Upper Ball Joint Replace GMC Envoy-Trailblazer. Here I replace the Upper Ball Joint in this GMC Envoy-trailblazer. You will need to jack the GMC Envoy-trailblazer up and remove the wheel.Then you can remove the nut holding the axle ,and the nut holding the upper ball joint. Will want to remove the two bolts that hold the brake line to the knuckle,and the antilock brake wire. Then you can pull the top of knuckle out and press the old ball joint out and press the new ball joint in. Then reverse the steps to tear down for reassembly. Then the GMC Envoy-trailblazer can be safe to drive again.
