We appreciate your inquiry because most drivers are unaware of what a control arm is or how crucial it is. Yes, it’s risky to drive with a damaged control arm.
To begin with, a control arm is a hinged suspension link that is positioned between the chassis and the hub that connects to the suspension and the wheel. The following things may occur if the control arm is malfunctioning:
- Any route will be risky to travel in your car.
- Your steering will be erratic and challenging to manage.
- Even while you are holding the steering wheel straight, your car may pull to one side.
The most vital aspect is safe driving. When your vehicle is ready for the road, focus on checking Jerry’s car insurance rates to make sure you aren’t paying too much.

What is the price of replacing your lower control arms?
A replacement automobile control arm should cost between $500 and $750 on average. Prices may also differ somewhat based on whether a front or rear control arm needs to be replaced, depending on the make and model of your car.
The steering knuckle is connected to the car frame by the control arms, which are an essential component of your vehicle’s suspension and allow your wheels to move up and down when you drive over bumps in the road. Typically, a new automobile control arm runs between $400 and $550.
If you take your car to the shop to have the control arm changed, labor fees will run you another $150 to $200.
Although it’s not necessary to replace a damaged control arm right away, doing so is advised because doing so can prevent more expensive suspension problems in the future.
In order to keep you and other drivers safe on the road, a properly functioning suspension is essential, but so is possessing the appropriate insurance. Finding reasonable rates is now simpler than ever thanks to licensed broker and comparison app Jerry, which spares you from having to deal with a ton of paperwork.
Suppose a control arm breaks while you’re driving.
While you’re driving, if your control arm breaks, you can have difficulties steering, going straight, or a wheel might come off your car. Definitely not ideal!
Your car’s front wheels are attached to it via a control arm. Therefore, if it malfunctions, an accident is likely to occur. Your car would at the very least suffer severe damage.
Your control arm doesn’t, however, suddenly break. There are various indications that it is giving out, including:
- vibrations that are very strong, especially while turning in the direction that the defective arm is facing
- It gets unstable to brake.
- Even after an adjustment, the steering pulls slightly to the left or right.
Make sure you have excellent auto insurance coverage to shield you from potential issues for the utmost peace of mind. Using the Jerry app, getting top-notch coverage without paying too much is simple.
Jerry, a certified broker, enables you to quickly compare rates from more than 50 leading suppliers. Jerry can assist you with purchasing new insurance and even canceling your existing policy when you discover a lower rate.
How durable are lower control arms?
The control arm assembly controls the motion of the wheels by keeping them parallel to the car’s body. They are an essential component of your car’s suspension system since they take the impact of road irregularities and bumps. The control arm assembly connects the vehicle’s suspension to its frame. Ball joints and bushings connect the assembly to the frame and the wheels, respectively. Due to the rarity of cars with this design in the back, this configuration is typically found in the front of vehicles.
The control arm assembly may deteriorate or bend with time. Usually, these assemblies last 90,000 to 100,000 miles. If you drive over a big pothole or are in an accident, they may wear out more quickly. Additionally, the assembly’s bushings and ball joints may become worn out.
Have this assembly inspected each time your suspension is checked out to protect it from wearing down as quickly. In this approach, a qualified expert may appropriately evaluate each component of the control arm assembly. A qualified mechanic can then replace the control arm assembly if one of the parts is defective. Because your car won’t vibrate while you’re driving because of a defective control arm assembly or a bad suspension, the ride will be smoother.
The control arm assembly will eventually malfunction, thus it’s critical that you can identify the signs. As soon as you notice the symptoms, you may get your car checked out and fixed, which is a rather simple procedure.
You should replace your control arm assembly if any of the following apply:
- loud pounding sounds when you cross bumps or potholes
- While you are traveling along the road, the steering wheel or car rattles.
- While you’re driving, the wheels wobble or move.
- There is a decrease in responsiveness of the steering wheel.
- irregular tire wear
When something goes wrong with the control arm assembly, which is a crucial component of your car’s suspension, have it changed as quickly as possible so you can get back on the road safely.
What symptoms point to a malfunctioning control arm?
Here are five warning indications that the control arms on your car need to be replaced.
- 1) A clanging sound When one or more of your vehicle’s control arms fail, one of the first symptoms you’ll experience is a clunking sound.
- #2) The sideward pulling of the vehicle
- Uneven tread wear, third.
- Vibrations While Driving, #4
- #5: Visual harm
What is the turnaround time for a control arm replacement?
The price to replace one lower or upper control arm ranges from $160 to $390. If one arm is damaged, it’s not required to repair both the left and right arms. However, it’s common to assume that if one control arm is worn out, the other one would likely need to be replaced shortly. In this situation, it makes more sense to swap out the control arms on both sides at once.
Wheel alignment is required after replacing one or both control arms (an additional $60–120).
When a lower control arm is changed, do stabilizer bar linkages also need to be replaced? Typically, stabilizer bar links are used to connect the stabilizer bar to the lower control arms.
The nut holding the stabilizer bar link may occasionally become jammed and impossible to remove without breaking the connection. Your mechanic might advise changing the stabilizer bar links as well in this situation. The links are typically inexpensive and don’t require any additional labor when the control arm is replaced in most automobiles.
Can control arm bushings be changed on their own? Control arm bushings that are worn out may occasionally be replaced separately. However, control arm bushings must be installed using a specialized press or tool, which adds to the labor time and cost.
Is it simple to change a control arm at home? The difficulty of changing a control arm is a 7 or 8 on a scale of 1 to 10. One control arm replacement takes the shop between one and one and a half hours.
How do control arms sustain harm?
There are several possible outcomes when a control arm fails. The ball joint typically fails in failures. A steering knuckle detachment and loss of vehicle control can result from total ball joint failure. Additionally, control arm bushings might wear down and stop functioning, resulting in clunking, jerky steering, and loss of control.
What could break a control arm?
Your suspension system’s control arms and bushings are essential parts. They enable your tires to rise and fall in a smooth, regulated motion when they work together. Most rides would be incredibly uncomfortable and uncomfortable without them.
Control Arms
The steering knuckles and wheel hubs are attached to the car’s frame via control arms. They prohibit the wheels from moving forward or backward while allowing them to travel up and down. On both the front and wheel suspensions of most cars, there are one or two upper and lower control arms per wheel. While many front-wheel drive vehicles only employ a lower control arm, the majority of trucks and SUVs use both an upper and a lower control arm.
Bushings
When it comes to reducing vibration, many steering joints and suspensions use bushings. Control arms, shock absorber mounts, stabilizer bars, stabilizer links, engine and transmission mounts, and other steering and suspension parts can all use them. Bushings are particularly crucial since they affect handling and comfort. They soften the ride on bumpy roads by cushioning the suspension system, which reduces noise and vibrations. They can bend and move thanks to their special material, yet they always revert to their initial form and position.
Some Common Problems
Control arms need to be updated since they deteriorate over time like any other auto part. Driving over significant bumps or potholes can cause control arms to bend or break, and bushings can degrade on their own over time. They may eventually shatter due to wear from repeated motions and New England potholes. When driving over bumps, you might hear banging or clanging if your control arm assembly has to be changed.
While worn or damaged bushings can allow metal-on-metal contact, tire wear, uncomfortable rides, noises, and vibrations, they do not serve the same purpose as damaged cartilage, which causes bone-on-bone contact and discomfort. Heat, aging, exposure, large loads, salt, oils, and the strain of continuous movement are the main causes of bushing deterioration.
At V&F
Cheers to Shock-tober! The whole month of October will be devoted to a review of suspension fundamentals, upkeep, and repair. This item has been updated after it was first published in November 2018.
Does it make sense to get new control arms?
The most frequent justification for control arm replacement is to increase wheel travel as part of a suspension raise. A new control arm, however, can provide benefits beyond only increased ride height (lift) and longer wheel travel:
Many high-quality off-road vehicle suspension kits come with a control arm that meets all of these criteria: it has more ride height, more travel, is more durable, and has superior ball joints.
Additionally, wheel alignment is superior to vehicles that raise them using some form of spacer.
