2022 Toyota Land Cruiser (300 Series) Exhaust Mounts

Exhaust mounts are absolutely used on the 2022 Toyota Land Cruiser 300 Series. This is confirmed by Toyota’s technical literature: the Land Cruiser 300 Repair Manual details installation/removal of the exhaust pipe assembly and its supports (rubber hangers/insulators and brackets), and the Toyota Electronic Parts Catalogue for J300 lists “Rubber, Exhaust Pipe Support” and “Bracket, Exhaust Pipe” components for both petrol and diesel variants. Those sources make it clear the exhaust is suspended from the chassis using multiple rubber mounts to control movement and vibration.

On this Land Cruiser, the exhaust mounts do the hard yakka of holding the system in place while isolating vibration from the cabin. They let the exhaust expand and contract with heat, follow the engine and driveline movement over corrugations, and keep critical hardware—catalysts and, on the diesel, the DPF—at the right height and clearance. Good mounts mean fewer rattles, better NVH, and less stress on flanges, flex joints and sensors.

There’s no strict replacement interval, but they should be inspected at every service (around 15,000–20,000 kilometres) or any time the exhaust is removed. Towing, beach work and off-road heat cycles can harden or crack the rubber sooner. Look for perished rubber, elongation of the holes, shiny “glazed” surfaces, or rusted metal brackets and bent hangers. Ensure the tailpipe sits centred in the bumper cut-out and clears the spare and tow gear.

• Common signs of tired mounts: thumps or knocks over bumps, a droning/boomy note at certain revs, tailpipe sitting low or off-centre, vibration at idle or on start-up/shut-down, or heat shields buzzing.

When replacing, let the exhaust fully cool and support it with a stand so weight isn’t hanging off a single mount. A spritz of silicone spray helps the old insulators slide off and the new ones slip on. Use OE or OE-quality high‑temp rubber insulators rather than generic pieces that can alter height and preload. On diesel DPF models, keep the canister orientation and clearances exactly as per factory—mount height changes can affect sensor wiring and heat shielding. Re‑torque brackets to spec and recheck tailpipe clearance after a short drive as the system heat‑soaks.

Fresh, correct mounts keep the Land Cruiser quiet, protect the expensive bits downstream of the turbos, and make the whole rig feel tighter on road and track.

Popular questions about 2022 Land Cruiser exhaust mounts

How often should exhaust mounts be changed?
There’s no fixed schedule. On a 300 Series that tows or sees corrugations, start inspecting every service. Many last well past 100,000 km, but heat, load and off‑road use can shorten that. Replace on condition—cracks, sagging, or excessive movement are the cues.

Can aftermarket polyurethane hangers be used?
They can fit, but they’re usually stiffer and can add cabin vibration. For most Aussie and Kiwi conditions, OE-style rubber insulators balance durability and comfort best, especially on DPF-equipped diesels where NVH and clearance are critical.

What symptoms point to a failed mount versus an exhaust leak?
A failed mount often causes knocks over bumps and a tailpipe that looks off-centre. An exhaust leak usually brings a sharp ticking or hissing and soot marks at a joint. If in doubt, support the system and check each hanger while gently rocking the exhaust.
