Parts for your 2009 Mazda Premacy-Exhaust mount

2009 Mazda Premacy exhaust mount — purpose, care, and when to replace

Yes, the 2009 Mazda Premacy (Mazda5, CR series) uses exhaust mounts. Mazda’s workshop literature (Mazda Global Service Support, CR chassis, Exhaust System—Removal/Installation) shows the centre pipe and rear muffler suspended by multiple rubber insulator hangers and brackets. Independent manuals, such as the Haynes Mazda 5 (2006–2012) exhaust section, also specify inspecting the exhaust hanger rubbers during routine servicing. These mounts isolate vibration, support the mass of the system, and keep the pipework centred so it doesn’t rattle on the body or heat shields.

On this Premacy, the exhaust mounts are small but mighty. They’re rubber insulators that sit between the chassis hooks and the exhaust hangers to soak up movement and stop droning in the cabin. Over time heat, road grime, and ozone harden the rubber, and the holes can elongate. When that happens, the exhaust can sag, thump over bumps, or load up joints and flanges, leading to stress cracks and leaks. That’s why Mazda’s service procedures include removing the system from the hangers for certain jobs and checking the condition of every insulator while they’re there.

Best practice for the 2009 Premacy is to eyeball the mounts at every service and replace any that are cracked, shiny/hardened, or misshapen. If one’s gone, the rest usually aren’t far behind—doing them as a set keeps the silencer sitting straight and the tailpipe clear of the bumper. Use OE-spec rubber insulators (correct size and durometer), going too stiff (e.g., hard polyurethane) can lift noise and vibration inside the car. When swapping them out, support the exhaust with a jack and block, spritz the rubbers with silicone spray, and never twist the pipework against the O2 sensor looms. After refitting, check clearances to the subframe, heat shields, and rear valance, then snug the brackets to workshop-manual torque.

• Tell-tales it’s time: clunks on take-off, exhaust visibly drooping, buzzing at certain revs, or fresh witness marks where the pipe has kissed a shield.
• Service rhythm: quick visual at every oil change, plan replacement around 100–150,000 km or sooner in hot/coastal climates.
• Pro tip: if the rear muffler’s off-centre, try fresh mounts before bending hangers—it often sorts alignment without force.

FAQs

How many exhaust mounts are on a 2009 Mazda Premacy?

Typically four rubber insulator mounts support the centre pipe and rear muffler, with variations by market and trim. The Mazda CR workshop manual diagrams show hangers at the mid-section and two at the rear silencer, plus a forward support/bracket where applicable.

What symptoms point to a failed exhaust mount on a Premacy?

Common signs include a dull thud over bumps, buzzing or droning at certain RPMs, a tailpipe that sits low or skewed, and new rattles against heat shields. Early replacement prevents extra stress on joints and the catalytic converter.

Can universal exhaust hangers be used?

They can in a pinch, but OE-spec dimensions and rubber hardness keep NVH in check and maintain proper clearances. If using aftermarket, match the hole spacing and thickness to the original, and recheck alignment once fitted.
