1. Safety First: Ensure the vehicle is parked on a level surface, the parking brake is engaged, and the wheels are chocked.
2. Locate the CV Joint: Identify the CV joint that needs replacement. It is typically located where the driveshaft meets the wheel hub.
3. Remove the Wheel: Use a lug wrench to loosen and remove the lug nuts. Lift the vehicle with a jack and place it on jack stands to remove the wheel.
4. Disconnect the Tie Rod End: Locate the tie rod end near the CV joint. Disconnect it by removing the cotter pin and unscrewing the nut that secures it to the steering knuckle.
5. Remove the Axle Nut: Inside the wheel hub, there's an axle nut securing the axle to the hub assembly. Loosen and remove this nut.
6. Separate the Ball Joint: Identify the ball joint located near the CV joint. Use a ball joint separator tool to disconnect it by applying force until the ball joint pops out of its socket.
7. Remove the Driveshaft: Unbolt the driveshaft from the transmission side and the wheel hub side. You might need a pry bar or a hammer to help free the joints if they are stuck.
8. Remove the Old CV Joint: Slide the old CV joint off the axle. Be careful not to damage the splines on the axle.
9. Inspect the Axle: Check the axle for any damage, grooves, or wear. Replace it if necessary.
10. Install the New CV Joint: Slide the new CV joint onto the axle. Make sure it seats properly and the snap ring or circlip is engaged to hold it in place.
11. Reattach the Driveshaft: Rebolt the driveshaft to the transmission side and the wheel hub side. Tighten the bolts to the specified torque.
12. Reattach the Ball Joint: Reconnect the ball joint by inserting it back into its socket and securing it with the nut and cotter pin.
13. Reattach the Tie Rod End: Connect the tie rod end back to the steering knuckle, secure the nut, and insert a new cotter pin.
14. Replace the Wheel: Put the wheel back on and tighten the lug nuts. Lower the vehicle from the jack stands and remove them.
15. Test Drive: Take the Blazer for a short drive to ensure everything is functioning properly.
Note: It's essential to follow the specific repair instructions for your exact model and year of the Chevy Blazer. If you're not comfortable performing this repair, it's best to seek assistance from a qualified mechanic.
