The Reason behind Better Driving

Building automobiles involves complicated procedures as auto parts must be well-coordinated with each other to perform the required functions for a vehicle. For instance, the powertrain or drivetrain is composed of essential car components that support the structure of an entire vehicle. One of these components is the axle assembly. Without it, the performance of other powertrain parts is likely to be affected.

The axle assembly is responsible for transferring the rotational force from the transmission to a vehicle’s wheels. The assembly, which includes a CV-joint or constant velocity and axle shaft, must be strong enough because it supports the weight of a vehicle and its contents. It also assures that the wheels’ position is perfectly aligned with the vehicle’s body. On the other hand, the CV-joint transmits power at a continuous rotational speed. Although it involves power transmission, the CV performs the process without any recognizable increase in the produced friction. Just like other vehicle components, the joint is delicate and needs the protection of the device called the CV boot. The CV boot shields the joint against external elements like dust or dirt.

Normally, the axle assembly is used on high-performance rear-wheel drive, front-drive, and even on four-wheel drive vehicles. These automobiles are often exposed to damaging road conditions. At times, a vehicle has to traverse rough terrains, which test the performance and durability of the axle assembly. Consequently, the powertrain components may become defective. A sign of a defective axle assembly is a grinding sound while driving. This problem is usually solved through flushing, which gets rid of the contaminants accumulated in the assembly. Applying lubricants on a regular basis also does the trick. However, these do not completely restore the ideal function of the components. Therefore, an entire axle assembly replacement is a better option.
