Parts for your 2017 Nissan Pathfinder-Exhaust mount

2017 Nissan Pathfinder exhaust-mount: what it does and when to replace it

Yes, the 2017 Nissan Pathfinder (R52) uses exhaust mounts (rubber exhaust hangers/insulators). This is confirmed in Nissan’s Electronic Service Manual for the R52 platform (EXH – Exhaust System, Removal and Installation), which shows multiple rubber insulators supporting the front tube, centre section and rear mufflers. Nissan’s parts catalogues/EPC also list exhaust “insulator” and “hanger” items for this model, and mainstream aftermarket catalogues carry direct-fit hanger insulators for the 2017 Pathfinder. Put simply, exhaust-mount is absolutely relevant to this vehicle.

The exhaust-mounts are tough rubber isolators that hold the exhaust up and keep it centred under the car while soaking up vibration. They stop the system knocking on the body or suspension and help maintain correct alignment at the flanges and joints. When the mounts age, harden, crack or stretch, owners can cop rattles over bumps, thumps on acceleration, or a droopy tailpipe that looks a bit sad and can stress the welds.

As part of routine servicing, it’s smart to give the Pathfinder’s exhaust-mounts a quick once-over—especially if the vehicle tows, sees gravel roads, or does plenty of short trips. Look for perished rubber, splits, ovalled holes, or mounts sitting on a lean. If the exhaust sits off-centre in the bumper cut-out, that’s a clue the rubber has sagged.

• Common signs it’s time to replace:
  • Rattles or clunks from the rear or centre underbody
  • Exhaust tip sitting lower or skewed
  • Visible cracks, tears or excessive softness in the rubber

Replacement is straightforward for a competent home mechanic: safely raise and support the vehicle, support the exhaust with a jack and wood block, spritz the old hangers with silicone spray, then lever them off the pegs. Fit the new insulators the same way, ensuring each peg is fully seated. If one mount is cactus, replacing the set on that section keeps the height and alignment even. Aftermarket heavy-duty rubber or polyurethane options can be worthwhile for towing or rougher use, but expect a touch more vibration with firmer compounds.

To extend mount life, keep heat shields intact, fix any leaking exhaust joints that overheat the rubbers, and rinse road salt or beach sand off the underbody after trips. A quick check every 10,000–15,000 km is usually plenty.

Popular questions

How many exhaust mounts does a 2017 Pathfinder have?
It typically uses several rubber insulators across the front pipe, centre section and rear mufflers. The exact count can vary with trim and exhaust layout, but expect multiple mounts supporting the system from front to back. A quick visual underneath will confirm the positions.

Can they be replaced at home?
Yes, with basic tools, safe support stands, and some silicone spray, most owners can swap the hangers. The key is supporting the exhaust so there’s no strain on flanges or flex joints. If bolts or brackets are corroded, or if alignment looks off, a workshop visit is wise.

How long do exhaust-mounts last?
It varies with climate, towing and road conditions. Many last 5–10 years, but vehicles that tow, see corrugations, or cop lots of heat cycles may need new mounts sooner. Inspect at each service and change them at the first signs of cracking, sagging or noise.
