Parts for your 1988 Mitsubishi Pajero-Exhaust mount

1988 Mitsubishi Pajero exhaust mount — purpose, servicing and replacement

Yes, an exhaust mount is used on the 1988 Mitsubishi Pajero. Technical sources such as the Mitsubishi Factory Service Manual for the L040-series Pajero/Montero (Group 15: Exhaust System), the Mitsubishi ASA electronic parts catalogue, and popular workshop guides (Gregory’s/Haynes covering 1983–1991 models) all show multiple exhaust hanger brackets and rubber insulators supporting the system along the chassis. So it’s a relevant, standard component on this model.

The exhaust mounts (often called hangers or insulators) keep the Pajero’s exhaust suspended, allow a bit of movement, and isolate vibration so it doesn’t buzz through the cabin. They hold the pipework, resonator and muffler in the right place under the floor, maintaining clearance to the body, drivetrain and rear axle. On a 4x4 that sees corrugations, ruts and beach runs, good mounts also protect welds and flanges from stress by letting the system flex as the chassis and engine move.

As part of regular servicing, they’re a quick visual check. Every 10,000–15,000 kilometres (or each service), look for perished rubber, cracks, elongation of the holes, or rusty brackets. After off-road or salt exposure, give them an extra once-over—NZ WOF or Aussie roadworthy inspections can ping a droopy exhaust or a mount that’s torn.

Replacement is straightforward and affordable. Support the exhaust with a stand or jack, spritz the old rubbers with silicone spray or penetrant, and lever them off the pegs. Fit OEM-spec rubber insulators (or quality equivalents), avoid mounts that are too stiff, as they can transmit vibration into the cabin. Reuse heat shields and check nearby hardware like clamps and gaskets. Tighten bracket fasteners to the service manual torque settings, and ensure the system sits centred with even clearance around the body and crossmembers.

• Common signs they’re due: rattles over bumps, thuds on start/stop, a droopy tailpipe, exhaust touching the towbar or body, and fumes from stressed joints.
• Handy tips: replace mounts in pairs on the same section, keep a spare in the tool kit for trips, and rinse underbody after beach work to slow corrosion.

How many exhaust mounts does a 1988 Mitsubishi Pajero have and where are they?

Most 1988 Pajeros use several rubber mounts spaced along the system—typically one near the front pipe support, one around the centre section, and two at the rear muffler/tailpipe. SWB vs LWB and engine type can change the exact count and bracket style, but expect three to five in total.

How often should exhaust mounts be replaced?

There’s no fixed interval. Inspect at each service and replace when cracked, perished, stretched or if the exhaust sits off-centre or knocks. In harsh use (off-road, coastal), they may need attention every 2–3 years.

Can universal exhaust hangers be used on a 1988 Pajero?

Yes, in a pinch. Choose the correct length and thickness so the exhaust sits at factory height with enough movement. For heavy 4x4 use, go for quality rubber insulators matched to the original bracket geometry rather than overly stiff polyurethane, which can increase cabin vibration.
