Is the replacement of the Yuanbao beam considered a major accident
The replacement of the yuanbao beam usually falls within the category of major accidents , as the yuanbao beam is a core structural component of the vehicle chassis. It only gets damaged or needs to be replaced in cases of severe collisions or significant impacts on the chassis, which directly indicates that the vehicle has experienced a high-intensity accident.
Youdaoplaceholder0 The function and replacement reasons of the yuanbao beam
The Yuanbao beam (subframe) is a key component connecting the front axle and the rear frame. Its main functions include:
Support core components such as the engine and transmission, and enhance the overall strength of the chassis.
Protect the engine oil pan from direct impact and enhance driving stability.
Due to its solid position, ordinary collisions (such as minor rear-end collisions) usually do not cause damage. Only severe accidents (such as high-speed impacts, chassis compression or rollover) may cause deformation or fracture, and thus require replacement.
Youdaoplaceholder0 Accident vehicle determination criteria and impacts
In the assessment of vehicle accident grades, the replacement of the Yuanbao beam is one of the core bases for judging major accidents:
Youdaoplaceholder0 Definition of accident vehicle : A vehicle is classified as an accident vehicle if it meets any of the following conditions: the burning area exceeds 0.5 square meters, water immersion exceeds half of the vehicle body and enters the driver's cabin, airbags deploy, or the main frame is cut or welded. The replacement of the Yuanbao beam is usually accompanied by these situations, as its damage often leads to deformation of the main frame.
Youdaoplaceholder0 safety risk : After replacement, the body strength will decrease, affecting driving stability and collision safety. Even if repaired, it is difficult to restore the original factory performance.
Youdaoplaceholder0 Exception : In a few cases, the replacement of the yuanbao beam may be caused by abnormal noise due to aging of the rubber sleeve or improper maintenance of minor accidents, but professional detection is required to rule it out.
Youdaoplaceholder0 Car purchase and maintenance advice
Youdaoplaceholder0 Second-hand car selection : When you find the replacement record of the yuanbao beam, you should check the insurance claim report, inspect the condition of the main frame, and avoid purchasing such vehicles.
Youdaoplaceholder0 Maintenance decision : Replacing the yuanbao beam falls within the category of major overhauls and must be carried out by a professional institution, with complete maintenance records kept.
Whether replacing the Yuanbao beam is considered a major overhaul depends on the specific extent of the vehicle's damage: if only the Yuanbao beam is slightly damaged and the other parts of the chassis remain intact, it does not count as a major overhaul. If the entire chassis is damaged due to a serious accident, it is considered a major overhaul.
Youdaoplaceholder0 The core criterion for determining whether it is a major overhaul is
Whether the replacement of the Yuanbao beam (subframe) is defined as a major overhaul depends on a comprehensive assessment of the severity of the vehicle damage and the scope of the repair. It mainly falls into the following two situations:
Youdaoplaceholder0 situations that do not fall under major overhauls : When the ingot beam is only damaged due to minor bumps, local deformation or small-scale scratches, and the chassis structure, suspension system and other related components are not damaged, replacing the ingot beam is considered partial repair. This type of maintenance only requires the replacement of a single component, without the need for large-scale disassembly or adjustment of the overall structure of the chassis. It has a relatively small impact on the vehicle's handling, driving stability and core performance, and thus is not regarded as a major overhaul.
Youdaoplaceholder0 situations that fall under major overhauls : If a vehicle suffers overall damage to the beam and chassis due to a serious accident (such as a collision), and the suspension system shifts, the frame deforms, or related components (such as the engine bracket) need to be repaired simultaneously, then replacing the beam involves complex engineering. At this point, the scope of maintenance is extensive and the cost is high. It may be necessary to lift the engine or transmission and recalibrate the force balance of the chassis, which has a significant impact on the vehicle's safety and performance. Therefore, it is classified as a major overhaul.
Youdaoplaceholder0 The function and replacement impact of the yuanbao beam
The Yuanbao beam (subframe) is a key component of the chassis, responsible for connecting the suspension system with the frame, enhancing structural strength and improving driving comfort. The effects of the replacement include:
Youdaoplaceholder0 Performance aspect : If only the yuanbao beam is replaced and the quality of the new component is qualified, it usually does not affect the controllability or stability; However, if a major overhaul is caused by an accident, the vehicle may experience abnormal noises from the chassis or handling deviations during long-term driving.
The value of a used car : regardless of whether it has undergone major repairs or not, replacing the gold coin beam may cause the vehicle to be marked as an "accident car", leading to depreciation. Replacement caused by serious accidents will significantly reduce the residual value.
Youdaoplaceholder0 Maintenance decision-making suggestions
Car owners should take action based on the actual degree of damage:
Youdaoplaceholder0 Assessment of damage : Confirm the extent of damage to the yuanbao beam and the integrity of the chassis through professional inspection to avoid making judgments based solely on the surface.
Youdaoplaceholder0 Weigh the cost : Replace the gold coin beam first when it is slightly damaged; If a major overhaul is involved, the decision on whether to continue using the vehicle should be made by comprehensively considering the maintenance cost and the residual value of the vehicle.
Youdaoplaceholder0 Seek professional advice : Rely on the reports from maintenance technicians or third-party testing institutions to ensure that the maintenance plan is reasonable.
