Can the car still be driven after the front axle is broken and repaired?

There will be an impact if the front axle of the car is broken and then repaired. The following is an introduction to the front axle of the car: 1. Composition: The finished product of the front axle consists of an I-beam, steering knuckle, steering tie rod, wheel hub, brake and other parts. The I-beam is integrally forged and shaped, and its cross-section is "I" shaped, hence the name "I-beam". 2. Introduction: One of the main structures of the car, the finished product is called the "front axle assembly". It uses the swing of the steering knuckle to realize the steering of the car, so it is also called the steering axle. Located at the front of the car, it is also called the "front axle". To ensure the safe driving of the vehicle, the front axle is equipped with an appropriate front wheel alignment angle.
A broken axle can be a minor or major issue. I've seen many car owners forcibly weld the axle back together and continue driving, only for it to snap again on the highway, nearly causing a disaster. The axle bears the dual pressure of the vehicle's weight and steering forces, and the strength of a weld is typically only about 70% of the original part. The fracture point becomes a structural weak spot, making it particularly prone to re-breaking during turns or when going over speed bumps. Repair shops can usually only perform temporary welds, but the internal metallurgical structure is already compromised—like a bone that's been set with a cast, which is far inferior to the original. I strongly recommend replacing the entire front axle assembly rather than risking your life to save a few thousand bucks. After repairs, a four-wheel alignment and dynamic balance test are essential; otherwise, the car will shake noticeably while driving.
My old Jetta had its right axle broken last year. The mechanic spent a long time measuring with a welding torch, but finally said even if welded back, it could only be used as a grocery getter. The axle has precise heat-treated structures inside—once broken, even if welded, it loses toughness and might suddenly snap under hard braking. I ended up gritting my teeth and replaced the entire axle assembly, along with the suspension control arm, to feel safe. After all, the axle is crucial for steering control; if it breaks again on the road, the steering wheel could lock up instantly. Also, note that a bent axle can cause uneven tire wear, wearing out a tire in just two or three months.
