What Is a Steering Rack (Rack and Pinion)?
The steering rack turns your wheel input into wheel movement. A Cranbourne West specialist explains.
What it is & what it does
The steering rack converts the rotation of the steering wheel into the side-to-side movement that steers the front wheels — via a pinion gear on a toothed rack. Hydraulic racks are assisted by fluid pressure; modern electric racks have the assist motor built in.
The tie rods connect its ends to the wheels.
Signs of trouble & how we help
A worn rack causes play or a notchy feel, knocking over bumps, leaks (hydraulic), or assist faults (electric — often a warning light and heavy patches). Worn inner tie-rod ends inside the rack boots are a common wear point that feels like rack play.
We isolate rack wear from tie rods and mounts before quoting — racks are the expensive answer, and often it isn’t the rack.
