Symptoms of Bad Ball Joints

Posted 8/6/2019

What you need to know of your vehicle's suspension

The front suspension of your vehicle is a rather extraordinary system. An intricate assembly of control connections and wheel hubs, the front suspension not only enables your front wheels to move up and down individually of one another to give you a stable ride, it also makes both wheels turn left or right concurrently so that you can make your vehicle go where you need to go.


Although there are numerous sorts of front suspensions, such as the upper and lower control arm type and the MacPherson strut-type, they all share a basic component that allows them to do what they are produced to do: the ball joint. If a ball joint fails, it can have frightful consequences.


Today’s vehicles feature a front suspension system that uses upper and lower control arms to join the wheel hub to your vehicle. The wheel hubs, on which your wheels and tires are attached, are mounted to the outer ends of each control arm and persist commonly vertical as they move up and down with the rotating of the control arms. The hubs are also joined to your steering system and must be able to swivel left and right at any point in their up and down movement.


Ball joints are the crucial components that connect your wheel hubs to the control arms. They provide universal pivoting movement between the wheel hubs and control arms to give you a reliable, soft ride and allow you to precisely regulate your vehicle.


Their actual lifespan will depend on your driving manners, road circumstances and exposure to road splash and salt. As the ball and socket wear mutually, the normally close tolerance between them will expand and the ball joint will become wobbly over time.

Wear indicators incorporate mobile grease fitting. When a neckband of the grease fitting is level with or below the bottom of the ball joint housing, the ball joint is worn and should be repaired.


Other types have a wear indicator pin protruding through a hole in the bottom of the ball joint. As long as the pin is visible, the ball joint is OK. When it becomes flush with the housing or is not visible, then the ball joint should be replaced.

Dangers of worn ball joints 

A worn ball joint is not a problem that should be put off—a catastrophic failure of any ball joint will result in your front suspension coming apart and causing a lack of control of your vehicle. Should you speculate worn ball joints, you should have your vehicle checked out by a professional.
