Parts for your 2009 Holden Commodore-Coil springs

2009 Holden Commodore coil springs — what they do and how to look after them

Technical sources including the GM Holden VE Commodore Service Manual (Chassis sections for front MacPherson strut and rear suspension), Holden’s VE engineering overview, and aftermarket manuals (Gregory’s/Haynes for VE 2006–2013) confirm that coil springs are used on the 2009 Holden Commodore. Every model uses front coil-over MacPherson struts, and the sedan and Sportwagon variants use coil springs in the independent rear suspension. The VE Ute keeps a heavy-duty live rear axle with leaf springs for load-carrying, but still runs front coil springs. So yes — coil springs are relevant to this model year.

On a 2009 Commodore, the coil springs carry the vehicle’s weight, set ride height, and work with the shocks/struts to control body movement. Good springs keep tyres in proper contact with the road, which helps braking, cornering, and overall comfort. Over time, springs can sag, crack, or lose tension from metal fatigue, corrosion, or repeated bottoming out on rough roads.

As part of routine servicing, it’s smart to inspect the coil springs at least every 20,000–30,000 km or annually. Look for chipped paint, deep rust pitting, broken ends, or uneven ride height. If one spring is damaged or noticeably lower, replace springs in axle pairs (both fronts or both rears on sedan/Sportwagon) to keep the car sitting level and steering true. When replacing, check the strut mounts, rubber isolators, bump stops, and shocks at the same time — tired shocks will punish new springs and shorten their life.

Common symptoms that point to coil spring issues include:

• Clunks over bumps, a knock when turning, or the car sitting lower on one corner
• Excessive body roll, nose-diving under brakes, or a bouncy, unsettled ride
• Irregular tyre wear that returns quickly after an alignment

DIYers: use a quality spring compressor and follow the VE procedure from a reputable manual. Never heat a spring to compress it, and replace any single-use fasteners as specified. After spring work, get a four-wheel alignment — the VE’s geometry is sensitive, and proper alignment protects tyres and keeps the handling crisp. If you’re considering lowered springs, choose reputable brands matched to your dampers, keep clearances legal, and remember certification/engineering and WOF/roadworthy considerations in NZ and Australia may apply.

FAQs

Do all 2009 Holden Commodores have coil springs?
Yes at the front — every VE Commodore (sedan, Sportwagon, and Ute) uses coil-over MacPherson struts. Sedans and Sportwagons also use rear coil springs in their independent rear suspension. The VE Ute keeps leaf springs at the rear for payload, so only its front end uses coils.

How long do coil springs last, and when should they be replaced?
There’s no strict expiry, but many last well beyond 150,000 km if they’re not abused. Replace them if you spot cracks, a broken coil, heavy rust pitting, or sagging ride height, or if the car handles poorly even with good shocks and a fresh alignment. Always replace in pairs on the same axle.

Can coil springs be changed at home?
Yes, with the right tools and know-how. You’ll need a proper spring compressor, torque specs, and to follow the VE procedure carefully. If you’re not confident, get a workshop to do it — compressed springs store serious energy, and an alignment is needed afterwards.
