A CV joint, also referred to as a constant-velocity joint, is one of the components of the drive shaft that allows you to steer the wheels while traveling. If the CV joint begins to malfunction, you will not be able to operate your vehicle properly, which might lead to an accident. Replacing a worn CV joint on your 1998 Chevrolet Blazer can take up to an hour as it requires you to raise the vehicle to access the CV joint.

Step 1

Place the jack under the side of the Blazer on which you will be replacing the CV joint, and raise the truck to a comfortable level.

Step 2

Support the lower control arm under the wheel with a floor jack. Remove the wheel nuts and wheel cover. Remove the wheel from the Blazer, and set it aside.

Step 3

Remove the lower cotter pin with a socket wrench. Loosen, but do not remove, the stud nut. Loosen the CV joint with a CV joint removal tool. The removal tool for the 1998 Blazer is a J-9519-30 tool, which can be bought directly from Chevrolet or through online automotive shops. Once you have loosened the CV joint, remove the nut and joint from the vehicle. If you have difficulty removing the CV joint, rotate the steering wheel as far inward as you can.

Step 4

Install the replacement CV joint on the Blazer by securing it with the bolt and cotter pin. Rotate the steering wheel to make sure the ball joint is installed properly.

Step 5

Reinstall the wheel, and lower the Blazer.
