Control Arm

What are car control arms and what is the average cost of replacing them?

Control arms are part of the suspension which locates and controls the movement of the hub and strut. There are usually a couple control arms on each corner of the vehicle. They also have bushings and ball joints which is usually why they need replacement ovetrtime, since those are wear items. The cost to replace varies depending on the vehicle. Control arms cost different amounts depending on the vehicle, as well as the labor to install. Some are easy to install and take little time, while others can take several hours.

Do I need to replace the control arm if the bushings are worn? What is the safety risk?

Likely the replacement control arm comes with new bushings, although I'm not an expert in that particular car.  Most come as a unified assembly these days, and for a car as widely produced as the Accord, you could probably replace the entire unit for cheaper than just replacing just the bushings, but I'm not an expert in that particular car. Its always worth it to replace bushings on control arms.  I wouldn't mess with anything that has to do with integrity of the front suspension, unless you live somewhere where the roads are perfect and pristine, you never have to make evasive maneuvers, and you don't ever turn.   It also can substantially effect the front end alignment, depending on how worn it actually is, which effects how straight the car goes on the highway, and how well it responds to steering input.Front ends, while really sturdy, need to be intact to be operate as designed.   I realize you may not want to spend any money on it and want it to last another year, but its an  unfortunate false economy to not replace a control arm bushing.

What is the function of lower control arms?

Those are the bottom most mounts for your front wheels spindles. They set a lot of your alignment parameters and certain bearing surfaces becoming loose can cause steering and tire wear issues.They can also be bent from collision and abuse.
