What to know about the Control Arm Assembly:
A control arm set (lower and upper) joins the front suspension of the car to the frame of the car. It is joined to the wheels through ball joints, and to the frame of the car through bushings. It is usually found on the front side of the car. (Few cars have control arms in the back.) If the control arm is bent (can happen when you are in an accident or go over a large pothole), or the bushings wear out, you may have to change the control arm assembly. It is a good idea to change the bushings and the ball joints while doing this service.
Facts to Note:
The vehicle may require to be taken to a shop for wheel alignment after this service. Mobile mechanics do not have the machinery to align wheels.

How to Fix:
Confirm that the control arm or bushings are abnormal.
Take away the control arm.
Fix the new control arm assembly

Test drive the vehicle.
Any time your suspension is checked, you should have your control arm assembly checked too. A mechanic can survey an entire suspension system and assess the health of each part. However, if you observe that your suspension is abnormal, either through strong vibrations, loud noises, or lose steering, then you should schedule an inspection.
Common symptoms indicating you may need to change the Control Arm Assembly:
Banging noises when driving over the bumps or turning the car.
Wheel assembly moves or shakes.
Steering wheel feels loose.
Steering wheel or car vibrates when driving.
The tires are worn.
Importance of this service:
The control arm assembly joins the vehicle’s suspension to the wheels via ball joints, and to the frame of the car via bushings. Your vehicle has four control arms – one for each wheel – and they help synchronize all four wheels, while maintaining the vehicle and the suspension steady. When the control arm assembly is spoilt, the wheels no longer work in harmony with each other or with the suspension. This results in a very uncomfortable ride and can inflict serious damage to the suspension system.
