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. The steel rod you see running from the wheels to the transmission gears is what is referred to as the axle. The axle is what enables the car to keep moving. 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 can tell when the axle malfunction due to the noises it makes which can be popping, grinding or even clicking sounds. There may be vibrations too which will be felt through the floorboards and also the steering wheel. You should take the vehicle to the mechanic immediately instead of pushing it until it breaks.
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. The drive axles you should know about are the three-quarter, semi-floating also full-floating. A semi-floating axle is commonly used for passenger vehicles and also light trucks. It can bear a lot of weight but it is also vulnerable to shearing, compression and also tension. Full-floating axle is more expensive and heavier and it can support larger loads. The three-quarter floating axle is just cross between the two but the price is higher than what you would pay for a semi-floating axle. In order to make a good pick of the axle you should figure out whether the vehicle will be more suited by a one-piece axle or a two-piece.
One piece axles are considered more superior than the alternative. Given their durability, you can be sure that they will last much longer. Thus, they will not be breaking down a few weeks after you have had them installed. A lot of people are attracted to the two-piece axles because of the low cost but in the long run, they will prove to be more costly than the one-piece axles. If you have decided to buy the one-piece axles you should get one with tapered bearing. They are more durable which means they will hold their ground much longer compared to the roller bearings.
