What are Front Control Arm Bushings?
Let’s start with what the control arms are, and work our way backwards, shall we?
The control arms serve to connect the steering system to the frame of the car. They reduce the amount of force that is dealt to the car, which in turn limits unnecessary movement.
Many cars have at least four control arms: One for each wheel. Front control arms usually connect to the frame at one end and the steering knuckle at the other. When the vehicle travels over a bump, the control arm pivots on bushings, allowing your car’s wheels to move up and down.
Left on their own, the steering knuckles would move around quite a bit, and that would get transmitted to your car, your steering wheel, and your hands. That’s not what you want. And it’s not what you get, thanks to the front control arms.
So, now we move on to the front control arm bushings. Most control arms have two bushings, which are located where the control arm attaches to the frame of your car. The bushings, which are made of metal but covered in either rubber or polyurethane, keep the metal control arms from excess contact with the metal frame of the car. This limits noise, and vibrations.
While the front control arm bushings are designed to withstand lots of wear and tear, they can give out over time. When that happens they’ll need to be replaced, and, depending on your car, the control arms may need to be replaced as well.
