Parts for your 2006 Nissan Serena-Exhaust mount

2006 Nissan Serena Exhaust Mount

Yes, the 2006 Nissan Serena (C25 series) uses exhaust mounts (also called exhaust hangers or muffler insulators). This is documented in Nissan’s factory service literature for the C25 and in the Nissan FAST Electronic Parts Catalogue, which list rubber “insulator – muffler” components supporting the exhaust at the front, centre, and rear. Those technical sources make it clear the Serena relies on rubber-isolated mounts to suspend the exhaust under the vehicle and keep it properly aligned with the body.

On this Serena, the exhaust mounts are small but mighty. They’re designed to hold the pipework and muffler in position while soaking up vibration and road shock, so the cabin stays quiet and the exhaust doesn’t knock on the subframe or body. The rubber construction provides the flex needed for engine movement and heat expansion, and the steel hanger rods and brackets give the whole lot a secure, tidy fit. When these mounts harden, crack, or stretch, owners often notice rattles over bumps, a tailpipe sitting off-centre, or a thud on take-off. Left too long, a sagging system can stress the flex joint or flange gaskets and lead to leaks or premature corrosion.

As part of routine servicing on a 2006 Serena, it’s smart to eyeball the exhaust mounts every 10,000–15,000 kilometres or at each service. Look for perished rubber, tears, elongation, or oil contamination. Replacement is straightforward: let the exhaust cool, support it with a jack or strap, lube the hanger pegs with silicone spray, and swap the insulators one at a time. Fit quality OEM-equivalent rubber, and replace any corroded brackets or bent hanger rods while you’re there. After installation, make sure the tailpipe sits central in the bumper cut-out with good clearance to heat shields and the rear beam. If any bracket bolts were removed, tighten them to the factory spec noted in the Nissan C25 service manual. Given our Aussie and Kiwi conditions—coastal air, heat, the odd gravel driveway—an annual check helps catch wear early and keeps the Serena quiet, comfortable, and roadworthy.

• Common signs it’s time: exhaust rattle, knocking on bumps, droopy tailpipe, new vibration at idle, or visible cracks in the rubber.
• Typical time and cost: quick job, low-cost parts, plan 15–30 minutes per mount.

How many exhaust mounts does a 2006 Nissan Serena have?

Most C25 Serenas run several mounts spread along the system—typically a front support, one or two mid mounts, and at least one rear mount at the muffler. Exact count can vary by trim, wheelbase, and exhaust layout. A quick underbody look or a check against the Nissan parts catalogue for the specific VIN will confirm the set.

Can a home mechanic replace the exhaust mounts?

Usually, yes. With the car safely supported, a spray of silicone lube, and basic hand tools, the rubber insulators can be pried off and swapped. The key is to support the exhaust so there’s no strain on the flex joint, and to refit mounts so the pipe sits centred with good clearance. If brackets are rusty or a hanger rod is cracked, it’s worth handing it to a workshop.

Is it safe to drive with a broken exhaust mount?

Short answer: not ideal. A failed mount can let the exhaust sag or swing, causing knocks, heat damage to nearby parts, or stress on joints that can lead to leaks. It can also attract attention at WOF or during a roadworthy inspection. If a mount breaks, it’s best to sort it promptly to avoid bigger repair bills.
