Parts for your 2007 Nissan Pathfinder-Exhaust mount

2007 Nissan Pathfinder exhaust-mount

Based on the Nissan R51 Pathfinder Factory Service Manual (EX – Exhaust System) and the Nissan FAST/Electronic Parts Catalogue, the 2007 Nissan Pathfinder uses multiple rubber exhaust insulators (commonly called exhaust-mounts or hangers) and associated brackets to suspend the exhaust. Haynes/Max Ellery workshop manuals covering 2005–2014 models also illustrate these mounts in inspection and removal procedures. So yes, an exhaust-mount is fitted and absolutely relevant to this vehicle.

On the R51, exhaust-mounts isolate engine and road vibration, hold the pipes and mufflers in the right position under the chassis, and maintain safe clearances to the body, tow gear and suspension. They’re small rubber blocks or donuts that live a hard life near heat, road grime and – for many Pathfinders – salt spray from beach runs. Over time they harden, crack or stretch, which can let the exhaust droop, rattle on crossmembers, or stress joints and flanges.

As part of routine servicing, it’s smart to inspect the exhaust-mounts every 10,000–15,000 km or at each oil change. Look for perishing, splits, elongation of the holes, or metal brackets rusting out. If one mount has failed, others are often not far behind. Replacement is straightforward with basic tools: support the exhaust on a stand or jack, spray the old rubbers with silicone lube, lever them off the pegs, then push new mounts on. Do one mount at a time so the system stays aligned, and recheck clearances around the tailpipe, axle and heat shields before lowering the vehicle. If any steel hangers or brackets are corroded, replace them at the same time.

• Typical symptoms: thudding or tinny rattles over bumps, a visibly sagging muffler or tailpipe, exhaust tapping the towbar, and increased vibration in the cabin.
• What shortens mount life: heat from cats and mufflers, oil contamination, coastal exposure, and off‑road articulation that stretches the rubbers.
• Helpful tips: let the exhaust cool fully, use silicone spray (not petroleum grease) on the rubbers, and apply anti‑seize to hanger pegs for the next service.

Keeping the exhaust-mounts fresh on a 2007 Nissan Pathfinder protects sensors and joints, prevents annoying rattles, and keeps the system safely tucked up for towing and off‑road work.

How many exhaust-mounts are on a 2007 Pathfinder?

Most R51 Pathfinders have several mounts spaced from the front pipe through to the rear muffler/tailpipe, typically four to six rubber insulators plus metal brackets. The exact count depends on engine, trim and whether it’s a single or dual tail section. A quick underbody check or a look at the Nissan parts diagram for your VIN will confirm the number.

What are the signs my exhaust-mounts need replacing?

Rattles over bumps, a clunk on start-up or shutdown, the tailpipe sitting off-centre, or seeing cracked/perished rubbers are the giveaways. If the exhaust is touching the chassis, towbar or suspension, the mounts are likely stretched or broken and should be replaced to prevent leaks and sensor damage.

Is it safe to drive with a broken exhaust-mount?

It may drive, but it’s not ideal. A dropped exhaust can strike the body or road, stress flanges and flex joints, and in worst cases lead to a partial detachment. If a mount has failed, drive gently and sort it promptly to avoid bigger repair bills.
