2018 Nissan Pathfinder Exhaust Mounts: What They Do and When To Replace

Exhaust mounts are absolutely used on the 2018 Nissan Pathfinder (R52). The Nissan service manual for the R52 platform (Exhaust System section) specifies multiple rubber mounting insulators that suspend the front pipe, mid/centre muffler and rear muffler. Nissan’s electronic parts catalogue also lists “Insulator–Exhaust” hangers for this model. That means the Pathfinder relies on these rubber mounts to carry the weight of the exhaust while isolating noise and vibration from the cabin.

On this Pathfinder, the exhaust mounts are small but mighty. Their job is to keep the system correctly positioned under the vehicle, allow a bit of controlled movement as the engine rocks and the pipework heats and cools, and stop the mufflers from thumping the body over bumps. When the rubber perishes or stretches, owners will notice tell-tales like a tinny rattle at idle, a thunk on take-off, or the tailpipe sitting off-centre in the bumper cut-out. Left too long, a sagging exhaust can stress welds, crack joints, or melt nearby trim.

Good practice is to inspect the mounts at each service or at least every 20,000 km, especially if the vehicle tows, does beach runs, or lives in harsher climates. Look for cracks, splits, shine marks where the exhaust has been touching, and mounts that feel overly soft. Any rust on the hanger pegs or bent brackets is also a clue to replace. When swapping them out, support the exhaust with a stand, work only on a cool system, and use a spritz of silicone spray or soapy water to slip the old rubbers off the pegs. A set of exhaust-hanger pliers makes it a doddle.

Replacement is straightforward for a competent home mechanic and usually takes 30–60 minutes. Go with quality OE-spec rubber mounts to keep the factory ride and quietness. Polyurethane hangers can add durability but may pass a bit more vibration into the cabin. After fitting, check clearances to the subframe, heat shields and rear bumper, then snug any brackets and recheck after a short drive. For many Pathfinders there are four to six mounts across the mid and rear sections—if one has failed, it’s smart to replace the set so the system sits square and behaves itself for the long haul.

• Check at every service or 20,000 km
• Replace if cracked, stretched, or causing rattles
• Use OE-spec rubber for best NVH

Popular questions about 2018 Nissan Pathfinder exhaust mounts

How many exhaust mounts does a 2018 Pathfinder have?
Most R52 Pathfinders run four to six rubber mounts spread across the centre and rear sections. Exact count can vary with trim and exhaust layout. A quick visual check on a hoist will confirm what’s fitted to a specific vehicle.

How often should the mounts be replaced?
There’s no fixed interval. Inspect them at each service, many last 80,000–150,000 km. Heavy towing, corrugations, or coastal use can shorten their life. Replace at the first signs of cracks, sagging, or exhaust contact with the body.

Can polyurethane hangers be used instead of rubber?
They can, and they’re tougher, but they may transmit more noise or vibration into the cabin. Owners chasing factory refinement typically stick with OE-spec rubber, those prioritising durability or tighter exhaust control might choose polyurethane.
