Why does the car make a rattling noise when accelerating?

Why is there abnormal noise when steering?

Abnormal noise when turning the steering wheel may be caused by a faulty airbag clock spring inside the steering wheel or aging of the steering tie rod ball joint. Reasons for abnormal noise when steering: Loosening or damage of the stabilizer bar bushings. Loose or damaged stabilizer bar bushings not only cause noise when turning but also produce sounds when driving on uneven roads. Loose stabilizer bar bushings can be fixed by adding shims, while damaged ones must be replaced. Consequences of aging ball joints in cars: Damaged ball joints can cause slight displacement of the suspension, leading to errors in wheel alignment data, which may result in uneven tire wear or even steering deviation. It is advisable to address the issue at a nearby repair shop as soon as possible to avoid greater losses. Note that after fixing the chassis issue, a wheel alignment must be performed again; otherwise, the problem will persist. If the ball joint is excessively loose, it may cause the connected rods and arms to break or even detach under load impact.

Can You Turn Right on a Red Light?

There are two scenarios for turning right on a red light: 1. If it's a circular traffic signal, vehicles in the right-turn lane can proceed to turn right when the light is red, but they must not obstruct other vehicles with the right of way, as well as pedestrians and vehicles on the rear and right-side roads. 2. If it's an arrow-shaped right-turn signal, turning right is not allowed when the light is red. Some special intersections may have additional signs, and the instructions on these signs take precedence—they may prohibit right turns or allow them. If you're concerned about running a red light, you can check for traffic violations online, which are usually available for query within 3 to 5 days after the violation. Simply enter your license plate number and the last six digits of your engine number to check. Any fines must be paid within 15 days, otherwise a 3% late fee will accrue daily, up to a maximum of double the original fine. Additionally, unresolved violations can affect your annual vehicle inspection.

What to Do When You Lose Your Car Keys?

If you lose your car keys, the safest approach is to take the spare key to a 4S dealership and have the staff rematch the engine immobilizer system with a new key. For vehicles without an engine immobilizer function, the secure solution is to replace the entire lock cylinder and keys. Every car comes with a spare key, so you can continue using it if the original is lost, but be mindful of property security. With rapid advancements in electronic technology, many modern vehicles now feature transponder chip anti-theft technology integrated with the ECU engine control unit. When the owner starts the vehicle using a valid transponder key, the anti-theft system automatically verifies whether the key's ID code matches the one stored in the vehicle's security system. If the ID codes match perfectly, the system deactivates the immobilizer, allowing the engine to start normally.

How to Determine if the Clutch Master Cylinder is Faulty?

Methods to determine if the clutch master cylinder is faulty: 1. Check for oil stains on the exterior of the master cylinder and slave cylinder, as oil stains indicate leakage; 2. Observe the extension length of the slave cylinder push rod when depressing the clutch pedal. If the extension is insufficient, it suggests pressure loss, or if the push rod retracts when extended, it also indicates pressure loss. The clutch master cylinder is the component connected to the clutch pedal and linked to the clutch booster via a hydraulic line. Its function is to collect pedal travel information and, with the booster's assistance, disengage the clutch. When the driver presses the clutch pedal, the push rod moves the master cylinder piston, increasing hydraulic pressure, which travels through the hose to the slave cylinder, forcing the slave cylinder push rod to disengage and push the release bearing forward. When the driver releases the clutch pedal, the hydraulic pressure is relieved, and the release fork gradually returns to its original position under the action of the return spring, causing the clutch to re-engage.

Is the Liability Split 70-30 When a Left-Turning Vehicle Is Hit by a Straight-Going Vehicle While Almost Completing the Turn?

When a left-turning vehicle is hit by a straight-going vehicle while almost completing the turn, the liability is not always split 70-30, as traffic accidents can vary greatly. If the accident scenario is not entirely clear, the responsibility will ultimately be determined by the traffic police after investigating the actual circumstances. Following an on-site inspection, for complex traffic accidents, the traffic management department of the public security authority will issue a traffic accident liability determination report based on the actual situation. Traffic regulations stipulate: 1. When a straight-going vehicle is driving on the main road and a right-turning vehicle is preparing to merge from the auxiliary road, the straight-going vehicle on the main road has the right of way; 2. When a motor vehicle approaches an intersection without traffic signals, police direction, or traffic signs and markings, it should stop and observe before proceeding, then determine the right of way according to the following rules: yield to vehicles coming from the right, turning vehicles yield to straight-going vehicles, and right-turning vehicles yield to left-turning vehicles when traveling in opposite directions.

How to Determine if the Cylinder Head Gasket is Blown?

Methods to determine if the cylinder head gasket is blown: 1. Overheating; 2. No water leakage but water shortage; 3. Water mixing in the radiator, with rattling noises from the engine cylinders; 4. Deformation, elongation, or loosening of cylinder head bolts and nuts. When nuts or bolts loosen, the pressure on the joint surface becomes uneven, and high-pressure, high-temperature gases along with rapidly flowing coolant and lubricating oil continuously erode the cylinder head gasket, leading to gasket failure; 5. Abnormal operation of the engine cooling system, causing the engine to operate at high temperatures for extended periods, resulting in excessive heat exposure to the cylinder head gasket, loss of elasticity, and eventual erosion, leading to gasket damage and failure; 6. Use of substandard materials when selecting the cylinder head gasket; 7. Deformation of the joint surface between the cylinder block and cylinder head, causing the cylinder head gasket to be unevenly compressed, leading to air leakage and gasket burn-out; 8. Improper driving techniques, such as frequently slamming the accelerator, sudden acceleration, and high-speed operation, which increase pressure and accelerate gasket erosion.
