2008 Nissan Pathfinder Exhaust Mounts

Exhaust mounts are absolutely used on the 2008 Nissan Pathfinder (R51). The Nissan Pathfinder Electronic Service Manual (R51), section EX (Exhaust System), depicts rubber exhaust mounting insulators and associated brackets across the system, and the Nissan parts catalogue lists these as “insulator – exhaust” components for both the V6 petrol and 2.5 dCi diesel variants. Aftermarket catalogues from major exhaust suppliers also specify direct-fit rubber hangers for this model. So an exhaust-mount is relevant, fitted, and vital to how the Pathfinder’s exhaust is supported and isolated.

On the 2008 Pathfinder, exhaust mounts (rubber hangers/insulators) suspend the exhaust from the chassis, keeping the pipes and mufflers in alignment while soaking up vibration. They stop the system from banging on the underbody, help maintain correct clearances to heat shields and bodywork, and reduce noise and harshness in the cabin. Because they’re rubber, they cop heat, road grime, and the odd knock off-road, over time they harden, crack, stretch, or tear, and the metal brackets can corrode.

As part of routine servicing, these mounts deserve a quick look. A good rule of thumb is to check them at every service or tyre rotation. If the vehicle tows, sees lots of corrugations, or runs a heavy-duty or aftermarket exhaust, inspections should be more frequent. Replacing perished mounts is inexpensive and prevents bigger dramas like split welds, broken brackets, or damaged oxygen sensors from an exhaust that’s flapping about.

• Common signs they’re due: exhaust knock over bumps, droopy tailpipe, new vibration at idle, melted or shiny rub marks on the system or shields, and visible cracks in the rubber.
• Quick tips when replacing: support the exhaust with a stand or jack, change mounts in pairs or as a set for even support, match the orientation of any keyed mounts, and confirm there’s clearance around the diff, spare wheel, towbar, and heat shields.
• A light silicone spray helps slide new rubber insulators on, avoid petroleum-based products on the rubber.

If the brackets are rusty or bent, swap them out as well. After fitting, start the engine, give the system a gentle shake, and make sure nothing touches under load or at idle. A few minutes spent here saves headaches down the track and keeps the Pathfinder quiet, tight, and ready for the next road trip.

Popular questions about 2008 Nissan Pathfinder exhaust mounts

How many exhaust mounts are on a 2008 Pathfinder?
Most R51 Pathfinders run several mounts from the front pipe through the centre section to the rear muffler—typically four to six in total depending on engine, trim, and whether there’s a towbar or aftermarket system. A quick look under the vehicle will confirm the exact count.

Is it okay to drive with a broken exhaust mount?
It’ll usually still move, but it’s not a great idea. A failed mount lets the exhaust sag and swing, which can crack welds, stress flex joints, rattle on the body, or heat nearby components. It’s best to support the system temporarily and replace the mount promptly.

What causes exhaust mounts to fail on the Pathfinder?
Age, heat cycles, oil or fuel contamination, off-road impacts, and the extra mass of towing or aftermarket exhausts all accelerate wear. Once the rubber hardens or tears, the system loses its isolation and can start knocking or vibrating.
