Parts for your 1999 Mitsubishi Pajero-Exhaust mount

1999 Mitsubishi Pajero Exhaust Mount

Yes, the 1999 Mitsubishi Pajero uses exhaust mounts (rubber exhaust hangers/insulators). This is confirmed by Mitsubishi’s factory Workshop Manual for Pajero/Montero (late 1990s to early 2000s, Exhaust System section), the Mitsubishi ASA electronic parts catalogue, and aftermarket service guides such as Haynes/Gregory’s. These sources show multiple rubber hangers supporting the front pipe, centre section, and rear muffler on both petrol and diesel variants.

On a ’99 Pajero, the exhaust mounts do the quiet achiever’s work: they carry the weight of the exhaust while isolating noise and vibration from the cabin. They also let the system move a little as it heats and cools, so the pipework doesn’t bind or crack. When the rubbers stretch or split, the exhaust can sag, knock the underbody, or stress a flange — none of which is ideal on-road or out bush.

As part of routine servicing, it’s smart to inspect the mounts every 20,000–30,000 km, or any time there’s a rattle over corrugations. Look for perished rubber, elongated holes, torn edges, and rusted brackets. Off‑road use, towing, and heat cycles speed up wear, and oil contamination can soften the rubber. If in doubt, replace them — they’re inexpensive and make a big difference to NVH and exhaust longevity.

Replacement is straightforward with the right approach. Let the system cool fully, support the exhaust with a stand or jack, then lever off the old rubbers and press on the new ones. A dab of silicone spray helps slide them over the pegs. Recheck clearances around the tailshaft, crossmembers, bodywork, and heat shields. If a bracket bolt is removed, snug it to the torque spec in the workshop manual. Many 4x4 owners stick with quality OEM-style rubber, polyurethane hangers can last longer but may transmit a bit more vibration, so choose to suit your comfort and usage.

• Replace mounts in pairs or sets to keep the system level.
• After fitting, start the engine and watch for movement or contact points.
• Keep a spare hanger in the kit for remote travel — they’re small and handy insurance.

Classic signs it’s time: a dull thud on start-up, a tinny rattle over bumps, a droopy tailpipe, or visible cracks in the rubbers. Sort it early and the Pajero’s exhaust will stay quiet, tidy, and happy for the long haul.

Popular questions about 1999 Mitsubishi Pajero exhaust mounts

How many exhaust mounts does a 1999 Pajero have?
Most 1999 Pajeros run three to five rubber hangers depending on engine, wheelbase, and muffler layout. Expect one near the front pipe, one or two around the centre section, and one at the rear muffler. Variants differ, so check the parts catalogue for your VIN.

What are the signs my Pajero’s exhaust mounts need replacing?
Look for a sagging tailpipe, exhaust knocking the floor on bumps, a rattle at idle, or rubber hangers that are cracked, split, or stretched. Excess movement at the muffler when you wiggle it by hand is another giveaway.

Can I drive with a broken exhaust mount?
You might manage short distances, but it’s risky. A failed mount can let the exhaust hit the body or strain joints, which can crack pipes or damage flanges. It’s best to secure it temporarily and replace the mount promptly.
