What are the symptoms of a bad lower control arm?
Worn or damaged bushings can allow metal on metal contact, tire wear, discomfort, noises, and vibrations. Bushings deteriorate due to heat, age, exposure, heavy loads, salt, oils, and the stress of frequent movement. Another symptom commonly associated with bad or failing control arm components is steering wandering.
What happens if you don’t fix lower control arm?

How often do control arms need to be replaced?
Over time, the control arm assembly can become worn or bent. These assemblies normally wear out between 90,000 and 100,000 miles. They can wear out faster if you go over a large pothole or are involved in a car accident. Various parts of the assembly may wear out as well, such as the bushings or ball joints.
Is it OK to replace only one control arm?
It’s not necessary to replace both, left and right arms if one is bad. Often, however, if one arm is worn out, it’s reasonable to expect that another control arm will likely need replacement soon. In this case, it’s makes more sense to replace control arms on both sides at the same time.

What is the difference between upper and lower control arm?

Should I replace both upper and lower control arms?
It is not necessary to replace both lower or both upper control arms if one is bad, but often they wear out at roughly the same mileage. If one control arm is bad and the other is on its way, it makes sense to replace both arms at once. This way, you only need to do the wheel alignment once.
Do control arms come with bushings?

The joint is attached to a control arm by pressing the joint into the arm or riveting the joint to the arm. The new joint is replaced using bolts and locking nuts. Tie rod end ball joints, on the other hand, are more tolerant of wear.
