Parts for your 2017 Holden Commodore-Steering rack

2017 Holden Commodore Steering Rack

Technical sources confirm a steering rack is absolutely relevant and fitted to the 2017 Holden Commodore (VF Series II). GM/Holden factory service information for VF Series II specifies an electric power-assisted rack-and-pinion steering gear, and the VF Owner’s Manual describes Electric Power Steering (EPS) rather than a hydraulic system. Workshop diagrams for the model show a rack-and-pinion assembly with an integrated assist motor and control module on the rack.

On a 2017 Holden Commodore, the steering rack’s job is to turn the driver’s input at the wheel into precise side-to-side movement at the front wheels. Being an EPS setup, the assist motor is mounted on the rack itself, so there’s no power-steering pump, belts, or fluid to worry about. That makes it quieter, more efficient, and easier to tune for good road feel, whether it’s a city runabout or a long haul down the motorway.

As part of routine servicing, the rack isn’t a scheduled replacement item, but it does deserve a once-over. A good technician will check the rack boots for splits, inspect inner and outer tie rod ends for play, and make sure the mounting points are tight. Because it’s electric, they’ll also scan for EPS fault codes, confirm the steering angle sensor reads true, and note any notchy feel or kickback on a road test. There’s no fluid to flush on this model, but tyre pressures, wheel alignment, and suspension bushing condition make a massive difference to steering feel and tyre wear.

If the rack needs replacing (from impact damage, worn internal gears, or motor/torque sensor faults), expect a proper process: battery support to protect electronics, locking the steering in the straight-ahead position, disconnecting the column safely to avoid clock spring damage, and removing the rack from the front subframe. After fitting, the car will need a steering angle sensor reset and EPS initialisation with a scan tool, plus a full four-wheel alignment. It’s smart to replace any single-use fasteners as specified by GM and to recheck column universal joints and tie rod torque. Signs it’s time to act include clunks over bumps, free play at centre, wandering on the highway, uneven tyre wear, EPS warning messages, or a sudden change in steering weight. Done right, a quality rack and alignment will have the Commodore tracking straight and feeling tight for many kilometres.

Does the 2017 Commodore use electric or hydraulic power steering?

It runs electric power-assisted steering (EPS) on a rack-and-pinion. There’s no power-steering fluid reservoir or pump, which cuts maintenance and improves efficiency and tuning of steering feel.

What are common signs the steering rack needs attention?

Free play at the wheel, clunks over bumps, notchy or heavy steering, uneven tyre wear, pulling to one side, or an EPS warning. Torn rack boots or looseness in tie rod ends are also red flags.

After replacing the rack, is programming needed?

Yes—an EPS initialisation and steering angle sensor reset with a suitable scan tool are required. A four-wheel alignment is also essential to protect tyres and restore on-centre feel.
