What causes steering wheel and body vibration?

[OLily]

It may be due to deformation or vehicle transmission system failure, excessive carbon deposits, unstable oil pressure in the fuel supply system, and other reasons. Hazards of abnormal vehicle vibration: While driving, vibration can cause the vehicle to deviate from its direction and lead to tire slippage. In severe cases, it may result in traffic accidents. Vehicle maintenance: When starting a cold engine, allow it to idle for about one and a half minutes to give it a warm-up period. Avoid lugging the engine while driving, and downshift promptly when engine vibration occurs. Protect the chassis. The chassis is the part of the vehicle closest to the ground and is highly susceptible to damage from road objects. Therefore, regularly inspect the chassis to prevent excessive damage from foreign objects.
