What Is a Control Arm (Wishbone)?
Control arms locate your wheels and let the suspension move. A Cranbourne West specialist explains.
What it is & what it does
A control arm (wishbone) connects the wheel hub to the car’s body, locating the wheel while letting the suspension move up and down. It pivots on bushes at the body end and a ball joint at the wheel end. Many modern cars have several per corner (multi-link).
Healthy arms and bushes give precise steering and a quiet ride.
Signs of trouble & how we help
Worn control-arm bushes or ball joints cause clunks over bumps, vague steering, and uneven tyre wear. An alignment is needed after replacement.
We inspect the arms, bushes and ball joints on the hoist and replace what’s worn, then align the car.
