The rear lower control arm is an important part of your car’s suspension. Your suspension, in turn, is a pretty important part of your car. Hopefully you knew that. If not, just take my word for it. The control arms serve to connect the steering system to the frame of the car. This limits the amount of force placed on the car, which reduces the unnecessary and unwanted movement. Many cars have at least four control arms: One for each wheel. Some cars have upper and lower control arms. Made from a strong and highly-durable metal, the rear control arms, which are sometimes referred to as trailing arms, connect to the frame at one end. At the other end, each control arm usually connects to either a knuckle or the axle housing. When the vehicle travels over a bump, the control arm pivots on bushings, allowing your car’s wheels to move up and down. The control arms, which are made of steel or aluminum, are very strong, and limit the movement of these steering components. Left to their own devices, the steering knuckles or axle housing would move around quite a bit, and that would get transmitted into the cabin of your car. And you would be unhappy. And annoyed. But that doesn’t happen, thanks to the control arms. Some cars have both an upper and a lower control arm in the rear, which is pertinent, since you’re reading an article on rear lower control arms. Control arms are very durable. They have bushings and ball joints attached to them, which will need to be replaced every now and again, but the rear lower control arm itself is unlikely to break, unless you get in a car crash.
Here’s some news for you: Vibrating cars aren’t such a hot thing. So, if your car vibrates, don’t just stare at it in wonder. Get that thing taken care of. If your rear lower control arms call out sick, then the vibrations of the steering system will start to make their way back into your car, into the cabin. And suddenly that wheel will shake like you do after your third cup of coffee. At first the vibrating and shaking might not be a big deal, but it will get worse, and it will be a pain in the butt. Or hands.
Welcome to Cars 101. Our first lesson? Weird noises are not good. Pay attention to weird noises. Address weird noises before they get worse. Lots of different things in your car can make lots of different weird noises. If your rear lower control arm is failing, it will likely make a knocking noise. It will be annoying, which is good, because otherwise you might not actually do anything about it. I’m just being honest here. We all know it’s the truth. That annoying knocking noise will just get worse as the control arm breaks more and more, so if you’re just crossing your fingers and hoping for the best, good luck.
Pulling is a weird sensation. It’s when your car starts…well, pulling to one side or the other while you’re driving. It’s an odd sensation. Your car can pull to the left or the right for a few reasons. Most common among them is uneven wear and tear on your tires, or a car in need of an alignment. But your car can also begin to pull if the rear lower control arm is busted. Being able to steer properly is kind of important when it comes to driving. So, take it seriously when your car doesn’t feel like going in a straight line.
A malfunctioning front rear lower control arm can cause your wheels to be improperly aligned, which will make your tires wear unevenly. It’s a good idea to visually inspect your tires with some regularity, so you can spot issues before they get too severe.
The most common way for a rear lower control arm to break is through an accident. If your car has been in an accident and is exhibiting these symptoms, then this replacement is extremely urgent.
If it’s just beginning to die on its own, and you’re only noticing small symptoms, then it’s safe to drive for short distances. But don’t push it,. This is your steering and suspension we’re talking about. Just get it taken care of.
