The number of CV joints on a car depends on whether it is a front-wheel drive, four-wheel drive, or all-wheel drive vehicle.
According to the reference, all front-wheel drive vehicles contain four CV joints. These CV joints are located at either end of each driveshaft, connecting the transmission to the wheels. Four-wheel drive vehicles often have CV joints performing the same function for the rear wheels, in addition to the front.
CV Joint Count by Drive Type
Here's a breakdown of the common CV joint counts based on the drive type:
| Drive Type | Number of CV Joints |
|---|---|
| Front-Wheel Drive | 4 |
| Four-Wheel Drive | 4 or more |
| All-Wheel Drive | 4 or more |
Understanding CV Joints
-
CV joints, or constant velocity joints, allow the drive shafts to transmit power at a constant speed while accommodating the up-and-down movement of the suspension and the turning of the wheels.
-
A car without CV joints would not be able to efficiently transmit power to the drive wheels, especially when turning or going over bumps.
Examples
-
A standard front-wheel drive sedan like a Toyota Camry or Honda Civic will have four CV joints.
-
A four-wheel drive truck like a Ford F-150 or Jeep Wrangler is likely to have more than four CV joints, as they are needed for both the front and rear axles.
