The 2019 Hyundai Tucson is a stylish and reliable compact SUV that offers a comfortable ride and advanced features. Among its critical suspension components, the control arm plays a crucial role in maintaining stability and ensuring smooth handling. In this blog, we will delve into the importance of the control arm, its function, common issues, maintenance tips, and the process for replacing it in the 2019 Hyundai Tucson.
What is a Control Arm?
Function and Purpose
The control arm, also known as an A-arm or wishbone, is a key component of the vehicle’s suspension system. It connects the wheel hub and steering knuckle to the vehicle’s frame, allowing for controlled movement and maintaining proper alignment of the wheels. The control arm ensures that the wheels remain in constant contact with the road, providing a smooth and stable ride.
How Does a Control Arm Work?
The control arm pivots on two points, attaching to the frame at one end and the wheel hub at the other. It moves up and down with the suspension, absorbing road shocks and maintaining the alignment of the wheels. The control arm is equipped with bushings and ball joints that provide flexibility and allow for the necessary movement while keeping the wheels aligned.
Importance of the Control Arm in the 2019 Hyundai Tucson
Stability and Handling
The control arm is vital for maintaining vehicle stability and precise handling. It ensures that the wheels stay aligned with the vehicle’s frame, providing consistent contact with the road and enabling responsive steering.
Ride Comfort
By absorbing road shocks and vibrations, the control arm contributes to a smooth and comfortable ride. Properly functioning control arms help reduce road noise and vibrations felt inside the cabin.
Tire Wear
Control arms help maintain proper wheel alignment, which is crucial for even tire wear. Misaligned wheels caused by faulty control arms can lead to uneven tire wear, reducing tire life and affecting vehicle safety.
Common Issues with Control Arms
Worn Bushings
The control arm bushings, made of rubber or polyurethane, can wear out over time due to constant movement and exposure to road elements. Worn bushings can cause clunking noises, vibrations, and reduced handling performance.
Damaged Ball Joints
Ball joints connect the control arm to the wheel hub, allowing for pivoting movement. Over time, ball joints can wear out or become damaged, leading to loose or unstable steering and excessive tire wear.
Bent or Cracked Control Arm
Impact from potholes, curbs, or accidents can bend or crack the control arm, compromising its structural integrity. A damaged control arm can lead to misalignment, poor handling, and increased tire wear.
Signs of a Failing Control Arm
Clunking or Popping Noises
Unusual noises, such as clunking or popping sounds when driving over bumps or turning, can indicate worn or damaged control arm bushings or ball joints.
Vibrations in the Steering Wheel
Excessive vibrations in the steering wheel, particularly at higher speeds, can be a sign of worn control arm components. These vibrations often result from loose or damaged bushings and ball joints.
Uneven Tire Wear
Uneven or rapid tire wear, especially on the inner or outer edges, can indicate misaligned wheels caused by a failing control arm. Regularly inspecting tire wear patterns can help identify issues early.
Poor Handling and Steering
If the vehicle feels unstable, drifts to one side, or has loose steering, it could be due to a failing control arm. These symptoms affect the overall safety and handling of the vehicle.
Maintaining Your 2019 Hyundai Tucson Control Arms
Regular Inspections
Regular inspections of the control arms and suspension components are crucial for early detection of issues. Include control arm checks during routine maintenance, such as oil changes or tire rotations.
Keeping Components Clean
Keeping the suspension components clean helps prevent corrosion and wear. Regularly washing the undercarriage, especially during winter months, can help remove road salt and other contaminants.
Addressing Symptoms Promptly
If you notice any signs of failing control arms, such as unusual noises, vibrations, or uneven tire wear, address them promptly. Ignoring these symptoms can lead to more severe issues and costly repairs.
Replacing the Control Arm in the 2019 Hyundai Tucson
Tools and Materials Needed
- New control arm (OEM recommended)
- Jack and jack stands
- Lug wrench
- Socket set and wrenches
- Ball joint separator or pickle fork
- Torque wrench

Step-by-Step Replacement Guide
- Preparation:
- Park your Tucson on a flat surface and engage the parking brake. Loosen the lug nuts on the front wheels but do not remove them yet.
- Raise the front of the vehicle using a jack and secure it with jack stands. Remove the front wheels using the lug wrench.
- Locate the Control Arm:
- Identify the control arm connected to the frame and the wheel hub. It is usually an A-shaped or wishbone-shaped component.
- Remove the Control Arm:
- Use pliers to remove any cotter pins and loosen the nuts securing the ball joint to the steering knuckle.
- Use a ball joint separator or pickle fork to separate the ball joint from the steering knuckle.
- Remove the bolts securing the control arm to the frame and carefully detach the control arm from the vehicle.
- Install the New Control Arm:
- Position the new control arm in place and secure it with bolts. Tighten the bolts to the manufacturer’s recommended torque specification.
- Attach the ball joint to the steering knuckle and secure it with the nut. Insert a new cotter pin to secure the nut.
- Reinstall the Wheels:
- Reinstall the front wheels and tighten the lug nuts by hand.
- Lower the vehicle from the jack stands using the jack.
- Tighten the lug nuts to the manufacturer’s recommended torque specification.
- Final Checks:
- Start the engine and test drive the vehicle to ensure smooth operation.
- Check the alignment and have it adjusted if necessary to ensure proper handling and tire wear.
