Idle jitter
If you want to find out the cause of car jitter, you must first judge what kind of jitter it is. Idle jitter can be divided into engine jitter and bracket damage jitter, which is difficult for ordinary car owners to judge by themselves. It is recommended to go to the repair shop for inspection. Engine jitter is mostly caused by the concentration of mixed gas, and there are various solutions, but in most cases it can be solved by replacing the fuel nozzle, fuel filter and cleaning the carbon deposit on the valve. But the garage must first judge whether the problem is gas shortage or oil shortage. When you come up, you have to wash the carbon deposit and change the nozzle, which costs a lot of money.
Low speed jitter
Low-speed jitter is mostly due to tire or rim problems. This reason is easy to solve. Generally, it is caused by tire or rim deformation and can be replaced directly. The deformation of rims can save money through post-shaping, but no matter how boasted, the reality is that the original rims data cannot be recovered after sale, and the strength will be affected to some extent, which is not recommended.
High-speed jitter
The reason of high-speed jitter is mostly due to the problem of dynamic balance. Among them, the reasons of dynamic balance failure are divided into wheel dynamic balance failure and axle damage. After inspection, if it is a wheel dynamic balance problem, it can be directly rebalanced to solve the problem. If it is a damaged half shaft, it can only be solved by replacing the half shaft. There are many organizations that repair axle shafts in the aftermarket of automobiles, but it is still not recommended to use the repaired axle shafts, which is prone to potential safety hazards.
Brake jitter
Brake jitter is the steering wheel jitter when braking, which is also very common and is caused by the problems of brake discs and brake pads. Normal wear of brake pads will not cause jitter, but will only slowly affect braking. Therefore, this situation must be that the surface of the brake disc is no longer flat and concave due to abnormal wear, so the brake pad is also abnormally worn. When braking, uneven joints will cause jitter to be transmitted to the steering wheel. When brake jitter occurs, all brake discs and brake pads need to be replaced, and single replacement cannot solve the problem.
Most of the jitter can be solved by the above methods. When the car owner encounters the jitter problem, he must find a reliable repair shop to check it in detail and find out where the problem lies. If he is shaken, he will sell fuel treasure's products.
