The wheel is held on to a hub connected to the steering knuckle. The knuckle allows the wheel to steer left and right and is attached to the control arm(s). The control arm allows allow the wheel to travel up and down over bumps and helps to position the wheel in the proper alignment. How does the control arm work?The control arm is connected on one end to the steering knuckle (to which the wheel is attached by way of the hub and bearing assembly) by a ball and socket called a ball joint. It is attached at the other end to the vehicle frame or body. When a car goes over a bump, the control arm pivots up and down with the wheel and allows the vehicle body to remain stable. On the frame/body side, the control arm has a bushing (or pair of bushings) that allows it to pivot. What are the symptoms related to a bad control arm?The actual control arm may last the lifetime of the vehicle. The control arm bushings, on the other hand, often wear out as a vehicle approaches 100k miles. A control arm is prone to damage if the vehicle is in a crash or encounters a large pothole. If the bushings are worn out, the suspension will make a squeaking sound when going over bumps. If they are severely worn, a knocking sound may be heard as the control arm makes metal-to-metal contact with the bushing bracket. If the control arm is damaged or bent, tire wear may be uneven and the vehicle may pull to one side or wander. Can I drive with a control arm problem?If the control arm on a vehicle is damaged in a crash or impact with a pothole or parking block, the suspension will be out of alignment and cause uneven tire wear and poor vehicle handling. The control arm should be replaced as soon as possible. If the control arm bushings are worn, the result will be an annoying squeak when the car goes over bumps. In this case, the car can be driven. But if the bushings wear out considerably, metal-on-metal contact may happen between the control arm and the bushing bracket. This can cause further suspension damage and the control arm or bushing should be replaced. How often do control arms need to be replaced?While there is no prescribed frequency for replacement of a control arm, the bushings may wear out and need to be replaced as a vehicle approaches 100k miles. Driving aggressively or over rough roads can decrease the lifespan of the control arm bushings. How are control arm issues diagnosed?A technician may diagnose a worn lower control arm during a test drive of the vehicle. The condition may also present itself during a bounce test, where the technician will press down firmly on one corner of the vehicle to bounce the suspension and pivot the control arms. A damaged or bent control arm may show up during a four wheel suspension alignment since the control arm determines the position and angle of the wheel. How is a control arm replaced?A technician will replace a lower control arm by first lifting and supporting the vehicle in the air on a hoist and removing the wheel and tire. A lower control arm must be disconnected from the lower ball joint (attached to the steering knuckle) and from the vehicle frame or body. An upper control arm is disconnected from the strut tower on the body and from the top of the steering knuckle. Some control arms come with bushings permanently installed in them, while others require the bushings to be installed. It is common to replace related components - ball joints, tie rod ends, sway bar links - at the same time that a control arm is replaced. RepairPal Recommendations for control arm issuesRepairPal recommends inspecting (and replacing if necessary) the ball joint at the same time that the control arm is being replaced. Since the control arm determines the position of the wheel and tire, a four wheel alignment is also recommended after a control arm is replaced. What to look out for when dealing with control arm issuesIf a control arm is damaged, the suspension alignment will be compromised. In addition, rubber bushings are adversely affected by heat and by petroleum products (grease and oil). It is important to periodically inspect the control arm bushings to make sure they are free from grease or oil. Also, in order to replace a control arm, the vehicle needs to be safely raised and supported on a hoist or a jack and jack stands. Can I replace the control arm myself?Replacement of a control arm is generally an intermediate DIY repair. On some vehicles, the control arms come with the bushings already installed. On other vehicles, the bushings need to be pressed into their housings on the control arm before installation into the vehicle. In this case, the repair will be more difficult. Also, this repair requires that the vehicle be safely lifted and supported with a jack and jack stands. Failure to do so in a safe manner can result in serious injury or death. How much does labor cost to replace a lower control arm?A new car control arm usually costs between $400 and $550. Labor costs—if you take your vehicle to the mechanic to have the control arm replaced—will add on another $150 to $200.
Can you replace just one lower control arm?Ball joints typically cannot be replaced separately, so the entire control arm needs to be replaced. The ball joints are critical to vehicle alignment, so these control arms should also be replaced in pairs. Inspect the ball joint boot and look for signs of dry rotting or cracks, as well as leaking grease.
Can I drive with a damaged lower control arm?How long can I drive with the damaged control arm? With the damaged or worn-out control arm, you can drive your vehicle for a week or less but it should be repaired as soon as you detect the problem through the methods given above before the suspension gets broken.
Is it worth replacing control arms?The most common reason to replace a control arm is to improve wheel travel as part of a suspension lift. However, a new control arm can offer more than just increased ride height (lift) and additional wheel travel: Increased durability in the arm itself. A wider range of uniball/ball joint options.
