Vehicles are not usually a one piece but rather a combination of many things held together by different parts and it is the axle which keeps the front lower end of any car intact. If you are wondering what that is, look at the vehicle and note the steel rod that runs all the way from the transmission gear up to the wheels. It allows any vehicle to stay in motion. In case of damage to the axle which may be brought about by breakage, stress or general wear, the vehicle will not be functioning properly. In the worst cases, the drivetrain will end up on the ground. You know your axle is not functioning properly when you hear it making grinding, popping or clicking sounds. There may be vibrations too which will be felt through the floorboards and also the steering wheel. In such a case, you should have the axle checked instead of waiting for the vehicle to stop working before you can take things seriously.
Sometimes the axle will be damaged beyond repair and that is when you have to pick a new one. However, you need to pick the best and in order to do so, you need details on what it takes to make the best pick. Start by figuring out what kind of an axle is essential for your vehicle. You can go for full, semi, or three-quarter floating drive axles. A semi-floating axle is commonly used for passenger vehicles and also light trucks. Even it can bear a lot of weight, it is easily damaged by compression, shearing and also tension. The full-floating axle comes with a lot of weight and you will have to cough up a good sum of money to procure one but do not forget of the higher amount of load it can support. For the three-quarter floating, it is a merge of the two and it is costlier than the semi-floating axle. The next thing you will have to think about is whether you should pick a two-piece axle or a one-piece.
One piece axles are considered more superior than the alternative. They are much stronger which means they will serve you for longer than the two-piece. Therefore, you can be sure that you will be using them for a long time before you have to replace them. You will pay less for the two axles but that will end up being expensive in the long run because you will have to replace them several times. If you make up your mind to buy the one piece axle you should choose one with tapered bearings. They are said to last longer compared to their counterparts which are the ones with roller bearings.
