Control arms, also called "A arms," are important parts of the front suspension in an Acura vehicle. One can have two to four of them. What they do is connect wheel assemblies or steering knuckles to car frames or bodies. Their outer ends attach to ball joints, which are either permanently fastened, pressed on, or bolted in place. They also have rubber bushings that allow them to swing vertically. This helps smooth out the ride as the vehicle goes over bumps and potholes.
When control arm parts work together the way they should, wheels and tires stay on the road the way they should. When they don't, however -- say, when they get damaged or wear out because of use and age -- they can bend (if they don't otherwise break), and that's sure to make any car or SUV unsafe to drive.
Luckily, when control arms go bad, there are clear signs. They range from brake drift across uneven terrain and clunking or popping sounds to the loss of some control while driving. These symptoms usually indicate a worn ball joint or torn bushing. Both can result in wheels detaching from the suspension completely. To avoid that catastrophe, be sure you hoist your Acura up on a lift and do a full inspection. Take care of this at least once a year.
If it turns out you need to replace one or more, be sure you buy genuine Acura control arms. Those made by your brand are guaranteed compatible with what you drive, after all.
