It depends on how you manage the car. For older vehicles or cars you often drive, consider repairing the bad CV axle after 3 to 4 months. Some pro technicians would tell you to manage the bad CV axle for 2 months extra; that's not ideal for every vehicle.  How long the CV axle lasts before it gets dangerous also depends on the initial condition of the vehicle's axles and the terrain you ply often. You don’t want to endanger your life by what technicians say knowing your vehicle can't hold up. We recommend you go for a CV axle replacement after 4 months of experiencing the common bad CV axle symptoms. If you feel your vehicle can hold up a little longer, try not to exceed 5 months or a max of 6 months.
