Audi Control Arm
Just after mastering the four-stroke IC engine, globally all the auto-manufacturers turned to pay their due attention and sincere concern towards the Audi's suspension system. Audi's suspension system is meant to provide a strong road holding and braking characteristics for safe driving direction; along with comfortability of Audi's occupant simply by isolating them from bumps, vibrations and noises. The term suspension is given to the system of springs, shock absorbers and linkages. The Audi suspension system is divided into three major types such as dependent suspension, independent suspension and semi-dependent suspension. These are further sub-grouped as front suspension and rear suspension. Outstanding and satisfactory performance of Audi's suspension is only possible because of the different sub-components capable of performing an intended task. Various suspension parts come together in order to provide a superb handling and exceptional steering ability to your Audi. One such reliable and durable sub-component of a suspension system is, Audi's Control Arm.
Basically, a control arm is a suspension component which connects the wheel flange to the chassis of your Audi. The tapered end of Audi control arm is made up of ball joints to attach the wheel flange where as the wide end of the Audi control arm is made up of pivots or rubber bushings and is attached to the chassis or frame of your Audi. Both of the components work together, to come up with the coziest ride for you. Audi control arm is placed in between the frame and the rear axle to connect different suspension features to the chassis of your Audi. It is designed in a way to carry away the flexes of control of your Audi, simply by carting brake and driving torque. Due to its bar shaped triangular sub-frame like an alphabet A, it is also known as an A-arm or a wishbone. The Audi control arm is mounted with the front suspension besides the McPherson struts.
Symptoms of a faulty Audi Control Arm
- Worn-out rubber bushings in one or both sides of your Audi may vibrate while going on a bumpy ride or driving at a high speed. The bushings are meant to cushion the Audi control arm at work, if they are worn-out they start giving you steering problems accompanied by abnormal abrasion of tire of your innovative Audi.
- The axial or radial play of the wheels of your Audi may start vibrating due to the loose ball-joint. Also, if an unusual clunking or popping noise is audible to you while a sharp turning or going over a bump, is probably due to its prolong use or improper and insufficient lubrication of ball-joint.
How to check a faulty Audi Control Arm?
- You may check for worn bushings by pushing the control arm in a way which completely goes against its normal motion and if it continues to move with respect to its shaft, it simply signifies that the bushings are worn and seeks an immediate replacement.
- You may examine the worn ball joint by checking the wear indicator or measuring the amount of play in the joint.
