How to Adjust Excessive Steering Wheel Play?

Excessive steering wheel play is usually caused by improper driving habits. Common issues include wear on the steering column universal joint, steering gear rack and pinion wear, and tie rod end wear. There is almost no way to adjust excessive play, and the following measures should be taken: 1. Check if the steering column universal joint is worn. If worn, it needs replacement. The steering column universal joint is essentially a universal joint that changes the direction of the steering column torque and prevents the steering column from impaling the driver in severe accidents. Wear on the universal joint can cause excessive steering wheel play and sometimes produce a clicking sound. 2. Inspect the steering gear rack and pinion for wear. If wear is found, timely replacement is necessary. When the rack wear is not particularly severe, the tightening force of the rack and pinion can be increased using the adjustment screw on the steering gear, but this will make the steering wheel heavier. 3. Check the tie rod ends for wear. If wear is present, replacement is also required. The steering gear has inner and outer tie rod ends. The inner tie rod end connects the tie rod to the steering gear rack, while the outer tie rod end connects the steering knuckle to the tie rod. Lifting the car and manually shaking the wheel can help feel the play in the tie rod ends and hear a rattling sound.

How much can you exceed the 80 speed limit on the highway?

On the highway, the speed limit is 80, and exceeding 80 is considered speeding. However, currently, generally speaking, exceeding the speed limit by less than 10% on highways or national roads results in a warning, without points deducted or fines imposed. Here are the consequences of speeding: 1. Exceeding the speed limit by less than 10% results in a 50 yuan fine and 3 points deducted; exceeding the speed limit by more than 10% but less than 50% results in a 200 yuan fine and 3 points deducted; exceeding the speed limit by more than 50% but less than 70% results in a 500 yuan fine and 6 points deducted; exceeding the speed limit by more than 70% but less than 100% results in a 1000 yuan fine and 6 points deducted, and may also result in the revocation of the driver's license. 2. Exceeding the speed limit by 100% results in a 2000 yuan fine and 6 points deducted, and may also result in the revocation of the driver's license; exceeding the speed limit by less than 20% results in a warning; exceeding the speed limit by more than 20% but less than 50% results in a 100 yuan fine. 3. Exceeding the speed limit by more than 50% but less than 70% results in a 500 yuan fine (1000 yuan on highways), and may also result in the revocation of the driver's license; exceeding the speed limit by more than 70% but less than 100% results in a 1000 yuan fine (2000 yuan on highways), and the revocation of the driver's license.

How Many Minutes Should a Car Air Conditioning System Be Evacuated?

Generally, it is recommended to evacuate a car air conditioning system for about 30 minutes. If the system is too dirty or the pipelines have been exposed to the atmosphere for too long due to rupture, it is advisable to evacuate for one hour, preferably during warmer weather. In summary, the longer the vacuum evacuation process, the more thoroughly moisture is removed from the system as the pressure decreases, which is more beneficial for the air conditioning system. The steps for evacuating a car air conditioning system are as follows: 1. Connect the refrigeration system, manifold gauge set, and vacuum pump properly. The high and low service valves on the compressor should be slightly open, while the high and low pressure manual valves on the manifold gauge set should be closed. Remove the protective covers from the vacuum pump's suction and exhaust ports, and connect the middle hose of the manifold gauge set to the vacuum pump's inlet and outlet. 2. Open the high and low pressure manual valves on the manifold gauge set, start the vacuum pump, and observe the low-pressure gauge needle, which should display a vacuum reading. 3. After 5 minutes of operation, the low-pressure gauge should reach 33.6 kPa (absolute pressure), and the high-pressure gauge needle should drop below the zero mark. If the high-pressure gauge needle does not drop below zero, it indicates a blockage in the system. Stop the process, address the issue, and then resume evacuation. 4. After the vacuum pump has operated for 15 minutes, observe the pressure gauge. If there are no leaks in the system, the low-pressure reading should reach an absolute pressure of 13.28-20.05 kPa. 5. If this value is not achieved, close the low-pressure manual valve and observe the low-pressure gauge needle. If the needle rises, it indicates a vacuum loss. Inspect for leaks, perform necessary repairs, and then continue the evacuation process. This step is essentially the vacuum leak test method. 6. The total evacuation time should not be less than 30 minutes. After this, close the low-pressure manual valve, and you can proceed to charge the system with refrigerant.

What are the differences between the G350 and G63?

The differences between the Mercedes-Benz G63 and G350 lie in their power, appearance, positioning, and body dimensions. The standard Mercedes-Benz G-Class models include the G500 and G350, while the AMG series G-Class models consist of the G63 and G65. Below are the specific differences between the G350 and G63: Positioning: The Mercedes-Benz G350 is the standard version of the G-Class, whereas the Mercedes-Benz G63 belongs to the AMG lineup, which represents high performance. Appearance: The G350 is the standard G-Class with a horizontal grille design, while the G63, as an AMG model, features numerous AMG badges and a vertical grille design. Power: The Mercedes-Benz G350 is equipped with a 2.0T engine, delivering a maximum horsepower of 258 HP and a peak torque of 370 Nm, with a 0-100 km/h acceleration time of 8.1 seconds. The G63, on the other hand, boasts a 4.0T V8 engine paired with a 9-speed automatic transmission, producing a maximum horsepower of 585 HP and a peak torque of 850 Nm, achieving a 0-100 km/h acceleration in just 4.5 seconds. Body Dimensions: The Mercedes-Benz G350 measures 4866 mm in length, 1931 mm in width, 1975 mm in height, and has a wheelbase of 2890 mm. The G63 is slightly larger, with a length of 4870 mm, width of 1984 mm, height of 1979 mm, and the same wheelbase of 2890 mm. AMG is Mercedes-Benz's official tuning division. Models modified by AMG receive significant upgrades in power, configuration, interior, and other aspects, particularly in terms of performance. Essentially, AMG-modified Mercedes-Benz vehicles can be considered high-performance versions. The Mercedes-Benz G-Class has a profound historical background, having served the German military during World War II. Its design is simple and classic, with clean lines that embody the characteristics of an off-road vehicle. The interior offers spacious and comfortable seating, especially in the front row. However, drawbacks include poor fuel economy, generally high fuel consumption, expensive maintenance costs, and a limited number of service centers, leading to higher ownership costs.

What Do Torque and Power Mean?

Torque is a special type of moment that causes an object to rotate. The torque of an engine refers to the moment output from the crankshaft end. Under constant power conditions, it has an inverse relationship with engine speed: the faster the speed, the smaller the torque, and vice versa. This reflects the vehicle's load capacity within a certain range. External torque is called torque or external couple moment, while internal torque is called internal couple moment or simply torque. Power refers to the amount of work done by an object per unit time, meaning power is a physical quantity that describes how quickly work is performed. For a given amount of work, the shorter the time taken, the greater the power value.
