Why is the rear wheel of a scooter wobbling?

For a wobbling rear wheel, check the following aspects separately: whether the tire pressure is insufficient, whether the rear axle nut is loose, whether the tire has bulges or is improperly installed and twisted, whether the rear shock absorber is too soft, whether the rear wheel bearings are damaged, and whether the rear rim is deformed. The related explanations are as follows: 1. Inspection items: If it is a pedal-assist scooter, also check whether the engine mounting bracket bushings are aged and loose. If it is a underbone or straddle-type scooter, check whether the rear swing arm screws are loose or the swing arm bushings have excessive clearance. 2. Hand test: For a scooter's rear wheel, you can feel slight front-to-back movement by gently pulling it with your hand (this is actually not the wheel's looseness), but there should be no side-to-side movement. If the rear wheel appears to wobble side to side, check whether the tire has bulges or is twisted. Aluminum wheels generally do not deform.

Can a Car Still Drive After Being Flooded?

Whether a car can still drive after being flooded depends on the extent of the flooding. If the water has not submerged the wheels, the car can be driven normally. However, if the water level is too high, it may affect the car's electrical circuits, making it unsafe to drive. If the water has reached the hood of the car, it is best to inspect the vehicle for damage and avoid starting it. If the car stalls after being flooded, do not attempt to restart it. Restarting the engine may cause it to stall again, potentially leading to further damage, which could affect insurance claims later on. After a car is flooded, it is crucial to notify the insurance company immediately and describe the situation. The insurance company will then send someone to inspect the vehicle and assess the damage. In cases of extreme weather where the insurance company cannot arrive promptly, the driver should document the damage themselves. It is advisable to take photos from multiple angles using a camera or smartphone to provide evidence for the insurance company's assessment of the damage.

What is the reason why the Nissan Qashqai suddenly fails to start but has power?

The reasons why the Nissan Qashqai suddenly fails to start but has power are as follows: The engine starts by the battery current pushing the spark plug to ignite. There may be two main reasons causing the engine to suddenly fail to start. First, it is very likely due to battery rust or leakage. Second, it could be caused by the engine spark plug getting damp on rainy days. Maintenance methods: Check the battery fluid level every one to two months to ensure it is sufficient. If the fluid level is between the upper and lower two marked lines, it is considered appropriate. Also, check the fluid level difference in each cell. If the fluid level is insufficient, unscrew the cap on the battery and add distilled water to replenish the fluid level. Additionally, inspect the battery terminals and use a wire brush to remove any accumulated dirt. If the terminal clamps are severely dirty, use sandpaper to scrape off the dirt along the inner wall. If the spark plug is damp, remove it and use a lighter to dry it to quickly evaporate the moisture on it.

What Causes Transmission Control Module Failure?

Transmission control module (TCM) failure indicates a valve body issue, which can typically be resolved by cleaning the filter screen. Below are specific details about transmissions: 1. Overview: A device that alters speed ratios and direction of motion. Used in automobiles, tractors, ships, machine tools, and various machinery to modify torque, speed, and direction transmitted from the driving shaft to the driven shaft under different working conditions. Gear-driven transmissions generally consist of a housing and multiple gear pairs. 2. Functions: Changes vehicle driving force and speed (gear shifting) while maintaining constant engine RPM and torque; enables reverse movement (direction change); allows engine idling without stalling (neutral gear). Based on transmission types, gear transmissions can be categorized into three types: dual-shaft, triple-shaft, and compound configurations. Dual-shaft transmissions have two main shafts (excluding reverse gear shaft) with only one gear pair for speed reduction. Triple-shaft transmissions feature three main shafts (input shaft, countershaft, output shaft) requiring two gear pairs for speed reduction. Compound configurations combine two transmissions in series or parallel to achieve more gear positions with fewer gears.

Do Honda Cars Have a Particulate Filter?

Honda has a particulate filter. A particulate filter is a ceramic filter installed in the exhaust system of diesel engines, which captures particulate emissions before they enter the atmosphere. Function of the Particulate Filter: The particulate filter can reduce soot produced by diesel engines by more than 90%, and the captured particulate emissions are subsequently burned off during vehicle operation. Principle of the Particulate Filter: The diesel particulate filter is coated with metals such as platinum, rhodium, and palladium. The black smoke containing carbon particles emitted by the diesel engine enters the engine's exhaust particulate filter through a dedicated pipe. After passing through the densely arranged bag-type filters inside, the carbon particles are adsorbed onto the filter made of metal fiber felt. When the amount of adsorbed particles reaches a certain level, the burner at the end automatically ignites and burns, turning the adsorbed carbon particles into harmless carbon dioxide that is then released.

Do I Need to Retake the Written Test When Switching from Manual to Automatic Transmission?

Switching from manual to automatic transmission does not require retaking the written test (Subject 1). Here are the details: Reason: Because the C1 driver's license covers the C2 vehicle type, and you have already passed the Subject 1 test, there is no need to retake it after switching to a C2 license. You can apply to your driving school to change your license type to C2, and the school will handle the registration change with the vehicle management office. C1 License Test Content: There are three test items in total, which are: Traffic regulations and related knowledge, field driving, and road driving. The traffic regulations and related knowledge test is commonly referred to as Subject 1; the field driving test is Subject 2; and the road driving test, also known as Subject 3, is divided into two parts: road driving skills test and safe driving knowledge test, commonly referred to as the road test and Subject 4.
