Parts for your 2000 Nissan Bluebird-Exhaust mount

2000 Nissan Bluebird exhaust mount

Exhaust mounts are absolutely fitted to the 2000 Nissan Bluebird. This is confirmed by Nissan’s Factory Service Manual (U14 Bluebird, Section EX: Exhaust System) and Nissan’s Electronic Parts Catalogue listings, which show multiple rubber “insulator” hangers supporting the front pipe, centre section and rear muffler.

On this Bluebird, the exhaust mounts are the rubber isolators that suspend the exhaust under the car, keeping the pipework aligned while soaking up engine movement and road vibrations. They stop the muffler knocking on the body, maintain correct clearances to heat shields and suspension, and cut down on droning inside the cabin. Over time, heat, road grime and ozone harden the rubber, it cracks, stretches, or even tears, letting the exhaust sag or swing about.

Typical signs the mounts are past it include:

• Clunks or tapping over bumps or on start-up
• Visible sagging muffler or crooked tailpipe
• New rattles, droning, or vibration at certain revs
• Perished, split or shiny (overstretched) rubber

Good servicing practice on a 2000 Bluebird is to check the exhaust mounts any time it’s on a hoist—say every 10,000–15,000 km or at each service. A small torch will show up cracking and elongation around the hanger holes. If one mount has failed, the rest are often not far behind, replacing them as a set helps keep the system square and quiet.

When replacing, support the exhaust with a stand or jack and work on a cool system. A dab of silicone spray or rubber-safe lubricant helps the hangers slide off and on. Many Bluebirds use two hangers at the rear muffler and one or more along the centre section—match the new mounts to the original style and hardness. Fresh OEM-style rubber usually gives the best NVH, polyurethane is stiffer and durable but can transmit a bit more vibration. After fitting, confirm the tailpipe sits centred in the bumper cut-out and that there’s finger clearance to heat shields and the rear beam. A quick road test over a few bumps will tell if anything taps.

Pro tip: if the exhaust was previously sagging, check the flex joint and flange gaskets for undue stress, tired mounts can mask other issues.

Popular questions

How many exhaust mounts does a 2000 Nissan Bluebird have?
Most 2000 Bluebirds (U14 sedan) run several mounts: typically one near the front pipe/centre, one around the centre muffler, and two at the rear muffler. Exact count varies with engine and market exhaust layout, but three to four rubber insulators is common.

What are the signs the Bluebird’s exhaust mounts need replacing?
Look for a sagging or crooked tailpipe, knocks over bumps, or a new droning/vibration at certain revs. Up on a hoist, perished or cracked rubber and elongated holes are the giveaways. If one has torn, the rest deserve a close look.

Can polyurethane mounts be used on a 2000 Bluebird?
They can, and they’re tougher, but they’re stiffer than OEM rubber. On a daily driver Bluebird, fresh OEM-style rubber usually keeps the cabin quieter. Poly is fine if longevity or extra support is the priority, but expect a touch more vibration.
