Parts for your 2009 Nissan Navara-Exhaust mount

2009 Nissan Navara Exhaust Mount

Yes, the 2009 Nissan Navara (D40) uses exhaust mounts. Technical references like the Nissan Navara D40 Factory Service Manual (Exhaust System section) and the Nissan genuine parts catalogue for D40 model years, including 2009, show multiple rubber hanger insulators/mounts fitted along the exhaust to support the front pipe, muffler and tail section. These mounts are absolutely relevant to any exhaust service on this model.

The exhaust mount’s job is simple but crucial: it holds the exhaust up, isolates vibration, and lets the system move a touch as it heats and cools. On a Navara that tows, tours, or sees a fair bit of gravel and corrugations, these rubber hangers cop plenty of flex. Good mounts keep the tailpipe centred, stop the muffler knocking the underbody, and protect welds, flanges and the turbo/manifold from stress by allowing controlled movement.

As part of routine servicing on a 2009 Navara, it’s smart to inspect the exhaust mounts whenever the ute’s on a hoist. Look for perishing, cracks, hardness, or elongated holes in the rubber. Signs they’re on the way out include:

• Exhaust rattles on start-up or over bumps
• Tailpipe sitting off-centre in the bumper cut-out
• A dull knock from the rear under load or on rough roads
• Visible sagging of the muffler or pipework

Replacement is straightforward. Let the system cool, support the exhaust with a stand or jack, and spray a silicone-safe lubricant on the hanger pegs. Pop the old insulators off, slide new quality rubber (or suitable heavy-duty) mounts on, and make sure the exhaust sits naturally with good clearance to the chassis, spare, towbar and heat shields. On higher-kilometre or hard-working Navaras, swapping them in sets helps keep alignment even.

Service tips for longevity:

• Check mounts every service (10,000–15,000 km), and after big off-road trips or water crossings
• Avoid oil contamination on the rubber, clean off diesel or underbody sprays
• If fitting a heavier aftermarket system, consider reinforced or OE-quality mounts, not ultra-hard options that can transmit vibration
• Inspect the metal hanger rods and brackets for rust or cracks at the welds

They’re a low-cost part that can save chasing annoying knocks and protect the rest of the exhaust. Most DIYers can do each mount in 10–30 minutes with basic tools.

What are the signs the 2009 Navara’s exhaust mounts need replacing?

Common giveaways are rattles at idle or on corrugations, the tailpipe sitting off-centre, a thud from the rear over speed humps, or visible sag in the muffler. Cracked or rock-hard rubber, or stretched holes in the insulator, also point to replacement time.

How often should the exhaust mounts be checked?

Have a look every service (about 10,000–15,000 km), and sooner if the ute tows, does beach work, or sees a lot of rough roads. After deep water crossings, check them once everything’s dry, as water and grit can accelerate rubber ageing.

Can heavy-duty or polyurethane mounts be used on a D40?

Yes, but choose carefully. Heavy-duty options can help with added exhaust weight, yet overly stiff mounts may increase vibration in the cabin. For most daily and touring use, OE-quality rubber insulators balance support and comfort well.
