Parts for your 2020 Nissan Pathfinder-Exhaust mount

2020 Nissan Pathfinder exhaust mount — purpose, care and when to replace

Exhaust mounts are absolutely used on the 2020 Nissan Pathfinder (R52). Technical sources including the Nissan Electronic Service Manual for the R52 platform (EXHAUST SYSTEM section) and Nissan genuine parts catalogues identify multiple rubber exhaust insulators/hangers fitted along the centre pipe and rear muffler assemblies. These components are variously listed as “exhaust insulator” or “exhaust hanger” and appear at factory bracket locations to support and isolate the system.

On the 2020 Pathfinder, the exhaust mount’s job is straightforward but vital. Each rubber insulator holds the pipework and mufflers at the correct height, keeps safe clearance from the body, rear bumper and driveline, and soaks up vibration so the cabin stays quiet. Because the exhaust grows and shrinks with heat, the mounts also let it move slightly without clunks or stress, which helps prevent cracks at welds and flanges.

As part of routine servicing, the mounts deserve a quick look. A workshop or switched-on owner will check them at each service interval or around every 20,000 km. The big tell-tales are perished or cracked rubber, stretched holes, sagging exhaust alignment, shiny rub marks on heat shields, and any rattle or thump over bumps. Coastal driving, towing, rough tracks and heat cycles can age the rubber faster, so Pathfinders that work hard should have the mounts inspected more often.

Replacement is straightforward with the right approach. Always let the exhaust go stone cold, support the pipes with a jack and block, and wet the old insulators with silicone spray to slide them off the pegs. Swapping in quality OEM-spec insulators keeps the NVH balance just right. While there, it’s smart to check bracket welds, hanger rods and nearby heat shields, and to confirm the tailpipe sits centred in the bumper cut-out with healthy clearance. If one mount has failed due to age, replacing the set in that area helps keep things even. After refitting, a quick start-up check for knocks and a road test over a few bumps will confirm it’s all sweet.

• Common symptoms: cabin drone or buzz, knocking on start-up/shut-down, tailpipe off-centre, exhaust tapping the body on corrugations.
• Handy tip: a dab of silicone grease on the pegs makes future service easier and reduces squeaks.

Popular questions about 2020 Nissan Pathfinder exhaust mounts

How often should exhaust mounts be replaced on a 2020 Pathfinder?
There’s no fixed kilometre count, but regular inspection at every service is the go. Many last well beyond 60,000–100,000 km, yet vehicles that tow, see rough roads, or live near the coast may need mounts sooner. Replace at the first signs of cracking, sagging or noise.

What are the signs of a failing exhaust mount?
Owners may notice a dull thump over speed humps, a rattle at idle, or the tailpipe sitting low or off-centre. Shiny contact marks on the muffler or heat shields and extra vibration in the cabin also point to tired insulators.

Is it safe to drive with a broken exhaust hanger?
It’s not recommended. A dropped or misaligned exhaust can strain joints, create leaks, melt bumper trim, or damage sensors. Short, gentle trips to a workshop might be possible, but sorting it promptly prevents costlier repairs.
