Parts for your 2019 Isuzu D-max-Exhaust mount

2019 Isuzu D‑Max Exhaust Mount

Yes, the 2019 Isuzu D‑Max uses exhaust mounts (also called exhaust hangers or insulators). Technical references that confirm this include the Isuzu D‑Max Workshop Manual for the TFR/TFS platform (2012–2020) in the Exhaust System section, the Isuzu Electronic Parts Catalogue listing rubber insulators and hanger brackets for the muffler and tailpipe, and common aftermarket catalogues that list D‑Max exhaust hanger insulators for 2017–2020 diesel variants. So, exhaust mounts are absolutely relevant on a 2019 D‑Max.

On this ute, exhaust mounts are the small but mighty rubber insulators and metal brackets that suspend the exhaust under the chassis. Their job is to isolate vibration, control movement as the exhaust heats and cools, and keep the DPF, muffler and tailpipe sitting where they should without knocking on the floorpan or rear bar. A typical 2019 D‑Max will have multiple mounts spaced along the system, with positions varying slightly between cab‑chassis and pickup bodies.

Good mounts mean a quieter cabin, less stress on the flex joint and DPF, and fewer chances of cracked welds. Worn or perished mounts let the system sag or shift, which can cause rattles over corrugations, a thud on take‑off, or contact with crossmembers and heat shields. If the tailpipe looks crooked, the rear muffler droops, or there’s a chattery vibration at idle, the mounts are worth a look.

• Inspection: check at every service (10,000–15,000 km), or sooner if towing, off‑roading, or after an impact.
• What to look for: cracked or split rubber, squashed or oil‑soaked insulators, rusty or bent brackets, missing retainers, and exhaust misalignment.
• Replacement tips: safely support the exhaust, spray silicone lube on the pegs, lever the old insulator off, and fit quality OEM‑spec rubber or polyurethane. Refit brackets and tighten to workshop‑manual torque specs.

While you’re there, check heat shields, hanger welds on the muffler, and the DPF support bracket. On high‑kilometre D‑Max utes, replacing all mounts as a set can restore alignment and stop recurring knocks. For vehicles that see beach work or mud, consider more frequent inspections to stay ahead of corrosion and rubber ageing.

Popular questions about 2019 Isuzu D‑Max exhaust mounts

How many exhaust mounts does a 2019 D‑Max have?
Most 2019 D‑Max models run several rubber insulators from the mid‑pipe to the tail, typically three to four plus brackets. Exact count and location vary with cab‑chassis vs pickup and market‑specific DPF hardware. A quick look under the ute or a check of the VIN in the parts catalogue will confirm.

When should the exhaust mounts be replaced?
There’s no fixed interval, replace when rubber is cracked, torn, sagging, or if there are knocks, rattles, or a crooked tailpipe. As a rule of thumb, inspect at each service, and sooner after off‑road trips, deep water crossings, or if the exhaust has taken a hit.

Is it safe to drive with a broken exhaust mount?
It’s not ideal. A missing or failed mount can load up the flex joint, stress the DPF and muffler welds, and let the system hit the body or axle. If something’s failed, drive gently and get it sorted promptly. Temporary ties are only to limp to a workshop, not a long‑term fix.
