Keeping the ball joints lubricated on your Chevy Blazer is a great way to prolong the life of the ball joints. Ball joints have a small rubber bladder on them that holds grease to keep the moving parts inside lubricated. The maintenance of a ball joint is much easier that replacing them due to neglect. You just need the proper steps and a few tips to perform this task properly and keep your truck on the road as long as possible.

Jack up the front of the vehicle and secure it with jack stands.
Locate the four ball joints. There will be an upper and lower on each side of the truck. The ball joints will be at the very edge of the upper and lower control arms, right by the wheel. They have a flat top with a metal nipple coming from it, a rubber bladder in the middle and a stud with a nut on it on the bottom.
Press the hose end of the grease gun over the nipple.
Pump the handle of the grease gun to begin filling the bladder with grease. Stop filling the bladder when you see a small amount of grease seeping from the bladder edges.
Repeat steps 2 through 4 for the three remaining ball joints.
Remove the jack stands, lower the vehicle and test-drive it. Listen for any squeaking when hitting bumps. This is a sign of low grease levels or a faulty ball joint.
Tips and warnings
- Always inspect the rubber bladder for any cracks or breakage. Replace the ball joint if this exists.
