2016 Holden Commodore steering rack — what it does and how to look after it

Technical sources confirm the 2016 Holden Commodore (VF Series II) uses a rack‑and‑pinion steering gear with electric power steering (EPS). This is documented in GM Global Service Information for VF Series II (Steering — Electric Power Steering, Rack and Pinion), reflected in the Holden Electronic Parts Catalogue listings for “Steering Gear (Rack)” for MY16 VIN ranges, and mirrored by the 2016 Chevrolet SS (VF platform) service manual which specifies an EPS rack‑and‑pinion assembly.

On this Commodore, the steering rack is the heart of the steering system. It converts the driver’s steering wheel input into precise movement at the front wheels via the inner and outer tie‑rods, while an electric motor on the rack provides assistance. Compared with older hydraulic setups, the EPS rack delivers lighter parking effort, sharper road feel, and better fuel efficiency because there’s no belt‑driven pump dragging on the engine.

There’s no power‑steering fluid to top up on the VF II’s EPS rack, so routine care is all about inspection and alignment. During servicing, a good workshop will check the rack boots for splits, feel for free play in the inner and outer tie‑rods, confirm the rack is tight on its mounts, and make sure wheel alignment is spot on to avoid uneven tyre wear and steering pull. If a battery has been disconnected or alignment work is done, they may carry out EPS and steering angle calibrations using GDS2 to keep the assistance and centring behaviour sweet.

• Listen/feel for knocks over bumps, heavy or notchy steering, or play at centre — all are clues the rack or tie‑rods need attention.
• Watch for an EPS warning lamp or fault codes, software updates or calibrations can resolve certain complaints.

When replacement is on the cards, it pays to choose a genuine or high‑quality remanufactured rack. The EPS unit must be programmed to the vehicle and calibrated (torque‑sensor and steering angle), which requires the right scan tool and know‑how. Expect a wheel alignment afterwards, and on some jobs the front subframe is loosened or lowered, so fresh torque‑to‑yield hardware may be required by the book. Smart techs also check the intermediate shaft, front control arm bushes, and tyres at the same time so the new rack isn’t masking other issues. Done properly, a fresh rack brings the VF back to that confident, direct steering feel Commodore owners rate so highly.

Popular questions about 2016 Holden Commodore steering racks

Does a 2016 Holden Commodore have a steering rack?
Yes. The VF Series II uses an electric power‑assisted rack‑and‑pinion steering gear. There’s no hydraulic pump or fluid service, but the rack, tie‑rods and alignment still need periodic checks.

What are common signs the rack needs work?
Knocking over bumps, free play at the wheel, heavy or self‑centering issues, uneven tyre wear, or an EPS warning light. A proper inspection will confirm whether it’s the rack, tie‑rods, alignment, or a worn suspension bush.

Does the EPS rack need programming if replaced?
It does. A replacement rack requires coding to the car and calibrations (torque sensor and steering angle) with a suitable scan tool, followed by a four‑wheel alignment for best results.
