What should I do if the Mazda3 half shaft is abnormal, and how to solve the abnormal noise of the Ma

Night Ghost & Depending on what you're complaining about, it's a half-shaft slink. The sound ** is in contact with the half shaft of the hub, and the end face is instantly sticky and abrasive. Generally, there will be a "click" sound when accelerating at low speeds.

The solution was to install a special gasket, specially designed and manufactured by Mazda, and coated with a disulfide phase coating that reduces the wear coefficient and grinds on the surface. This is the best solution at the moment, and it works well.

In addition, after installing gaskets, if there is the same problem, even if the vehicle is out of the warranty period, the manufacturer will still be responsible for solving it.

According to the phenomenon you described, this abnormal sound should be caused by the wear of the wheel bearing, when the wheel bearing is worn, the abnormal sound will increase with the increase of vehicle speed, whether it is the gear driving, but also the neutral sliding, the abnormal sound will appear, it is recommended that you immediately go to the 4S shop to check the rear wheel bearing, so as not to break down on the road can not drive; Regarding the fault of idle instability, focus on checking the carbon deposition of the throttle body, if there is carbon deposition in the throttle, it will lead to the failure phenomenon of unstable idle speed and the engine is not easy to start, first check the carbon deposition. Hope mine is helpful to you.

If you doubt a bearing or a propeller shaft! You jack up the right front wheel!! Just top the right side (because the right side rings) Don't top with other wheels!

Be safe, don't use a small jack!! Start Gear in D gear, come on! Now only the right money wheel is rotating (using the differential principle), ask the master to listen to the right front wheel.

I know if it's a bearing and a drive shaft!!

If the car has had a major accident before, it may be that the girder is not right! Then go and straighten the girders!

You're done swapping it out, and there's no parts to replace. If it doesn't work, it is recommended that you find two good tires to put in front (preferably new), do the dynamic balance (focus), and do the next 4 wheel alignment! That's pretty much it!!

It's all typed word by word! If you don't understand, ask me again!

And there's an obvious copy upstairs that you still want to ask, I really don't understand!! aecjipzr |”

I hate CTRL+C the most....I hope everyone will boycott them together!!

Do you need to make sure the sound is the engine? Transmission? Shock absorption? Or if there is a gap in the frame or an exhaust pipe leaking! You'll have to decide where you want to go!

The sound of tires is too much gas. If high speed is obviously a tire balance problem, it is good to do a tire dynamic balance.

When the suspension system is abnormal, it is recommended that you follow the following steps to judge:

1. Check the tire pressure; High pressure will cause abnormal noise, which can be solved by adjusting it to the specified value;

2. Check whether there is abnormal damage or loose nuts at the connection of the upper and lower ends of the suspension body; Any loose connection will cause abnormal noise, which can be solved after tightening;

3. Whether the self-locking nut on the upper part of the piston connecting rod of the shock absorber is tightened, and whether the bolts and nuts connected at the lower end are tightened. Any loose connection will also cause abnormal noise; It can be solved after fastening;

4. Whether there is damage to each part of the strul, check whether the vibration isolation block, buffer block, spring upper and lower cushions, pressure bearings, etc. are damaged, or whether other parts are damaged, and the damage is found to be replaced;

5. Conduct pressure test on the shock absorber, press the body or compress the shock absorber by hand after disassembling it to listen to whether there is any abnormal sound, and replace it if there is a problem;

That's what you said about these two shafts, because the surface is flat, which causes noise.

According to your brief description of the above situation, this situation is mostly caused by the failure of the airbag spiral cable, which is caused by poor lubrication. If the fault of the side transport fruit is more obvious or the frequency is relatively high, then Yun Huliang suggests that the maintenance franchise store technician conduct on-site test judgment and give reasonable maintenance suggestions.

1.Carbon deposits can cause insufficient combustion of gasoline and cause the engine to shake. The impact of engine carbon deposition on the car is quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless.

The second is to increase fuel consumption and increase your financial burden. The third is the difficulty of cold start, that is, the difficulty of ignition, it is not easy to get on the car, and finally the carbon deposit in the combustion chamber is strict, and a heavy one will also cause cylinder detonation, and there will be a sound of low-speed acceleration, which will cause damage to the piston and crankshaft, and cause high temperature of the engine, which will seriously affect the safety of the car. Then there is the excessive discharge, which not only fails the annual inspection and inspection, but also directly aggravates the harm of polluting the environment.

2.Transmission load operation will destroy the quality and friction characteristics of the transmission oil, increase friction and wear, transmission noise will follow, and at the same time, sludge (impurities or dirt) will also be generated inside the transmission (such as the valve body), resulting in transmission frustration, out-of-gear, impact, slippage, abnormal noise, delay, high temperature, oil leakage. (Audi and other high-end models will call the police and enter the transmission protection mode) If it is not solved in time, the transmission will be scrapped.

Therefore, only by removing the stubborn dirt and impurities in the gearbox and effectively controlling the working temperature of the gearbox can the gearbox problem be completely solved and prevent its recurrence.

3.Decreased lubrication leads to mechanical wear.

In this case, the brake pads and brake discs are rubbing. After a certain load is generated by the cover in the corner, the bearing will be tilted to a certain extent, and the brake disc will be driven when it is tilted. Usually, the gap between the brake disc and the brake pad is very small, and the load is generated after tilting, and the friction between the brake pad and the brake disc makes an abnormal sound.

You need to go to 4s for brake pad processing.

This friction will not last for a long time, does not affect the normal braking and dismantling of the ruler of the vehicle, and will not affect the driving safety. You can step on the brakes several times to work on ABS, and it can generally be eliminated by stepping on the brakes a few times.
