How do you change the lower ball joints on an 2004 envoy
If they are the original ball joints they can't be lubed.
you have to remove the spindle and press the old ones off
You change the control arms, upper and lower. The ball joints are manufactured into the control arms.
Each tire has two ball joints. If they break you will lose control of the steering and crash.
all the ball joints are self lubricated, meaning no grease fittings, you cannot grease them or the steering joints, you can grease the front and back u joints on the drive shafts,but that is all.
The lower ball joints have to be pressed out. The upper ball joints are part of the control arm, so the complete upper assembly has to be replaced.
