Parts for your 1992 Mitsubishi Pajero-Exhaust mount

1992 Mitsubishi Pajero exhaust-mount — what it does, and when to replace it

Exhaust-mounts (rubber exhaust hangers/insulators) are absolutely fitted to the 1992 Mitsubishi Pajero. Technical sources including the Mitsubishi Pajero NH–NJ (1991–1996) workshop manual, the Mitsubishi ASA/CAPS parts catalogue for NH/NJ series, and AU/NZ repair guides such as Gregory’s Pajero manual confirm the exhaust system is suspended from the chassis by multiple rubber insulators. These mounts isolate vibration, allow heat expansion and movement off-road, and keep the pipework and mufflers in correct alignment.

On a ’92 Pajero, the exhaust-mount’s job is to carry the weight of the pipes and mufflers while cushioning the lot from engine rock, drivetrain movement and rough tracks. By letting the system flex a little, the mounts prevent metal-on-metal knocks, keep the tailpipe clear of the body and suspension, and stop harsh vibration from droning through the cabin. They also reduce stress on welds, flanges and the manifold, particularly important on lifted rigs or vehicles that see corrugations and creek crossings.

As part of regular servicing, it’s smart to eyeball each hanger at the rear muffler, centre section and near the transmission crossmember. Rubber ages: it perishes, cracks, hardens or stretches. Oil contamination from leaks accelerates the damage. When a mount gives up, the pipe can sag, bang on the crossmember or rear bar, and you’ll often hear a rattle at idle or over bumps.

Replacement is straightforward with the vehicle cool and safely supported. A shot of silicone spray helps the old insulators slide off the pegs. Swapping them in pairs or as a set keeps the system sitting square. Choose hangers matched to the Pajero’s bracket spacing and load, heavy-duty or polyurethane options can last longer off-road but may transmit a touch more vibration than soft OE-style rubber.

• Inspection interval: every service or 10,000–15,000 km, and after big trips.
• Watch for: cracks, elongation, shiny wear marks where the exhaust is touching, and tailpipe misalignment.
• Refit tips: check 10–15 mm clearance to bodywork, heat shields and towbar, recheck after a couple of heat cycles.

If the Pajero runs a rear bar, long-range tank or aftermarket exhaust, the mounts might need repositioning or a stiffer spec to keep the system off the tank and chassis. Sort the hangers first before chasing noises elsewhere—often it’s the cheapest, quickest win.

Popular questions about 1992 Mitsubishi Pajero exhaust-mounts

How often should the exhaust-mounts be replaced on a 1992 Pajero?
There’s no fixed expiry, but many owners find original-style rubber hangers last several years. Check them at each service and replace as soon as you see cracks, hardening, or stretched holes. Frequent off-road use, towing, and heat will shorten their life, so proactive replacement before a big trip isn’t a bad shout.

Can universal exhaust hangers be used on an NH/NJ Pajero?
Yes, quality universal hangers can work if the hole spacing, thickness and durometer match the Pajero’s brackets and exhaust weight. However, vehicle-specific insulators usually fit neater and keep clearances right, especially around the rear bar, spare and fuel tank.

What are the signs of a failed exhaust-mount on a 1992 Pajero?
Listen for knocks over bumps or a metallic rattle at idle, and look for a tailpipe sitting low or skewed. Underneath, you may see the exhaust touching a crossmember or heat shield, or a mount with torn rubber or elongated holes. Fix it early to avoid cracked welds or damaged flanges.
