2008 Mazda CX-9 strut mounts — what they do and when to replace them

Strut mounts are absolutely relevant on the 2008 Mazda CX-9. The front suspension on this model is a MacPherson strut design, which by definition uses a top strut mount to attach the strut assembly to the body and allow the strut to pivot for steering. This is set out in the Mazda CX-9 (2007–2012) Workshop Manual under Front Suspension — MacPherson Strut and the Front Shock Absorber and Coil Spring Removal/Installation sections, which illustrate the upper mount and bearing. Mazda genuine parts catalogues for the 2008 CX-9 also list the front shock/strut top mount and integral bearing components. The rear uses a multi-link layout with separate shock and spring, so there are no rear “strut” mounts.

On the CX-9, the front strut mounts do two key jobs: they locate the top of the strut securely to the chassis, and they isolate vibration and road noise so the cabin stays quiet. Built into the mount is a bearing that lets the strut turn smoothly with the steering, helping the big Mazda feel light and precise around town and steady on the open road.

• Common symptoms of worn mounts include clunks over bumps, a creak or springy “twang” when turning the wheel, vague steering, or feathered/uneven front tyre wear.
• Visible cracking in the rubber, a collapsed mount height, or notchiness in the rotation of the strut top are also red flags.

There isn’t a fixed replacement interval in the service schedule, but on Aussie and Kiwi roads many CX-9s benefit from new front mounts somewhere between 120,000 and 200,000 km, or whenever front struts are being replaced. Because the bearing is integral and labour overlaps, it’s smart money to fit new mounts with new struts as a pair (left and right). After any front suspension work, book a wheel alignment to keep tyre wear even and steering true.

During regular servicing, a quick check goes a long way: look for perished rubber, corrosion on the top plate, and listen for noise on low-speed turns. If the top nut or self-locking hardware is removed, use new hardware on reassembly. Quality OEM or reputable aftermarket mounts will keep the CX-9 riding quietly, help it pass WOF/roadworthy checks, and protect those expensive tyres.

Popular questions about 2008 Mazda CX-9 strut mounts

Do 2008 CX-9s have rear strut mounts?
No. The rear of the 2008 CX-9 uses a multi-link suspension with separate shocks and springs, so there are no rear strut mounts. Only the front suspension uses MacPherson struts with top mounts and bearings.

Should the strut mounts be replaced with the front struts?
Yes, it’s widely recommended. The mount’s bearing wears at the same pace as the strut, and the extra labour to change it later is avoidable. Replacing them as a pair helps prevent noise, improves steering feel, and saves on future labour.

How long do front strut mounts typically last?
Driving conditions, loads, and road quality matter, but many CX-9s need mounts somewhere around 120,000–200,000 km. If you notice clunks, steering bind, or uneven tyre wear, have them inspected sooner.
