Parts for your 2018 Toyota Hilux-Exhaust mount

2018 Toyota Hilux exhaust-mount: what it does and when to replace it

Based on technical sources – namely the Toyota Hilux (AN120/AN130, 2015–2020) repair manual and Toyota’s Electronic Parts Catalogue – the 2018 Hilux is fitted with multiple exhaust mounts (rubber hanger insulators) supporting the front pipe, centre muffler and tailpipe. Aftermarket catalogues for the Hilux platform also list these insulators, confirming they’re standard equipment.

The exhaust-mount’s job is simple but vital: suspend the exhaust under the ute while soaking up engine vibrations and allowing a bit of controlled movement for heat expansion and chassis flex. Good mounts keep the pipework centred in its hangers, maintain the right clearances to the body and undertray, and stop that annoying rattle or thump over corrugations. They’re small pieces of rubber, but they make a big difference to cabin refinement and to the life of the exhaust and brackets.

For a 2018 Hilux that sees daily commuting, towing or off-road work, it’s smart to inspect the exhaust-mounts at every scheduled service. Look for cracks, splits, hardening, stretched/elongated holes, or a sagging tailpipe. If the exhaust knocks on start-up, drones more than usual, or taps the spare wheel or towbar over bumps, the mounts are prime suspects. Coastal living, constant heat cycles and mud can age the rubber quicker, so keep an eye on them if the vehicle lives a hard life.

Replacement is straightforward with the right approach. Let the exhaust cool fully, support the pipe with a stand, and spritz the rubber with silicone spray or soapy water. Exhaust-hanger pliers make it quicker, but a pry bar will do in a pinch. Swapping mounts in pairs or as a set helps keep the system sitting true. Stick with quality OEM-type rubber for factory noise levels, firmer polyurethane mounts can add durability for heavy towing or rough tracks, but may pass a touch more vibration into the cabin.

While under the vehicle, check the steel support brackets and welds, plus heat shields and clamp positions. If an aftermarket exhaust is fitted, make sure the hanger pegs line up naturally with the insulators—no pre-load or twist. Always tighten related fasteners to the specs in the Toyota repair manual. A few minutes of preventative attention here saves hours chasing rattles later.

• Inspect mounts every service (about every 10,000 km/6 months)
• Replace when cracked, hardened or stretched
• Consider tougher mounts for heavy towing or frequent off-road use

Popular questions about 2018 Toyota Hilux exhaust-mounts

How often should the exhaust-mounts be replaced?
There’s no fixed kilometre limit. On a Hilux serviced regularly, they’re simply replaced when inspection shows cracking, hardening, or elongation, or when the exhaust sags or knocks. Vehicles that tow, run corrugations, or see lots of short trips may need new mounts earlier—often somewhere in the 60,000–100,000 km window, but condition is the real guide.

Are polyurethane exhaust-mounts a good idea?
They can be for durability and better control with heavy tow loads or rough tracks. Just note they’re firmer than OEM rubber, so a little extra vibration or low-speed resonance can creep in. Many owners stick with quality rubber for factory refinement, and go poly only where a mount repeatedly fails.

Do all 2018 Hilux models use the same mounts?
Most use similar rubber insulators, but position and count can vary by wheelbase/body (Single, Extra, Double Cab) and exhaust layout. The Toyota EPC shows minor variations across trims and engine specs. When ordering, match to VIN or build plate to be safe.
