Parts for your 2012 Holden Barina-Suspension bushes

2012 Holden Barina suspension bushes: what they do and when to replace them

Yes, the 2012 Holden Barina (TM series, based on GM’s T300 platform) absolutely uses suspension bushes throughout the front and rear suspension. Technical references confirming this include: GM Service Information (SI) for 2012 Sonic/Barina TM – Front and Rear Suspension Description and Operation, Holden Electronic Parts Catalogue (EPC) for TM Barina – Control Arm, Stabiliser Bar and Rear Axle sections listing multiple bush components, and reputable aftermarket catalogues from suppliers such as SuperPro and Whiteline that offer direct-fit bush kits for the TM Barina. These sources identify front lower control arm bushes, stabiliser (sway) bar bushes and rear torsion/compound crank beam bushes as standard equipment.

On this Barina, bushes are the quiet achievers that isolate vibration, control alignment under load and help keep the tyres tracking straight. Up front, the MacPherson strut setup relies on control arm bushes to keep geometry stable under braking and cornering. At the back, the compound crank rear beam pivots on large bushes that manage compliance and ride comfort. When they harden, crack or delaminate, owners notice extra noise, vague steering and feathered tyres.

There’s no fixed replacement interval, but for Aussie and Kiwi conditions a quick look every service is smart, and a thorough inspection every 20,000–30,000 km is good practice. Typical lifespan ranges from 80,000 to 150,000 km depending on roads, heat and driving style.

• Common signs they’re tired: clunks over speed humps, steering wander, shudder under braking, uneven or rapid tyre wear, and perished rubber visible around the arms or rear beam.
• Inspection tips: with the car safely supported, use a pry bar to check for excess movement, look for splits, oil-soaked rubber and offset arm positions. Any torn bush or excessive play means replacement.
• Replacement advice: many workshops fit complete control arms for speed and to refresh the ball joint at the same time, but individual bushes are also serviceable with the right press tools. Rear beam bushes need a press and correct orientation. Always torque fasteners at ride height to avoid preloading the rubber, and book a wheel alignment straight after.
• Parts choice: Genuine-style rubber keeps factory comfort and NVH. Polyurethane options sharpen response and can last longer, but usually add a touch more road feel and noise.

Done properly, fresh bushes make a Barina feel tight, predictable and easy on its tyres, adding confidence on daily commutes and weekend runs alike.

Popular questions about 2012 Holden Barina suspension bushes

Do all 2012 Barina models use the same suspension bushes?
Most TM Barina variants (hatch and sedan) share the same T300 underpinnings, so core bushes (front lower control arm, sway bar, rear beam) are common. There can be part number differences by engine or build date, so it’s wise to confirm via VIN in the Holden EPC or a trusted parts supplier.

Is it better to replace just the bushes or the whole control arm?
Either approach works. Replacing only the bushes is cost‑effective if you’ve got access to a press and want to retain the original arms. Many workshops prefer complete arm assemblies to save labour and renew the ball joint at the same time. If the arm is bent or the ball joint is worn, the complete arm is usually the better bet.

Will polyurethane bushes make the Barina too harsh?
Poly bushes can firm up steering feel and hold alignment well, which keen drivers like. On the Barina, quality poly in key locations (such as the front rear control arm bush) typically adds a bit more road feel rather than outright harshness. If comfort is the top priority, stick with quality OEM‑style rubber.
