This issue is caused by excessive clearance between the driving and driven bevel gears inside the main reducer. To resolve the problem, remove the main reducer located in the middle of the rear axle housing and adjust the clearance between the driving and driven bevel gears to 0.2-0.4 mm. Below is a detailed introduction to the driveshaft: 1. Introduction: The driveshaft is a high-speed rotating body with minimal support, making its dynamic balance crucial. For front-engine, rear-wheel-drive vehicles, it transmits the rotation from the transmission to the main reducer. It may consist of multiple sections connected by universal joints. 2. Composition: The driveshaft is composed of an axle tube, a telescopic sleeve, and universal joints. The telescopic sleeve automatically adjusts for changes in distance between the transmission and the drive axle. The universal joints ensure changes in the angle between the transmission output shaft and the drive axle input shaft while maintaining constant angular velocity transmission between the two shafts.

What is the maximum wading depth of the BMW X5?

According to official information, the maximum wading depth of the BMW X5 is 500mm. Common tire specifications include 275/45R20, 275/40R21, 305/40R20, and 315/35R21. The vehicle has a body length of 4930mm and is a 5-door, 5-seat SUV. The maximum wading depth refers to the deepest water level a vehicle can safely pass through. Generally, the maximum wading depth for sedans does not exceed 30cm, while SUVs have a higher wading depth, though it is still advisable not to exceed 50cm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30cm, the Audi A4 has 32cm, the Volkswagen Sagitar has 30cm, the Land Rover Range Rover has 90cm, the Jeep Compass has 48cm, and the Highlander has 45cm. The maximum wading depth of SUVs is significantly higher than that of sedans. Generally, when driving through water, vehicle owners should take different measures depending on the water depth and the vehicle's characteristics, as outlined below: If the wading depth reaches the height of the exhaust pipe, it is relatively safe. Even if water enters the exhaust pipe, the pressure inside is sufficient to expel the water. As long as the engine is not turned off in the water, water will not flow back into the vehicle. If the wading depth reaches the height of the door frame, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly located at the bottom of the car, which could lead to circuit failures, damaging critical electrical components and preventing the car from starting normally. If the wading depth reaches the height of the air intake pipe, it is extremely dangerous. Driving directly into such conditions may cause the vehicle to stall immediately, resulting in permanent engine damage or rendering the engine unusable.

What Causes the Car Body to Shake During Ignition?

There are several reasons why a car may shake suddenly during ignition: 1. Poor fuel quality: In winter, the lower temperatures make it difficult for the fuel to atomize when starting a cold engine, leading to insufficient mixing of fuel and air in the cylinders, which causes difficulty in starting and severe shaking of the car body. 2. Spark plugs: The gap between the electrodes of the spark plugs gradually widens, reducing ignition energy and impairing fuel atomization. 3. Ignition coils: Aging ignition coils, high-voltage wires of the spark plugs, or electrical leakage can decrease ignition energy. 4. Carbon buildup on engine valves and intake manifold: Carbon deposits can absorb a certain amount of fuel, causing the electronic control unit to miscalculate. For example, while the unit may command the injection of 100 units of fuel-air mixture, only 90 units actually reach the cylinder. Even if the remaining 90 units burn completely, the required power output is not achieved, leading to unavoidable shaking.

How Many Keys Come with a New Car?

Generally, a new car comes with two keys. These two keys are the master key and the spare key. For some car models, the master key and spare key may have different designs, while others may have identical ones. Here is some relevant information about the two keys: 1. Functions of the two keys: Typically, the spare key only has basic functions (such as trunk unlocking, locking, unlocking, and vehicle locating). If the master key is a standard key, the spare key is usually the same. 2. Purpose of the two keys: Both the master key and spare key can be used to lock and unlock the vehicle. If one key is lost, the other can still be used to start the car. Additionally, both keys usually come with a mechanical key, which is a traditional metal key. When the remote key battery dies, simply remove the mechanical key from the master or spare key and insert it into the car door's mechanical lock to unlock the vehicle.

How many kilometers does the Audi Q3 fuel filter need to be replaced?

Audi Q3 fuel filter generally needs to be replaced every 10,000-20,000 kilometers. Of course, the actual situation should be taken into consideration when making the decision. Filter turns black: If the filter is noticeably blackened, it needs to be replaced even if it hasn't reached the specified replacement interval. However, it should be noted that when replacing the fuel filter, the engine oil, oil filter, and air filter should also be replaced. Classification of fuel filters: The fuel filter is abbreviated as fuel filter. There are carburetor type and electronic injection type fuel filters. For carburetor gasoline engines, the fuel filter is located on the inlet side of the fuel pump with lower working pressure, usually with a nylon shell. For electronic injection engines, the fuel filter is located on the outlet side of the fuel pump with higher working pressure, usually with a metal shell.

Is Replacing the Radiator Considered an Accident Vehicle?

Simply replacing the radiator does not classify a vehicle as an accident vehicle. Here is more information: 1. Vehicles that are considered accident vehicles. Under normal circumstances, the radiator is not easily damaged. If a vehicle's radiator is replaced, it usually indicates an accident. If the radiator frame is integrated with the vehicle's body frame, replacing the radiator frame would classify the vehicle as an accident vehicle. 2. The function of the car radiator. The car radiator, also known as the heat exchanger, is responsible for cooling the circulating water. To prevent the engine from overheating, components around the combustion chamber (such as the cylinder liner, cylinder head, and valves) must be properly cooled. The car engine's cooling system primarily uses water cooling, where circulating water in the cylinder water passages cools the engine. The heated water from the passages is directed to the radiator, cooled by air, and then returned to the water passages. Additionally, the radiator serves as both a water reservoir and a heat dissipation device.
