Parts for your 2010 Isuzu D-max-Exhaust mount

2010 Isuzu D‑MAX exhaust mount

Exhaust mounts (also called hangers or insulators) are fitted to the 2010 Isuzu D‑MAX. This is shown in the Isuzu D‑MAX 2008–2012 Workshop Manual (Exhaust System section), the Isuzu Electronic Parts Catalogue for 4JJ1 models, and common aftermarket catalogues from major exhaust suppliers that list multiple rubber insulators for this model. So yes—an exhaust mount is absolutely relevant to the 2010 D‑MAX.

On this ute, the exhaust mount’s job is to suspend the exhaust system from the chassis while isolating vibration and noise. The rubber insulators let the system move a little as the engine twists, the pipework heats and cools, and the vehicle flexes off‑road. That movement is essential for comfort and longevity—without it, the exhaust would knock on the body, crack at welds, or transfer cabin‑buzz through the floor. Good mounts also keep clearances correct around the tailshaft, spare wheel, towbar and leaf springs, which matters on lifted or heavily loaded D‑MAXs.

As part of routine servicing (every service or roughly 10,000–15,000 kilometres, depending on the service schedule being followed), the mounts should be inspected. Look for perished rubber, splits, excessive sagging, or shiny rub marks where the exhaust has been touching nearby components. Oil‑soaked rubbers age quickly, so any leaks that contaminate the mounts should be fixed and the mounts replaced. Check the metal hanger rods welded to the exhaust and the body brackets for rust, cracks or loose hardware. If one mount has failed, it’s smart to assess the lot—on older systems, replacing them as a set restores proper alignment and reduces future call‑backs.

Replacement is straightforward for a workshop: safely support the exhaust, remove the tired insulator, lubricate the pegs with silicone spray (avoid petroleum products), slide on the new mount, then verify clearances and tighten brackets to the workshop manual torque specs. It’s worth rechecking after a short drive, especially if the vehicle tows, sees corrugations, or runs an aftermarket exhaust, as those uses can accelerate mount wear. Sticking with quality OEM‑style rubber is ideal for daily and touring duty, polyurethane options are tougher but can pass more vibration into the cabin. Solid mounting is a no‑go on this platform.

• Tell‑tales it’s time: knocks over bumps, a droopy or skewed tailpipe, new rattles at idle, or the exhaust tapping the towbar or spare on take‑off.
• Tip: replace suspect mounts in pairs and confirm the system hangs evenly with no contact points throughout its travel.

How many exhaust mounts does a 2010 Isuzu D‑MAX have?

Most Aussie and Kiwi 2010 D‑MAX utes run four mounts: one near the front pipe, one mid‑span, one at the rear muffler and one at the tailpipe. Some body styles or aftermarket systems may add a fifth support. A quick visual under the ute will confirm the exact count on the vehicle.

Will worn exhaust mounts cause a WOF or roadworthy fail?

They can. If the exhaust isn’t securely mounted or is contacting the body, suspension or driveline, that’s typically a WOF/rego fail item. Excess movement can also stress joints and create leaks, which inspectors don’t love. Fresh, intact mounts help keep the system secure and compliant.

Should replacements be OEM rubber or polyurethane?

For everyday driving, towing and touring, OEM‑style rubber mounts give the best balance of durability and comfort. Polyurethane resists heat and oil better and can last longer in harsh use, but it may transmit more vibration into the cabin. Choose based on how the ute is used and the exhaust setup fitted.
