Parts for your 2014 Isuzu D-max-Exhaust mount

2014 Isuzu D‑MAX exhaust-mount: what it does, why it matters, and when to replace it

Yes, the 2014 Isuzu D‑MAX absolutely uses exhaust mounts. Technical sources such as the Isuzu D‑MAX 2012–2016 Workshop Manual (Exhaust System section) and the Isuzu Genuine Parts Catalogue (Group 15 – Exhaust) illustrate multiple rubber mounting insulators (often called hangers) and brackets supporting the front pipe, muffler/DPF assembly, and tailpipe. That means exhaust-mount components are relevant to this model and should be included in regular servicing.

On this ute, the exhaust mounts do a simple but vital job: they suspend the exhaust under the chassis, isolate vibration, and keep the system correctly aligned so it doesn’t knock on crossmembers, the tub, the spare, or the towbar. Good mounts protect sensitive hardware like the turbo downpipe, catalytic converter and, where fitted, the DPF, by reducing stress on welds and joints.

It’s smart to eyeball the exhaust mounts at each service (or roughly every 10–15,000 km), especially if the D‑MAX tows, sees corrugations, or does beach and bush work. Rubber lives a hard life with heat, road grime and diesel soot, once it hardens or tears, the exhaust can sag, rattle, or shift out of alignment.

• Common signs they’re tired: tailpipe sitting low or on an angle
• Thumps or metallic knocks over bumps or on start-up/shut-down
• New vibration or droning in the cab
• Visible cracks, perished rubber, or stretched hangers
• Fresh witness marks where the exhaust has been touching the chassis or body
• Excess movement when the system is jiggled by hand (engine off, stone cold)

Replacement is straightforward with the ute safely supported and the exhaust stone cold. Support the system with a jack stand, swap one hanger at a time, and use silicone spray to slip the rubber over the pegs. If one mount has failed, it’s often worth doing the set so the exhaust sits true again. Stick with quality OEM‑style rubber, very firm polyurethane can transmit more vibration to the cabin. Always check clearances around the DPF or muffler, spare tyre and towbar, and re‑secure any heat shields. Bracket fasteners should be tightened to workshop‑manual torque values.

For Aussie and Kiwi conditions—towing the boat, gravel roads, and long highway hauls—adding a quick exhaust-mount check after off‑road trips and before WOF/rego time helps prevent rattles and costly cracks later on.

Popular questions about 2014 Isuzu D‑MAX exhaust-mount

How many exhaust mounts does a 2014 D‑MAX have?
Most 2014 D‑MAX variants use several rubber hangers: typically one near the front pipe, one or two around the muffler/DPF section, and one at the tailpipe. The exact count varies with body style (Single/Space/Dual Cab), wheelbase, and whether a DPF is fitted.

Any time the exhaust is replaced or modified, confirm all factory hangers and brackets are refitted so the system sits central and quiet.

Is it safe to drive with a broken exhaust mount?
A short, careful trip may be possible, but it’s risky. A loose exhaust can strike the chassis, stress the turbo/downpipe, or damage sensors and the DPF. If you must move the ute, secure the exhaust temporarily and avoid bumps, then repair properly as soon as possible.

Should I use polyurethane mounts instead of rubber?
Polyurethane can hold the system firmer, but on a daily‑driven D‑MAX it may add cabin buzz. Quality OEM‑style rubber usually gives the best balance of support and comfort. For heavy off‑road or high‑heat setups, choose high‑temp rubber from a reputable brand.
