Parts for your 2017 Nissan Serena-Exhaust mount

2017 Nissan Serena exhaust mount: purpose, checks, and replacement tips

Based on Nissan’s technical documentation for the C27-series Serena (2016–) — specifically the Exhaust System section of the workshop manual and the Nissan FAST electronic parts catalogue, which lists “insulator–exhaust” components for the C27 — the 2017 Nissan Serena is fitted with exhaust mounts (rubber hangers). These mounts support the exhaust pipes and mufflers and are absolutely relevant to this model.

The exhaust mounts on a Serena do a quiet but vital job: they hold the exhaust at the right height and angle, isolate vibration from the cabin, and stop the system from knocking the underbody or rear bumper. They also help maintain correct clearances around heat shields and suspension, and reduce stress on joints, flanges, and the catalytic converter during engine movement and road bumps.

For servicing, exhaust mounts are a quick visual check that pays off. Rubber insulators naturally harden and crack with age, heat, and road grime. Coastal conditions in Australia and New Zealand can speed up deterioration, and oil contamination can swell or soften the rubber.

• Common signs they’re due: a droopy tailpipe, thuds over bumps, buzzing or rattling at idle, burnt bumper trim from poor clearance, or visible splits in the rubber.
• Typical locations: along the mid-pipe and at the rear muffler, with multiple mounts sharing the load.

Good workshop practice for the Serena includes supporting the exhaust on a jack stand before removing any mount, then easing the rubber off its pegs with silicone spray. Avoid levering directly on thin-walled pipes or the muffler skin. If one mount has failed, it’s smart to assess the set — uneven support can crack welds or stress flanges. When refitting, centre the tailpipe in the bumper cut-out and check all clearances with the vehicle at ride height. After a heat cycle, a quick recheck for contact noises is worthwhile.

• Service interval guidance: inspect at every routine service (about 10,000–15,000 km), replace on condition rather than time alone.
• Part choice: quality OEM-spec rubber insulators are recommended for the right hardness and durability, universal hangers can work if sized correctly but may alter height or NVH feel.

Keeping the Serena’s exhaust mounts healthy helps the whole exhaust system last longer, keeps noise down, and prevents nuisance knocks that can be mistaken for suspension issues.

How often should exhaust mounts be replaced on a 2017 Nissan Serena?

They’re condition-based items. A check every service (roughly 10,000–15,000 km) is sensible. Replace when rubber shows cracking, sagging, separation from the metal sleeve, or oil/heat damage, or when the exhaust sits off-centre or knocks.

What symptoms point to a bad exhaust mount on a Serena?

Rattles at idle, thuds over speed bumps, a tailpipe sitting low or skewed in the bumper, or visible splits in the rubber. In some cases there may be a faint exhaust leak noise if the system is stressed at a joint.

Can universal hangers be used on this model?

Yes, if the hole spacing and thickness match. However, using OEM-spec mounts usually preserves the intended ride height and vibration isolation. Mismatched hardness can cause extra cabin buzz or let the system sit too close to the bumper.
