Parts for your 2015 Holden Captiva 5-Strut mounts

2015 Holden Captiva 5 strut mounts — purpose, fitment and servicing tips

Technical sources confirm the 2015 Holden Captiva 5 is fitted with front strut mounts. GM Service Information for the Captiva CG Series II specifies a front MacPherson strut assembly with an upper insulator/bearing (the strut mount). The Opel Antara/Chevrolet Captiva platform workshop manuals show the same layout, and reputable aftermarket catalogues (e.g., Monroe and KYB) list dedicated front strut-mount kits for Captiva 5 models. That means strut mounts are relevant on the front axle, the rear uses separate springs and shock absorbers, so rear “strut mounts” aren’t applicable.

On this model, the strut mount sits at the top of the front strut. It cushions road shock and vibration so less harshness makes its way into the cabin, and the built‑in bearing lets the strut rotate smoothly when steering. In short, it keeps the front end quiet, tight and predictable while protecting the body from bumps.

There’s no fixed replacement interval in the factory schedule, but mounts are wear items. Many Captiva 5 owners see them last anywhere from about 80,000 to 150,000 kilometres, depending on road conditions and loads. Best practice is to replace the strut mounts in pairs whenever front struts are replaced, or sooner if symptoms show up.

• Common signs of worn strut mounts on a Captiva 5:
  • Clunks, knocks or creaks over speed bumps and potholes
  • Notchy, heavy or slow‑to‑centre steering (bearing wear)
  • Excess vibration or a “thud” felt through the dash or steering wheel
  • Uneven front tyre wear or vague turn‑in

During servicing, a quick visual and hands‑on check goes a long way. Look for perished or cracked rubber, a collapsed mount (reduced ride height at one corner), separated bonded metal, or rust and play around the centre bearing. Any of these call for replacement. When fitting new mounts, go with quality components that include the bearing, and follow GM torque specs. It’s smart to add new bump stops and dust boots at the same time, then finish with a full wheel alignment to reset camber and toe.

Keeping the Captiva 5’s front strut mounts healthy helps maintain a quiet ride, sharper steering feel and more consistent tyre wear — exactly what’s wanted on Aussie and Kiwi roads.

FAQs

Does a 2015 Captiva 5 have strut mounts front and rear?
Yes at the front, no at the rear. The front uses MacPherson struts with top mounts and bearings. The rear suspension is a separate spring and shock setup, so there’s no rear strut mount to replace.

How long do strut mounts typically last on a Captiva 5?
Often 80,000–150,000 km, but it varies with road quality and driving loads. Listen for knocks and watch for steering notchiness — those are the usual early warnings.

Should strut mounts be replaced with the struts?
Highly recommended. New struts with tired mounts can still knock and feel vague. Replacing mounts and bearings in pairs, then aligning the front end, gives the best result.
