Parts for your 2008 Nissan Navara-Exhaust mount

2008 Nissan Navara Exhaust Mount

Technical sources confirm the 2008 Nissan Navara (D40) is fitted with exhaust mounts (also called exhaust hangers or insulators). The Nissan D40 Navara/Frontier Electronic Service Manual (EX – Exhaust System section) shows the exhaust assembly suspended from the chassis with rubber insulators, and the Nissan FAST parts catalogue for D40 lists “Insulator – Exhaust” as serviceable items. Major AU/NZ aftermarket catalogues also carry replacement exhaust mount rubbers for the 2008 Navara, underscoring that they’re standard equipment.

On a Navara, these mounts keep the exhaust system secure while isolating vibration. They stop the muffler and pipework from knocking on the underbody, help maintain correct alignment to the turbo/downpipe and catalytic converter, and let the exhaust move slightly under torque, corrugations, and heat expansion without transmitting harshness into the cabin.

As part of routine servicing, it’s smart to inspect the exhaust mounts. Rubber hardens, cracks, or stretches over time—especially on utes that tow, spend time off-road, or cop a lot of heat cycles. Tell-tale signs include rattles or thuds over bumps, a drooping tailpipe, exhaust contact marks on crossmembers or the towbar, and a buzz at idle that wasn’t there before. If any mount is torn or sagging, replace it—ideally in pairs or as a set—to keep support even along the system.

Replacement is straightforward for most DIYers. Let the exhaust cool fully, support it with a jack and stand, then lubricate the old mount with silicone spray and slide it off the pegs. Fit the new rubber the same way and check the exhaust clears heat shields, brake lines, and the rear bumper. While you’re there, inspect metal brackets for cracks and surface rust, and make sure clamps and flanges are tight and leak-free.

For Navaras doing heavy work or tackling corrugations, check the mounts at every service interval. If fitting an aftermarket cat-back, ensure the kit uses the factory hanger positions and quality high-temp rubbers. Fresh mounts are inexpensive insurance against exhaust damage and annoying cabin noise.

• Check mounts every service or 10,000–15,000 km.
• Replace stretched, cracked, or oil-soaked rubbers promptly.
• Support the exhaust before removing any mount.

Popular questions about 2008 Nissan Navara exhaust mounts

How often should the exhaust mounts be replaced on a 2008 Navara?
There’s no fixed kilometre interval. Inspect them at each service and replace on condition. Many last 5–10 years, but towing, off-roading, and heat can shorten that.

What are the symptoms of a failing exhaust mount on a Navara?
Common clues include a rattle or thud over bumps, a buzz at idle, the tailpipe sitting low or off-centre, and visible cracks or elongation of the rubber.

Can a home mechanic replace the exhaust mounts?
Yes. With the vehicle safely supported, some silicone spray, and basic hand tools, most hangers can be swapped at home. Always work on a cold exhaust and support it before removing mounts.
