Should You Replace One or Both Half Shafts When They're Broken?

[LaBrantley]

You only need to replace one half shaft when it's broken. Below is a detailed introduction about half shafts: Introduction to the Function of Half Shafts: Automotive half shafts, also known as drive shafts, are solid shafts that connect the differential to the drive wheels to transmit torque. If a half shaft is broken, it will affect the normal driving of the car, so timely repair and replacement are essential. Based on the force they bear, half shafts are categorized into full-floating half shafts and semi-floating half shafts. Impact of Half Shaft Damage: If a car's half shaft is damaged, it can cause the vehicle to lose balance while driving, resulting in steering wheel vibrations. Strange noises may also occur, indicating a possible half shaft failure. Uneven tire wear may appear, leading to tire abrasion or cracks. Under safe driving conditions, the car may experience shaking, wobbling, or pulling to one side. If the drive shaft is severely damaged, the tire may even detach while driving, leading to unpredictable traffic accidents. Specific Symptoms of Half Shaft Damage: Metal friction sounds or metal collision noises from the vehicle are early signs of half shaft damage. You may feel intense body shaking while driving; there may be abnormal noises, such as metal friction sounds, when turning the steering wheel; and strong vibrations can be felt at high speeds.
