Simple Steps for Removal and Service
of ATV CV Joints
The following procedure is recommended for the removal and inspection of typical CV joint style axles found on most ATVs. These steps are for general informational purposes only and do not apply to all ATVs. Always be sure to observe good safety practices while working on heavy machinery.
- Loosen lug nuts and wheel spindle nut. Lift and block vehicle. Remove wheel nuts and wheel. Then remove the sheel spindle nut.
- Remove the nut holding the lower ball joint to the hub assembly.
- Some applications have a transverse bolt that retains the ball joint stud to the hub assembly. This should be removed
- Loosen the ball joint stud from the hub assembly with a fork, being careful not to damage the flexible seal that protects the ball joint.
- Using the leverage of a pry bar, completely separate the lower ball joint stud from the hub assembly. Push the hub assembly to one side of the lower control arm.
- Free the cv joint from the hub assembly by tapping the spindle. Be careful not to damage the spindle threads.
- Using the leverage of a pry bar, separate the axle shaft from the transmission. On some models, the axle shaft is held onto the output shaft by a cotter pin and must be removed.
- Support both ends of the axle shaft when removing it from the vehicle.
- Most typical axle shafts have two cv joints, an outboard cv joint and an inboard cv joint. Each joint is lubricated with special high temperature grease, and protected with a cv boot seal.
