1997 Nissan Navara (D22) Exhaust Mounts — What They Do and When to Replace Them

Exhaust mounts are absolutely used on the 1997 Nissan Navara (D22). Nissan’s own D22 Service Manual (EX section) specifies multiple exhaust “insulators” and brackets along the system, the Nissan FAST parts catalogue lists the corresponding hanger/insulator components, and popular workshop guides such as Gregory’s Navara 1997–2004 Repair Manual include inspection of exhaust hangers as part of routine servicing. So yes—this ute relies on rubber exhaust mounts to keep the system secure and quiet.

On the ’97 Navara, the exhaust mounts (often called hangers or insulators) suspend the exhaust from the chassis while letting it move slightly as the engine twists and the suspension works. Their job is to maintain clearances, soak up vibration, and stop the pipework and mufflers from knocking the underbody or putting strain on joints and the manifold. Good mounts mean fewer rattles, less drone in the cabin, and a longer-lived exhaust.

Over time, the rubber perishes, stretches, or cracks—especially with heat, oil mist, towing, corrugations, and coastal use. Typical signs the mounts need attention include:

• Rattles or clunks on start-up, take-off, or over bumps
• A drooping tailpipe or misaligned tip
• Excessive exhaust movement by hand or a thud against the chassis
• New exhaust leaks after hits or hard off-road use

Servicing advice for a 1997 Navara owner is straightforward: inspect the mounts every service (about every 10,000 km or 6 months on older utes). Look for splits, elongation of the holes, hardened or oil-soaked rubber, rusty brackets, and loose fasteners. Also check there’s healthy clearance around the pipework—generally a comfortable finger-width or better—to the crossmember, body, and driveline bits.

Replacement is a simple DIY if the vehicle is safely supported on stands. Support the exhaust with a jack and wood block, wet the rubbers with silicone spray, and lever them off with exhaust-hanger pliers or a sturdy pry bar. Fit quality OEM-equivalent rubbers, heavy-duty or polyurethane options can be used for work utes but may transmit a touch more vibration. Replace mounts in pairs on the same section, and snug all bracket bolts to factory spec as per the D22 manual. Afterward, recheck clearances and listen for knocks on a short test drive.

A little attention here saves the muffler, flanges, and manifold from stress, and keeps the Navara feeling tidy on Kiwi and Aussie roads alike.

FAQs

How often should exhaust mounts be replaced on a 1997 Navara?

There’s no fixed kilometre limit—replace on condition. Check the mounts every 10,000 km or 6 months. In hotter climates, with towing, or on corrugations, expect to renew them sooner when the rubber perishes or stretches.

What are the symptoms of a bad exhaust mount on a D22?

Listen and look for rattles, thuds over bumps, or a tailpipe sitting low or skewed. Excess exhaust movement by hand and fresh exhaust leaks after an impact are strong clues the hangers or brackets need replacing.

Can polyurethane hangers be used on a 1997 Navara?

Yes, many owners fit poly for durability, especially on work utes or off-road rigs. Just note they can pass a bit more vibration into the cabin than soft OEM rubber. Choose quality brands and ensure the correct length to maintain clearances.
