Is the ball joint part of the control arm?
Ball joints are made of a bearing stud and socket that fit snugly inside a lubricated casing.

The front suspension of most cars has at least lower ball joints and in some cases upper ones as well.

What are the bearings in a steering knuckle called?
They are round (hence the name “ball”) bearings in a socket which function just like the ball and socket of a human hip. Just like the ball socket of your hip, they serve as one of the main pivot points connecting the control arms of the vehicle to the steering knuckle.
What’s the difference between upper and lower ball joints?
In non-MacPherson strut automobile suspension, the two ball joints are called the “upper ball joint” and “lower ball joint”. Lower ball joints are sometimes larger and may wear out faster, because the fore and aft loads, primarily due to braking, are higher at the bottom ball joint.
What makes up the lower ball joint on a steering wheel?
The lower ball joint is what attaches the steering knuckle and control arm together. There are two pieces which make up the lower ball joint; a socket and ball. These pieces are inside of a rubber boot that is filled with lubricant. Basically, the lower ball joint allows the wheels and tires to be connected to the vehicle and its steering assembly.
Remove the single bolt on the ABS sensor. Remove upper ball joint nut and use hammer on the stem end or spindle arm until the ball joint pops out.

What happens when a front ball joint fails?
Should a ball joint break, the wheel becomes totally free to move in any direction, which can damage the car’s fender, tire, and several suspension components, if not more.
