A broken car axle can cause the vehicle to sputter, make a clunking noise or create excessive vibration during acceleration. If the broken axle is not repaired it eventually prevents the car from moving.
Car owners who suspect that an axle on their car may be damaged or broken should take it to a certified mechanic immediately for an evaluation and repairs. If not repaired, a broken axle can cause further damage to the vehicle. There are several things that can break an axle including overloading, hitting a hard bump in the road, age and having bad carrier bearing on the vehicle.
