CV Axle Shaft Assembly

A CV Axle Shaft Assembly transfers power from the transmission or differential to the drive wheels, allowing smooth acceleration while the suspension moves and the wheels turn.
Our replacement CV axles and halfshafts are designed for reliable drivetrain performance and direct vehicle fitment.

Experiencing These Driving Issues? Signs your CV axle or CV joint may need replacement:

  • Clicking noise when turning
  • Vibration during acceleration
  • Grease leaking near the wheel
  • Steering or drivetrain vibration

Replacing the CV Axle Shaft Assembly helps restore smooth power delivery.

What Is a CV Axle Shaft Assembly?

A CV Axle Shaft Assembly is a key drivetrain component that transfers engine power from the transmission or differential directly to the drive wheels.
In most passenger vehicles such as sedans, crossovers, and SUVs, the axle is commonly called a halfshaft because each side of the vehicle uses one axle shaft to drive the wheel. Together, the left and right shafts form the vehicle’s drive axle system.

During repairs or parts searches, you may hear several different names referring to the same component, including:
CV Axle, CV Halfshaft, Drive Axle Shaft, Front / Rear Drive Axle
These terms are often used interchangeably in service manuals and auto repair shops.

A simple way to recognize a CV axle:
it is the shaft connected to the wheel hub that has rubber boots on both ends and can move with the suspension while the wheels steer left and right.Because of this flexibility, the Constant Velocity (CV) joint design allows smooth power delivery even when the suspension moves or the wheels turn.

Main Parts of a CV Axle Shaft

A CV axle shaft assembly is made up of several key components that allow power to transfer smoothly from the drivetrain to the wheels.

Main components include:

  • Inner CV Joint – Connects to the transmission or differential
  • Axle Shaft (Halfshaft) – Transfers torque between both joints
  • Outer CV Joint – Connects to the wheel hub and allows steering movement
  • CV Boots – Protect the joints and keep grease sealed inside

Why Are CV Axles Different on the Left and Right Side?

Most vehicles use two CV axles on the front drivetrain — one for the driver side (left) and one for the passenger side (right). Because the transmission is not perfectly centered, the two axles are often different in length and joint design.

For this reason, replacement axles are typically sold as:

  • Front Left (Driver Side)
  • Front Right (Passenger Side)

Vehicles with AWD or independent rear suspension may also have rear CV axles, which are also installed on the left and right sides.

Always confirm the correct position and vehicle fitment before purchasing.
