Control Arms

Control arms locate the wheel hub while allowing the suspension to move through its travel, using bushes at the chassis and a ball joint at the hub.

What it does

The arm holds wheel geometry under braking and cornering. Its bushes allow a controlled pivot while the ball joint lets the hub steer and move vertically.

Signs a control arm is failing

A clunk over bumps or when braking
Steering that wanders or pulls
Uneven tyre wear
Visible damage to the arm, bushes or ball joint boot

When to replace them

Not a scheduled item. Replace when the bushes or ball joint have play, the arm is bent, or corrosion compromises its strength.

What to confirm before ordering

Have these ready and the counter can usually confirm the part in under a minute.

Front or rear, and left or right side
Whether bushes and ball joint are included
The vehicle engine and drivetrain, where the arm differs by specification
Wheel alignment should be booked after replacement

Control Arms by vehicle

Pick your vehicle for the years and engines covered, and what is specific to that application.

Control Arms questions

Do control arms need to be replaced in pairs?

Not always, but inspect the matching side. The bushes and ball joints have experienced the same mileage, so replacing both can avoid a second alignment and repair soon after.

Is wheel alignment needed after replacing a control arm?

Yes. A control arm locates the wheel, so alignment should be checked and adjusted once the new arm is fitted.
