Nissan Altima Control Arms and Parts
Control arms and parts for Nissan Altima provide a smoother ride and connect the wheels to the steering mechanism. As a result, a broken or damaged control arm makes driving more difficult. It's important to learn more about control arms and parts so that you can find the replacements you need to make repairs.What is a control arm?
Control arms are the part of a vehicle’s suspension system that controls the movement of the wheels. They stabilize the wheel by attaching it to the frame. This keeps the wheels from wobbling and jerking when you hit bumps and dips in the road. They also attach the wheels to the steering mechanism so that they will turn as you steer. Each wheel has an upper and a lower control arm, which makes a total of eight control arms per vehicle.
Control arms are triangular-shaped parts that attach to a knuckle or ball joint on one end and to a bushing on the other end that is mounted to the car’s frame. The bushing gives the control arm a range of motion, and the ball joint connects both control arms to the steering.What types of control arms are there?
There are two main types of control arms used in automobiles depending on the type of suspension system they have.
- Double wishbone: This is the type found in the Nissan Altima. This type uses a pair of control arms, upper and lower, to fix the wheel in place and steer it.
- McPherson single arm: This type has a vertical strut and spring that attaches the wheel to the frame and isolates the car from the bumps and dips in the road. The wheels also have lower control arms that stabilize and steer them.
- Excessive play in the wheel: If you can wriggle the wheel back and forth easily when it's jacked up off the road, it may be caused by a control arm that has come loose.
- Rough ride: If you start to feel the hard bumps on the road as sudden impacts, your suspension is failing. Control arms are one part of the suspension that could cause this.
- Hard steering: If it becomes more difficult to steer your Altima or there’s excessive play in the wheel’s direction, it could be a damaged control arm at fault.
Control arm repairs involve ball joints, bushings, and fasteners like bolts and cotter pins. Parts and hardware that typically need to be replaced during a repair are included in most control arm kits.
