What is an Axle?

An axle is a crucial component of your car's drivetrain system. It connects the wheels to the transmission and allows your car to move. The axle consists of two parts - the shaft and the CV joint. The CV joint is responsible for transmitting power from the transmission to the wheels, while the shaft provides support and stability.

There are a few signs that your axle may be failing. These include clicking or popping sounds when turning, vibrations while driving, and a clunking noise when shifting gears. If you notice any of these symptoms, it's essential to get your car checked out by a professional mechanic.
