A broken axle is a serious problem for any car owner, and the fact that it usually occurs on poor quality roads, which are usually rural roads, means that you can often be stranded hours away from any assistance.
There are things which you can do which will help you to avoid this happening to you:
Firstly, you need to understand the roads you’re driving on and what your vehicle can handle. It is no use driving a two wheel drive vehicle on a road which is very bumpy, as it will almost definitely cause your axle to break.
Secondly, you need to do a vehicle check before you reach a road where your axle will be tested, checking to make sure that the suspension, tyres, and wheel alignment are all well maintained and optimised for the conditions, and will help to absorb the physical stress the vehicle will experience.
