How do you replace lower ball joint on 1996 Honda civic?

Not so easy.

This is pressed into the lower control arm.

So :

• Jack and support car
• Remove lower ball joint to upright nut.
• Separate ball joint from upright. Usually with a hammer and suspension fork.
• In some cases there is a spot weld that needs to be ground off in place of the snap ring.
• Remove the snap ring that retains the joint into the lower control arm.
• Use your portable ball joint and suspension press to remove and install the replacement joint.
• Assembly is reverse of disassembly.
