Parts for your 2017 Toyota Hilux-Exhaust mount

2017 Toyota HiLux exhaust-mount — purpose, care and when to replace

Based on Toyota’s Hilux (AN120/AN130, 2015–2020) repair manual and the Toyota Electronic Parts Catalogue, the 2017 HiLux exhaust system is supported by several rubber exhaust-mounts (also called hangers or insulators) along the pipe and muffler sections. Major Australian and New Zealand aftermarket parts catalogues also list direct-fit exhaust-mounts for this model. That makes the exhaust-mount a relevant, factory-fitted service item on the 2017 Toyota HiLux.

On a HiLux, the exhaust-mount’s job is simple but critical: hold the exhaust at the right height and angle, isolate engine and road vibration from the cabin, and keep clearances to the chassis, underbody and suspension. The rubber construction lets the system move a little as the engine rocks and the ute flexes off-road, without letting the mufflers or tailpipe knock the body. That means less drone, fewer rattles, and longer life for welds and joints.

Because many HiLuxes tow, work hard and see corrugations, the exhaust-mounts cop heat, mud, salt and UV. Over time the rubber hardens, stretches, cracks or tears. A quick look during routine servicing pays off.

• Common signs it’s time to replace an exhaust-mount:
  • Thumps or clunks over bumps or on start-up/shut-down
  • Exhaust sitting low or skewed, or the tailpipe touching the towbar/spare
  • Buzzing or new vibration at idle or on throttle
  • Visible cracks, splits or oily, swollen rubber

Service tips for a 2017 HiLux exhaust-mount:

• Inspect the mounts at every service interval, and after heavy off-road trips, beach work or water crossings.
• Avoid getting oils or solvents on the rubber — they can soften and shorten service life.
• If one mount has failed, check the rest, replacing mounts in pairs or as a set can restore correct exhaust alignment.

Replacement advice:

• Support the exhaust with a stand or jack before removing any mount so weight doesn’t tear the remaining rubbers.
• Wet the new mount with soapy water or silicone spray to slide it on, don’t use petroleum-based lubricants.
• Check metal hanger pins and brackets for rust or bent tabs and correct as needed so the new mount isn’t preloaded.
• After fitting, confirm clearances to the body, leaf springs and driveline, and listen for contact on a short test drive.

Quality OEM-spec rubber mounts suit most daily-driven HiLuxes. If the ute runs heavier exhausts or frequent corrugations, a heat-resistant or heavy-duty mount can help, noting that very stiff rubbers may pass a bit more vibration into the cabin.

Popular questions about 2017 Toyota HiLux exhaust-mounts

How often should HiLux exhaust-mounts be replaced?
There’s no fixed kilometre limit because it depends on heat, load and environment. A good rule is to inspect them at every scheduled service and replace when cracks, elongation or sag are evident. Utes that tow, see corrugations or beach work may need fresh mounts sooner.

Can a worn exhaust-mount damage other parts?
Yes. A sagging or torn mount can let the exhaust contact the body, towbar or suspension, causing rattles, heat damage to trims, or stress on welds and flanges. Replacing a tired mount early is cheaper than chasing broken brackets and split joints later.

Are stiffer aftermarket mounts a good idea?
They can be for heavy off-road or performance use, as they better control movement and heat. Just remember stiffer rubbers can transmit more vibration. For a daily-driven HiLux, OEM-spec mounts usually hit the sweet spot for comfort and durability.
