Parts for your 2019 Toyota Hilux-Exhaust mount

2019 Toyota Hilux exhaust mount — what it does and how to look after it

Yes, a 2019 Toyota Hilux is fitted with exhaust mounts (also called exhaust hangers/insulators). This isn’t optional hardware — it’s how the exhaust is supported under the ute. Technical sources that confirm this include the Toyota Electronic Parts Catalogue for the 2015–2020 Hilux (GUN125/GUN126 and related variants), which lists multiple “Insulator, Exhaust Pipe” positions, the Toyota Repair Manual sections for Exhaust Pipe Removal/Installation, which specify unhooking and refitting the hangers and support brackets, and mainstream aftermarket parts catalogues used in AU/NZ workshops (e.g., Mackay Rubber) that supply direct-fit Hilux exhaust insulators for these model years.

The exhaust mounts on a 2019 Hilux are simple, tough rubber insulators that suspend the exhaust system from chassis brackets. Their job is to isolate engine and road vibration, keep the pipework centred in the tunnel, and allow for thermal expansion so the system doesn’t bind or crack. On diesel 1GD-FTV models with a DPF, they also help manage the extra weight and heat cycles through regen events.

For servicing, it’s smart to give the mounts a quick inspection at each service or around every 20,000 km, especially if the ute tows, works off-road, or sees corrugations. Look for perished or hardened rubber, splits, “stretched” holes, a droopy tailpipe, or any metal-on-metal witness marks near the crossmember or spare wheel. A light rattle at idle, a thud over bumps, or a cabin drone that wasn’t there before can all point to a tired insulator or a loose support bracket.

Replacement is straightforward: support the exhaust, lubricate the rubber with silicone spray, and swap the mounts one at a time so alignment stays true. Stick with OE or OE-quality rubber, universal pieces that alter length can throw the pipe out of position and cause knocks. If one mount is badly cracked, replacing the neighbouring mounts at the same time helps keep the system sitting square. Refit any support-bracket bolts to the correct torque, check heat shields, and on DPF models, make sure sensor wiring and hoses aren’t strained after the exhaust is moved.

Keeping the exhaust mounts in good nick protects the Hilux from annoying rattles, prevents stress on the DPF and flanges, and keeps clearance right when the chassis flexes off-road.

• Common signs to replace: cracking, sagging, knocks on take-off, new vibrations, or melted rubber near the DPF area.
• Helpful tip: a quick “tailpipe shake test” on a cool exhaust should show firm support with no hard clunks.

FAQs

How many exhaust mounts does a 2019 Hilux have?
Most 2019 Hilux variants run four to six rubber mounts from the front pipe through to the tail. Exact count depends on cab/bed length, 4x2 vs 4x4, and whether the vehicle has additional brackets around the DPF. A quick visual check under the ute will confirm what’s fitted on a given vehicle.

Can a Hilux be driven with a broken exhaust mount?
It will usually still drive, but it’s not ideal. A missing mount can let the system shift and knock on the chassis, stress joints and sensors, or chafe heat shields and wiring. If a mount has failed, it’s best to support the exhaust and replace the insulator promptly to avoid collateral damage.

How often should Hilux exhaust mounts be replaced?
There’s no fixed interval. Many last 80,000–150,000 km in mixed use, but heavy towing, off-road work, mud, and DPF heat cycles can age them faster. Inspect at every service, replace at the first signs of cracking, elongation, sag, or new exhaust noises.
