Parts for your 2004 Nissan Primera-Exhaust mount

2004 Nissan Primera Exhaust Mount

Yes—an exhaust-mount is absolutely used on the 2004 Nissan Primera (P12). Technical references including the Nissan Primera P12 Workshop Manual (EX – Exhaust section), the Nissan FAST electronic parts catalogue, and the Haynes Nissan Primera 2002–2008 manual all show multiple rubber exhaust mounting insulators and brackets supporting the front pipe, centre section, and rear muffler. These isolators are essential fittings on the vehicle, not optional extras.

On a 2004 Primera, the exhaust-mount (often called a hanger or rubber insulator) keeps the exhaust system correctly positioned under the car while soaking up engine and road vibrations. It lets the pipework expand and contract with heat without banging the body, stops the muffler from sagging, and reduces drumming in the cabin. Typically, there are three to five mounts: one near the front pipe/cat area, one around the centre resonator, and a couple at the rear muffler. Over time, heat, road grime, and oil contamination can harden or crack the rubber, which is when rattles and knocks begin.

• Signs it’s due: exhaust rattles over bumps, a thud on start-up or shutdown, visible perishing or splitting of the rubber, the tailpipe sitting off-centre, or extra vibration felt in the cabin.
• Service tip: inspect the mounts at each service or at least every 20,000–30,000 kilometres, especially if the car sees rough roads, towing, or short-trip city use.
• Replacement: support the exhaust with a jack and wood block, remove the old insulators, and fit new OEM-quality EPDM rubbers. A spritz of silicone spray helps slide them on and off.
• Hardware: check brackets and bolts for rust, replace any weakened metal hangers. Refit to factory height so the system has clearance to the heat shields and rear bumper.
• Pairing: if one rear mount has failed, the opposite side is often close behind—replacing them as a pair helps keep the muffler level.
• Aftermarket note: universal mounts can work, but the wrong stiffness or length can raise boom or let the exhaust contact the body. Stick with mounts specified for P12 where possible.

For a tidy, quiet ride, keeping the Primera’s exhaust-mounts fresh is cheap insurance. Any knock, buzz, or droop at the tailpipe is a prompt to inspect those rubbers before a minor annoyance turns into a cracked joint or a dragging exhaust.

Popular questions about 2004 Nissan Primera exhaust-mount

How many exhaust-mounts does a 2004 Nissan Primera have?
Most P12 models use three to five mounts, depending on engine and body style. Expect a front hanger near the downpipe, a mid hanger by the centre section, and two at the rear muffler. Variations exist between petrol and diesel models, but the layout always includes multiple rubber insulators to carry and isolate the system.

Is it safe to drive with a broken exhaust-mount?
It’ll usually drive, but it isn’t wise. A failed mount lets the exhaust swing and knock, which can stress flex joints, crack welds, melt nearby trim, or strike the road over bumps. If a mount has torn or a bracket has rusted through, it’s best to support the system and sort it promptly.

How often should the mounts be replaced?
There’s no strict interval—condition is the guide. In typical Australian and New Zealand use, mounts often last many years, but heat and age eventually harden the rubber. Inspect at each service, replace at the first signs of perishing, sag, or noise. After any exhaust repair or impact, re-check that all mounts are sound and correctly positioned.
