Parts for your 2004 Nissan Navara-Exhaust mount

2004 Nissan Navara exhaust mount

Yes, the 2004 Nissan Navara (D22) uses exhaust mounts. This is confirmed by Nissan’s D22 Factory Service Manual (EX – Exhaust System), which shows rubber mounting insulators supporting the front pipe, muffler and tail section, and by Nissan FAST parts catalogues and common aftermarket catalogues for the D22 that list exhaust hanger rubbers for this model. So an exhaust-mount is absolutely relevant to the 2004 Navara.

The exhaust mounts on a 2004 Navara are the tough little rubber insulators that hold the exhaust up under the ute while letting it flex and move as the engine rocks and the chassis twists off-road. Their job is simple but critical: keep the system correctly positioned, prevent metal-to-body contact, and absorb vibration so there’s less droning in the cabin and less stress on flanges and welds.

On a typical D22 there are multiple mounts — commonly one near the front pipe bracket, one around the centre/muffler area, and one at the tail pipe. Over time, heat, mud, road grime and age can crack the rubber or stretch it, which lets the exhaust sag or knock against crossmembers.

• Common symptoms: clunks over bumps, a droopy tail pipe, new rattles at idle, melted or perished rubber, or stress cracks/leaks forming at joints.
• Inspection interval: have a look at every service (10,000–15,000 km). They’re cheap and easy to check while the ute’s in the air.

Replacement is straightforward with a few basic tools. Let the exhaust cool, support it with a jack stand, and work one hanger at a time. A quick spray of silicone lube helps the old rubbers slide off and the new ones slip on. If a mount stud or bracket is rusty, replace the hardware so the new rubber isn’t fighting a seized fitting. After fitting, make sure there’s good clearance to the spare wheel, leaf springs, towbar and bodywork.

• Choose quality EPDM or OEM-equivalent mounts, polyurethane options can firm things up if the ute tows or sees corrugations often.
• Aftermarket exhausts may need different hanger positions — match the mount style and length to keep the system centred in the tunnel.
• Post-replacement, recheck clamp torque and listen for contact on a short test drive.

Keeping the mounts fresh protects the muffler and pipes, reduces vibration and knocks, and helps the Navara stay quiet and tidy underneath.

How many exhaust mounts does a 2004 Navara have?

Most D22 utes run two to four mounts: typically one near the front pipe bracket, one at the mid/muffler section, and one at the rear. Exact count and style can vary with cab type, wheelbase and whether it’s got an aftermarket exhaust.

What are the signs the mounts need replacing on a D22?

Look for sagging or off-centre pipework, knocks over bumps, increased vibration, perished or cracked rubber, and fresh leaks at flanges from extra movement. If the tail pipe shifts closer to the towbar or bumper, the mounts are likely tired.

Is it safe to drive with a broken exhaust mount?

It’ll usually move under its own steam, but it’s not ideal. A failed mount can let the system swing, stressing other hangers, cracking welds, or contacting the body and wiring. Keep trips short and slow, and sort it promptly to avoid bigger repair bills.
