When it comes to the performance and drivability of your vehicle, your vehicle's axle, CV joint and driveshaft components are essential. The driveshaft is a cylindrical component made from either steel or aluminum that connects the transmission to the rear differential. The driveshaft connects to the transmission through the CV joints, which are responsible for transferring the torque from the transmission to the drive wheels at a constant speed. CV joints are on the front axles on front wheel drive vehicles. CV joints allow the axle on the vehicle to bend and change, accommodating the bounce of the wheels. The axle bears the weight of the vehicle while also being strong enough to sustain the forces from braking and accelerating. Over time and through normal use, your vehicle’s axle, CV joint, and driveshaft components may require maintenance or replacement services.
