Parts for your 2006 Nissan Navara-Exhaust mount

2006 Nissan Navara exhaust mount — purpose, care and when to replace

Yes, the 2006 Nissan Navara uses exhaust mounts (also called exhaust hangers or insulators). This is shown in the Nissan Navara D40 Workshop Manual, Section EX – Exhaust System, which illustrates multiple “insulator, exhaust” components along the pipe and muffler. The Nissan FAST electronic parts catalogue for 2006 Navara (D22 and D40) lists these rubber insulators as standard fitment. General repair guides such as the Haynes manual for Nissan Frontier/Navara (2005–2014) also specify inspection and replacement of exhaust hangers during exhaust service. So an exhaust-mount is absolutely relevant to the 2006 Navara.

On a 2006 Navara, the exhaust mounts are the small but mighty rubber insulators that suspend the exhaust from the chassis. They keep the system aligned, soak up vibration, and maintain safe clearances to the body, drivetrain and suspension. By letting the exhaust move slightly without metal-to-metal contact, they protect the manifold, turbo/downpipe joints, gaskets and flex sections from stress and cracking.

Over time, heat, road grime, oil contamination and off-road torsion can harden or crack the rubber. When that happens, the exhaust starts to sag or shift, and knocks on crossmembers, the tub, or the towbar.

• Common signs: rattles over bumps, a dull thud at start-up/shut-down, tailpipe sitting off-centre, or increased cabin vibration at idle.
• Visual clues: torn rubber, perished edges, elongated holes, or a hanger that’s sitting at an odd angle.

Replacement is straightforward and a good add-on during routine servicing. Let the exhaust cool fully, support the pipe/muffler with a jack and timber block, then unhook the old rubber insulators. A spritz of silicone spray helps them slide off and on. Fit quality OEM-equivalent rubbers, or polyurethane if a firmer, longer-lasting option is desired (noting it can pass a touch more vibration into the cabin). Once installed, check tailpipe alignment and clearances to the spare wheel, heat shields and bodywork, and snug up any bracket hardware. Recheck after the first heat cycle if you’ve disturbed clamps.

For Aussie and Kiwi conditions, a quick look at the mounts every service or 10,000–15,000 km is smart, especially if the Navara tows, lives near the coast, or sees corrugations. Replacing tired mounts early is cheap insurance against cracked pipes, broken brackets and annoying exhaust knocks.

• Tip: If one mount has failed, inspect the rest. They often age as a set.

Popular questions about 2006 Nissan Navara exhaust mounts

How many exhaust mounts does a 2006 Navara have?
Most 2006 Navaras (D22 and D40) run several insulators: typically one near the front pipe, one around the mid-section, and one or two at the rear muffler/tailpipe. Exact count varies with cab type, engine, and whether the system is aftermarket.

Is it safe to drive with a broken exhaust mount?
It’ll usually move and rattle, which can damage brackets, flex joints or the muffler, and may let the pipe contact the body or driveshaft under load. Short trips to a workshop are common, but it’s best to sort it promptly to avoid costlier repairs.

Should they upgrade to polyurethane mounts?
Poly mounts can last longer and hold alignment better, handy for off-road and towing. The trade-off is a bit more vibration transfer than soft rubber. For daily driving comfort, quality rubber is often the sweet spot, for durability and control, poly is worth a look.
