2002 Nissan Navara (D22) Exhaust Mount — What It Is and Why It Matters

Yes, the 2002 Nissan Navara D22 uses exhaust mounts. Technical references including the Nissan D22 Service Manual (Engine Mechanical – Exhaust System section), the Nissan FAST electronic parts catalogue for D22, and common exhaust catalogues from OEM-equivalent suppliers all show rubber exhaust mounting insulators (often called exhaust hangers or exhaust mounts) positioned along the front pipe, centre muffler and rear/tail section. These mounts suspend the exhaust under the ute and isolate vibration from the cabin and chassis.

On this Navara, the exhaust mount’s job is simple but crucial: keep the pipework correctly aligned while allowing a bit of movement as the drivetrain rocks and the system heats and cools. The rubber insulators soak up vibration and road shock, protecting welds, flanges and sensors, and stopping the muffler from knocking the chassis or towbar.

When the mounts harden, crack or stretch, the exhaust can sag, rattle on take-off, or thud over bumps. Left too long, that extra movement can stress joints, crack brackets, or leak at flanges. As part of routine servicing, it’s smart to inspect all mounts with the vehicle safely raised, looking for perished rubber, torn loops, bent brackets or missing retainers. A torch and a pry with a trim tool or screwdriver will often reveal excessive play.

• Replacement tips: let the exhaust cool fully, support the section you’re working on, lubricate the rubber with silicone spray, transfer any metal sleeves or isolators, and refit in the original orientation.
• Good practice: replace mounts in pairs/sets on the affected section so load is shared evenly, check bracket bolts for correct torque as per the service manual, and confirm tailpipe clearance to the spare, towbar and bodywork.
• Upgrade options: quality OEM-style rubber insulators suit most users. Polyurethane mounts can curb movement on rough tracks but may transmit a bit more vibration.

Service interval-wise, a visual check every service or 10,000–15,000 km is easy insurance, especially on vehicles that tow or see corrugated roads. If there’s a new rattle at idle, a clunk on turn-in, or the tailpipe looks off-centre, the exhaust mounts are a quick, low-cost fix to restore that factory feel. Refer to the Nissan D22 Service Manual for mount locations and bracket fastener specs, and the D22 listings in the Nissan FAST catalogue for the correct insulator types by engine and body configuration.

Popular questions about 2002 Nissan Navara exhaust mounts

How many exhaust mounts does a 2002 D22 Navara typically have?
Most D22 setups use several mounts: commonly one near the front pipe, one or two around the centre muffler, and one at the rear/tailpipe. Exact count varies with engine, wheelbase and exhaust layout. A quick under-vehicle look will confirm the locations on a specific ute.

What are the signs the exhaust mounts need replacing?
Tell-tales include a droopy tailpipe, fresh scrape marks on the muffler or chassis, rubber insulators that are cracked or torn, and rattles or thuds at idle, over bumps or on take-off. If a new exhaust leak appears after a knock off-road, check the mounts first.

Can polyurethane mounts be used on a D22?
Yes, poly mounts can firm up support and control movement for towing or rough tracks. Just note they can pass a touch more vibration into the cabin than soft OEM-style rubber. Many owners run rubber for daily use and go poly where extra support is needed.
