What are CV joints in a car?

Published in Car Mechanics 2 mins read

CV joints, or constant velocity joints, are crucial components in a vehicle's drivetrain. They connect your vehicle's transmission to its wheels. They allow the wheels to move independently while still receiving power from the engine.

Understanding CV Joints

Here's a more detailed look at CV joints:

  • CV joints are part of the driveshaft.
  • They are primarily found on front-wheel drive vehicles, but are also used in rear- and four-wheel drive vehicles as well.

Why are CV Joints Important?

CV joints play a vital role in a car's performance:

  • Power Transfer: They ensure that power is transferred to the wheels smoothly and efficiently, even when the wheels are turning at different angles due to steering or suspension movement.
  • Flexibility: They provide the flexibility needed for the wheels to move up and down and side to side, all while keeping the drivetrain connected.
  • Durability: They are designed to withstand the stresses of driving, including bumps, potholes, and other road hazards.

Types of Vehicles Using CV Joints

CV Joints can be found in the following types of vehicles:

  • Front-Wheel Drive Vehicles
  • Rear-Wheel Drive Vehicles
  • Four-Wheel Drive Vehicles
