How to Determine if the Control Arm is Damaged?

If it affects the balance and causes the vehicle to pull to one side, it indicates that the control arm is damaged. Additionally, if there is increased wear space affecting directional control, the pulling issue also impacts safety, and a comprehensive inspection at a 4S shop is recommended. The control arm, also known as the swing arm, functions to balance and support. Below is an introduction to the control arm: 1. When driving on uneven roads, the tires move up and down, which is facilitated by the swinging motion of the control arm. The tires are mounted on the wheel hub, which is connected to the control arm via a ball joint. 2. The working principle of the control arm is essentially that of a universal joint, allowing connected movement even when the relative positions of the driving and driven sides change. For example, during steering, the shock absorber is compressed, causing the A-arm to swing upward. 3. The control arm is connected to the subframe through a front subframe connection point hinge sleeve. The forces and impacts received by the wheels are transmitted to the vehicle body through this hinge sleeve. The front subframe connection point hinge sleeve is a potential location for cracking, meaning that in the event of an 'axle break' accident, it is highly likely to occur at this hinge sleeve.

How much does it cost to repair a fallen reversing radar dot?

Repairing a fallen reversing radar dot costs around 3000. Here are the details: Monitoring radar: When you find the reversing radar is not working, first check if the wiring connection at the bumper is intact, then check if the reversing light turns on when shifting to reverse gear. If it doesn't, check if the reversing light connection switch is broken. Then you can check if the computer displays any fault codes. If none of these are issues, proceed to check if the reversing radar itself is malfunctioning. How reversing radar works: During reversing, the reversing radar uses ultrasonic principles. The sensor mounted on the rear bumper sends ultrasonic waves that reflect off obstacles, calculates the actual distance between the vehicle and the obstacle, and then alerts the driver, making parking or reversing easier and safer.

How Many Points Are Deducted for Reversing?

Reversing deducts 3 points. Here are the details: Reason: Reversing on the road is a relatively serious violation of traffic rules, which not only poses a threat to the safety of others but also to your own safety. Therefore, certain legal responsibilities must be borne. Typically, this results in a fine and a deduction of 3 points. If you disagree with the penalty, you can apply for a review. If you are dissatisfied with the review result, you can apply for administrative reconsideration. Regulation: When reversing a motor vehicle, the driver should check the situation behind the vehicle and confirm it is safe before reversing. Reversing is not allowed at railway crossings, intersections, one-way roads, bridges, sharp turns, steep slopes, or in tunnels.

Can You Use First Gear for a U-Turn in Subject Three?

Subject Three allows the use of first gear for a U-turn, which is one of the test items in Subject Three. It requires the examinee to control the speed, correctly use the gears, and choose an appropriate location for the U-turn. In the Subject Three test, there are no specific requirements for the gear selection. Generally, you can choose to use first or second gear for the U-turn. First gear is the safest option, but you can also use second gear for the U-turn if safety is ensured. The specific operation method for a U-turn in Subject Three is as follows: 1. When the voice prompt announces "Please make a U-turn ahead," the examinee should turn on the left turn signal, observe the surroundings, safely yield to oncoming vehicles, and must use a gear below second gear for the U-turn, reducing the vehicle speed to below 20 kilometers per hour. 2. Pay attention to yielding to vehicles coming from both directions, and do not affect the normal driving of other vehicles. Before making the U-turn, you can stop and wait for the right moment to complete the U-turn in one go, avoiding improper operation or stopping midway. If there is a crosswalk during the U-turn, the vehicle must pass the crosswalk before making the U-turn. Do not make the U-turn on the crosswalk, and do not stop and wait on the crosswalk.

Should a reversing vehicle yield to a straight-moving vehicle or vice versa?

Reversing vehicles should yield to straight-moving vehicles. Here are the details: Reason: The so-called "turning vehicles yield to straight-moving vehicles" means that, in principle, vehicles turning left (or right) should give way to straight-moving vehicles. This is because straight-moving vehicles generally travel at higher speeds and there is heavier traffic in straight-moving lanes, whereas turning vehicles move relatively slower and there is lighter traffic in turning lanes. Therefore, the rule "turning vehicles yield to straight-moving vehicles" helps reduce congestion and traffic accidents. The same principle applies to reversing vehicles. Right-turning vehicles yield to left-turning vehicles: The terms "right turn" and "left turn" are relative to oncoming vehicles. When one vehicle turns right and another turns left into the same intersection, the right-turning vehicle must yield to the left-turning vehicle.

What are the reasons for a reversing radar having display but no sound?

If a reversing radar has display but no sound, it may be due to damage to the reversing radar. Here are the specific details: Reversing radar not sounding: First, check whether the power cord of the main unit is properly connected and whether there is current; then check if the main unit wire of the radar is loose. If neither of these is the issue, the problem may lie with the radar itself. Regarding the reversing radar: The first possibility to consider is a damaged buzzer, in which case you need to purchase and install a new buzzer; also, check if the car has undergone any recent modifications. If so, the wiring of the reversing radar may have been damaged during the modification process, and the car should be taken to the original repair shop or a 4S shop for inspection. Bumper wiring issue: Check if the wiring connection at the bumper is intact; check whether the reversing light turns on when the reverse gear is engaged. If not, inspect whether the connection switch of the reversing light is damaged.

Can I leave if there is no trace after hitting the rear car while reversing?

You cannot leave if there is no trace after hitting the rear car while reversing. Here are the details: The reversing party: If a collision occurs between a reversing vehicle and a vehicle moving straight, the reversing party is generally held fully responsible. Dispute: If there is a dispute over liability determination, you can call the police, and the traffic management department will issue a liability determination certificate. Below is extended information on the relevant content: One-party liability: If a road traffic accident is caused by the fault of one party, that party bears full responsibility. Two-party or multi-party liability: If a road traffic accident occurs due to the fault of two or more parties, they shall bear primary, equal, or secondary responsibility based on their actions' role in the accident and the severity of their faults. Accidental traffic accident: If no party is at fault for causing the road traffic accident, it is considered a traffic accident, and no party bears responsibility. If one party intentionally causes a road traffic accident, the other party bears no responsibility.
