three plane deflected than an Angle, but only commonly, numerical small 2 degrees, 0.5 to naked eye can't see out. Don't underestimate the three little deflection Angle, which determines the car to performance. If there was a crash, or use for a long time due to wear and changed, playability will greatly reduced. So if you are manipulating the steering wheel, should be to a formal or professional four-wheel location checkpoints go check, and the corresponding adjustment. Inexpensive, ensure the safe driving.
Cars often meet rain, snow weather, chassis contact water is easy to rust. If using the method HuaDong snow salt, salt water can accelerate the corrosion of steel, In poor road, splash wheel will also blend, blow chassis gravel. Therefore, some manufacturers recommend the chassis spraying a protective coating, in order to improve the ability to reduce impact and anti-rust, prolong life. The chassis,
However, this will also a concrete analysis, now many medium and high-grade car has used double-sided galvanized steel, in the space may be shipped water are adopted, generally using wax technology injection 10 to 15 years. Some car at the bottom plate with rust, all avoid water, and reduce aerodynamic drag. For this kind of car is not necessary to gild the lily.
Chassis is key. Maintain tires
High speed will tire burst if big accidents, small and great, ShuaiTou, heeling overturned. Even if lucky accident in the street parking, no change tyres definitely not a pleasant thing, so, each vehicle tyre condition before check is necessary.
First check tire pressure
Air pressure is too high, tire easily burst, especially in the summer, And low pressure increases, oil resistance, car increased accordingly. So, before the car manual marked the provisions are not tire pressure. In order to facilitate the users, each car driver post nameplate is clearly above. Of course, sometimes to adjust according to the circumstances. For instance, on the road is all wet slippery, hot weather, pressure is lower. Small (title) often check tire surface often in bad conditions, is frequently check tire tread on any sharp nails, stone and glass, lest stabbed tires. Tire surface wear pattern to a certain extent, it needs to be replaced. Usually when pattern to wear only 1.5 to 2 millimeter, will find on the tyres have a specific markers appear, different grades of tyre mark is different, but in all directions. This will change a tire.
After driving certain mileage and exchange
