Parts for your 2019 Nissan Pathfinder-Exhaust mount

2019 Nissan Pathfinder exhaust mounts: purpose, care, and when to replace

Referencing Nissan’s R52 2019 Pathfinder Factory Service Manual (EX — Exhaust System) and the Nissan FAST parts catalogue for the R52 platform, this model is fitted with multiple exhaust mounting insulators (rubber hangers) supporting the front pipe, centre section, and rear muffler. So yes — exhaust mounts are relevant and used on the 2019 Nissan Pathfinder.

On the 2019 Pathfinder, exhaust mounts do a deceptively big job. They hold the exhaust system at the correct height, isolate vibration so the cabin stays quiet, and allow a bit of movement for heat expansion and engine rock without letting the pipes knock on the body. Each rubber insulator works like a little damper, keeping the muffler and resonator steady while the SUV handles corrugations, towing and daily commuting.

Because they’re rubber, the mounts can harden, crack, or stretch over time — especially with heat, age, and rough roads. When they start to fail, the tailpipe may sit low, there may be a dull thud over bumps, or the cabin can pick up an annoying buzz at certain revs. Left too long, a sagging system can stress joints and flanges, leading to leaks.

As part of servicing a 2019 Pathfinder, it’s smart to inspect the exhaust mounts every service or at least every 20,000–30,000 km. Look for perished rubber, elongated holes, or shiny contact marks where the exhaust has touched the body or subframe. Spritzing the rubbers with a silicone-safe spray can quiet minor squeaks and makes removal easier, but if the rubber is cracked or stretched, replacement is the go.

• Common signs it’s time to replace:
  • Clunking or knocking from the rear over bumps
  • Visible droop or off-centre tailpipe
  • New vibration or droning at cruise
  • Burnt rubber smell (from contact near a hot section)

When replacing, support the exhaust with a stand or jack, swap one mount at a time, and check nearby brackets and heat shields for corrosion. Using OE-spec mounts (or quality equivalents) keeps the system aligned and the cabin calm. If the vehicle tows, sees beach work, or spends time on rough tracks, expect mounts to age faster — build a quick visual check into your routine. Replacing mounts in pairs (left/right or front/rear of the same section) helps maintain even support.

Popular questions about 2019 Nissan Pathfinder exhaust mounts

How often should exhaust mounts be replaced on a 2019 Pathfinder?
There’s no strict time limit, because it depends on heat, kilometres and conditions. Many owners find the original mounts last 80,000–150,000 km. Inspect them at each service, replace at the first sign of cracking, sagging or vibration to prevent stress on flanges and gaskets.

Is it safe to drive with a broken exhaust mount?
Short trips may be possible, but it’s not ideal. A dropped or swinging section can knock on the body, damage sensors or heat shields, and create exhaust leaks. If a mount has failed, reducing driving and getting it fixed promptly is the safest bet.

Are there different exhaust mounts on the Pathfinder?
Yes. The R52 uses several rubber insulators positioned at the front/centre/rear sections, plus metal brackets on the chassis. The rubbers look similar but can differ in size or stiffness by location. Matching position-specific mounts helps maintain correct clearance and ride comfort.
