What to do if the steering wheel has different turning circles left and right?

If the steering wheel has different turning circles left and right, it can be adjusted through rough adjustment, fine adjustment, and steering wheel position adjustment. Here are the relevant details: 1. Rough Adjustment: Drive the vehicle onto a four-wheel alignment machine. Under the premise that the camber angles of both wheels are basically symmetrical, adjust the adjustment nuts of the tie rods to make the lengths on both ends as equal as possible and ensure that the toe angles on both sides approach the same value symmetrically. For example, 0 degrees. If there are persistent contradictions in the above steps, it may indicate that the frame or suspension is damaged or deformed, requiring frame adjustment or part replacement. 2. Fine Adjustment: Use a 5053 diagnostic tool to check whether the angles when the steering reaches its limits on both sides are roughly symmetrical, within a range of 5 to 10 degrees. Then, locate the electronic zero point and immediately fix the steering wheel. Perform a standard or required four-wheel alignment. After completion, drive the vehicle off the alignment machine, reset the G85, and conduct a short test drive to check for any deviation. If deviation occurs, perform another alignment and make necessary compromises in the alignment values. 3. Adjusting the Steering Wheel Position: Turn off the engine, remove the airbag module, connect the 5053 tool, and set the ignition to the self-test position (alarms may sound). Position the steering wheel at the electronic zero point, then use a puller to remove the steering wheel and adjust its position. The ideal scenario is that when the 5053 tool indicates the steering angle is at zero, the steering wheel spokes are as vertical as possible. After completion, reinstall the airbag and other components, then clear any fault codes.

Can You Continue Driving with Sidewall Cracks on Tires?

If the sidewall cracking is minor or caused by normal rubber aging, the tire can still be used. However, if the cracking is severe—such as from a sharp object cut—continued use after repair poses risks, and the tire must be replaced to ensure driving safety. Common abnormal wear patterns include: 1. Excessive wear on both sides of the tire: Mainly due to underinflation or prolonged overload driving. Low pressure or heavy loads increase the tire's contact area with the ground, causing premature wear on both edges. 2. Excessive wear on one side of the tire: Primarily caused by misaligned front wheels. When the camber angle is too large, the outer edge wears prematurely; if too small or absent, the inner edge wears prematurely.

Will points be deducted if a car does not have a fire extinguisher?

In China, private cars are not required by law to be equipped with a car fire extinguisher, so no points will be deducted. However, medium-sized (and above) passenger vehicles and hazardous goods transport vehicles must be equipped with a fire extinguisher and firefighting equipment that are within their validity period. The fire extinguisher should be securely installed on the vehicle body and easily accessible. Violators will be given a warning or fined between 20-200 yuan. Here are the relevant details: 1. Fire extinguisher selection standards: According to national regulations, the minimum capacity for a car fire extinguisher is one kilogram. As a car owner, when purchasing a car fire extinguisher, you can choose one between 1-3 kilograms. Additionally, since the storage conditions for fire extinguishers in cars are not ideal, it is best to choose a dry powder or water-based fire extinguisher. 2. Usage standards for dry powder fire extinguishers: (1) Before use, the fire extinguisher should be shaken thoroughly several times to ensure the dry powder inside is loosened. (2) Pull out the safety pin and hold the nozzle with your hand (for tube-less fire extinguishers, support the bottom of the bottle with your hand) and aim the nozzle at the base of the flame. (3) Press the handle of the fire extinguisher firmly, and the dry powder will be discharged from the nozzle.
