What is the Ball Joint Rear all about?
Rear ball joints are a key part of your vehicle’s suspension system. The ball joints connect the control arm assembly (part of the chassis) to the steering knuckles (part of the wheels). The ball joints serve two purposes: they allow the wheels to steer and they allow the suspension to move freely. The rear ball joint acts nearly identically to the ball joints found in your shoulders and knees; they allow two separate components to operate both independently and together.
Keep in mind:
- It’s a good idea to replace all of the ball joints at once.
- In some cars the control arm blocks the ball joint and will need to be replaced as well.
- After having your ball joints replaced, you should take your vehicle to a mechanic to have the wheels aligned. Mobile mechanics do not have the equipment needed to perform wheel alignments.
How it's done:
- Remove the wheels.
- Remove the control arm(s).
- Remove and replace ball joints;
- Check the entire suspension system for any problems.
Whenever your vehicle is being serviced or having routine maintenance, you should ask for the suspension to be inspected. During a major service, make sure that your ball joints are lubricated, as this will increase their lifespan. If you notice anything wrong with your wheels or suspension, schedule an inspection.
What common symptoms indicate you may need to replace the Ball Joint Rear?
- Steering wheel is shaky.
- Car drifts to one side or the other.
- Rear tires make loud noises and have abnormal wear.
- Suspension makes odd noises.
How important is this service?
The rear ball joints connect the control arm assembly to the steering knuckles, and help the suspension and wheels work smoothly. The rear ball joints help your wheels steer, so as the ball joints are damaged, your car may begin to have steering problems. The rear ball joints also allow the suspension to move, which protects both the suspension and the chassis. Damaged rear ball joints result in a vehicle that is dangerous to drive, and upon driving, can cause further damage to other parts of your car.
