Factors Affecting Price of Control Arm Replacement 

As earlier mentioned, factors like geographical location, labor, model, and make of the car all affect the price of replacing the control arm.


Many cars use the MacPherson suspension (possessing little modifications), makings it easy to interchange control arms between cars. Therefore, if you are buying a rear or front control arm, it will not matter. First, because they are interchangeable, and secondly, it is not expensive because of the mass production.

More expenses are made for cars that use custom control arms. However, we have some advantages, such as smoother suspension. Unfortunately, this makes the parts more expensive.

Hence, the control arms of a Toyota can start at $15.49, whereas Chevy is an estimated $100 and BMW over $250. That is why the car’s model and make are considered.


One can decide to purchase upgraded vehicle control arms.

It has been realized that suspension upgrades are amongst the best ways to enhance your car’s steering and driving performance.

Although, better or upgraded control arms are more expensive. A particular control arm that suits a car can cost between $20 to $700.

Labor Costs

Usually, the garage plus mechanic fee is paid hourly to replace the control arm.

The installation will cost an estimated $100 other times; it will be slightly more.

Most times, labor is more expensive than replacing the control arms. So be ready to pay between $100 to $250 for labor fees.

Remember, mechanics, charge differently in various regions. Therefore, the region you are in will also depend.

Consider the fees charged by your local mechanic when working out the possible expenses.

What Is The Control Arm?

The part of your car links the suspension to a car’s frame. A control arm also links your steering knuckle responsible for holding the car’s front wheel to one of the car’s frames or body. It has a high value because it keeps the wheels of a car steadily fixed to the entire car.

As a vehicle travels on the road, the suspension moves up and down; this is why it is important for your control arm to permit the movement to happen. This can be attained by using the control arm bushings that are flexible and built of rubber. Using ball joints, control arms are linked to your steering knuckles allowing your wheels to rotate.

In most vehicles, the control arm is normally either shaped as a letter L or A, then two(2) ends are linked to a chassis. However, others will possess a dissimilar shape of one shaft with the ball joint at a particular end; then, the rubber bushing will be at the other.

A suspension spring will be inserted in the middle for cars that own two (2) control arms for each wheel.

Signs of a Bad Control Arm

You can easily notice when the control arm becomes faulty. Most times, it starts making noise, the car vibrates excessively, and your steering starts having an issue.

If your car is clunking, popping, or squealing during the first startup or steer of your car, the control arm is possibly faulty.

Especially when you try to speed, slow down, etc., and it makes a popping noise.

Also, you can shake the tire and listen to the clunking noise.

The noises might be from numerous issues like worn bushings, ball joints, etc. Take your car to a mechanic if you cannot discover the reason for the noise.

2. Irregular Tire Wear

When you notice uneven wear in your tires, it might mean a suspension issue, and you need to hand your car in for an alignment.

Uneven tears can result from a faulty control arm, especially if other symptoms appear.

3. Wobbling Steering

It is considered the most dangerous and common sign of a faulty control arm. When your car goes over bumps, it either veers to its right or left.

If this is added with excessive vibration, driving becomes very hard.

4. Vibration Issues

Excessive vibration while speeding up, driving, or slowing down a car can be a faulty control arm.

As explained in “uneven tear,” the vibration might relate to the suspension. You will then have to physically examine your car to know if it has a faulty control arm.

What is the Process for Replacement?

You will need a sound jack or lift; afterward you have to service the car and get its suspension balanced.

Tools that you will need:

  • Rubber Mallet or Tie Rod Remover Tool

  5. Bring out the tie rod using a tie rod puller. You can also use a rubber mallet to hit(knock) under the nut and loosen the tie rod. Then remove it by pulling.
  6. The ball joint is then loosened by placing a wrench on it. Then knock off the ball joint by using a fork and hammer.
  7. Unbolt the front of your control arm
  8. Unbolt the back of your control arm
  9. Keep wriggling the assembly of your control arm till it falls out.
  10. Then, place your new control arm into space. Change all the bolts; your ball joint is included.
  11. Change the wheel and tie the rod arm.

Examine your wheel to know if it makes noises or clunks. In the parking lot, take a test drive to examine the suspension.
