Parts for your 2017 Honda Cr-v-Exhaust mount

2017 Honda CR‑V exhaust mounts (hangers): purpose, service tips, and when to replace

Technical sources confirm the 2017 Honda CR‑V absolutely uses exhaust mounts (also called exhaust hangers/insulators), so the part is relevant to this model. References include: Honda CR‑V 2017–2019 Service Manual (Exhaust System — Removal/Installation), which details supporting the exhaust and sliding it off rubber hangers, Honda Genuine Parts catalogue/EPC diagrams for the 2017 CR‑V (Rear Muffler and Centre/Front Pipe), which list multiple “Exhaust Insulator” components and brackets, and independent service guides such as Haynes/Chilton and workshop information systems (ALLDATA/ProDemand) that specify removal/refit via rubber hangers. These sources show the CR‑V’s exhaust is suspended by several rubber insulators along the mid‑pipe and rear muffler.

On a 2017 CR‑V, the exhaust mounts do a deceptively important job: they hold the exhaust system in the correct position under the car, isolate vibration from the cabin, and allow a bit of movement as the system heats, cools, and flexes. By suspending the pipes and muffler on rubber insulators, they help prevent rattles, knocks over bumps, cracked welds, and undue stress on joints and gaskets.

As part of regular servicing, it’s smart to inspect the exhaust mounts every 20,000–30,000 km or whenever the exhaust is worked on. Look for perished rubber, cracks, elongation of the holes, or sagging that lets the muffler sit low or touch a heat shield. Any metallic clunk at start‑up, a rattle on idle, or tapping over speed humps is a nudge to check these hangers.

• Common signs they’re due: visible cracking or splitting, exhaust sitting off‑centre, knocking against the subframe or body, excess vibration inside the cabin.
• Good practice: replace aged mounts in pairs or as a set along a section, use quality OEM‑equivalent high‑temp rubber, and confirm brackets and heat shields are sound.

Replacement is straightforward for a competent DIYer with stands: let the exhaust cool, support it with a jack, spray silicone lube on the rubber, then slide the hangers off their pegs. Refit is the reverse, aligning the system so there’s clearance around the body and suspension. Always follow torque specs from the service manual for any brackets or clamps you undo. If a mount has failed, also check neighbouring mounts and the muffler’s welded hooks for bends or cracks. Keeping these little rubber insulators fresh helps the CR‑V stay quiet, free of annoying rattles, and kinder on the rest of the exhaust hardware.

Popular questions about 2017 Honda CR‑V exhaust mounts

How often should the exhaust mounts be replaced?
There’s no fixed interval, but inspecting them at each service (or every 20,000–30,000 km) is wise. In Aussie and NZ conditions, sun, heat, and road grime can age the rubber. Replace when there’s cracking, sagging, or if you’re chasing a rattle/knock from the rear.

What are the symptoms of a bad exhaust mount on a CR‑V?
Expect a dull thud over bumps, a buzz or rattle at idle, or the muffler sitting low or off‑centre. You might also hear a knock on cold start as the system shakes briefly. A quick visual check on a hoist usually tells the story.

Can a home mechanic replace the mounts?
Yes, provided proper safety stands are used. Support the exhaust, lubricate the rubber, and slide the hangers off and on. If rusted hardware needs to be undone, follow the workshop manual and re‑torque correctly. When in doubt, a workshop can swap them quickly and cheaply.
