Parts for your 2016 Toyota Crown-Exhaust mount

2016 Toyota Crown exhaust mount — what it does and when to replace it

Yes, the 2016 Toyota Crown (S210 series: GRS210/214, AWS210) uses exhaust mounts. Toyota’s Electronic Parts Catalogue (for the S210 Crown) lists multiple “Insulator, Exhaust Pipe Support” items and associated brackets from the centre pipe to the rear muffler. Toyota’s Repair Manual (TIS) exhaust section also details removal/installation of these supports as part of exhaust service. So the exhaust mount is absolutely relevant and fitted to this model.

The exhaust mounts on a 2016 Toyota Crown are those tough rubber insulators and associated brackets that suspend the exhaust from the underbody. Their job is simple but vital: hold the system at the correct height and angle, isolate vibration and exhaust note from the cabin, and allow a bit of movement as the drivetrain twists and the system heats and cools. Good mounts mean less droning, fewer rattles over corrugations, and less stress on flanges, welds, and oxygen sensor wiring.

Over time, heat cycles, road grime, and a bit of oil mist harden or crack the rubber. When they sag, the muffler can knock on crossmembers or heat shields, or the tailpipe may sit off-centre in the bumper. Left long enough, a drooping system can load up joints and lead to premature leaks.

As part of routine servicing, it’s smart to give the mounts a quick once-over:

• Look for perished, split, or shiny-stretched rubber, compare left and right for sag.
• Check brackets for corrosion, especially around the rear muffler hangers.
• Listen for knocks on start-up, over speed bumps, or when shifting from Reverse to Drive.

Replacement is straightforward with the car safely supported. A dab of silicone spray helps slide old insulators off the pegs. Swap like-for-like insulators and torque any bracket fasteners to spec. On hybrids (AWS210), take extra care around additional shielding and wiring. Stick with quality OE or equivalent mounts, the rubber durometer is tuned for NVH on the Crown and cheapies can drone or sag early.

There’s no fixed kilometre interval—many last years—but if one mount looks tired, replace the set in that area to keep the system sitting even. After fitting, confirm tip alignment in the bumper, ensure there’s clearance to the subframe and shields, and check that oxygen sensor leads aren’t tensioned.

Popular questions

How do I know an exhaust mount is failing on a 2016 Crown?
Common giveaways are a dull thud over bumps, a buzz at certain revs, or the tailpipe sitting lower or skewed. A visual inspection usually shows cracked or elongated rubber, or a shiny witness mark where the muffler has been touching a shield or crossmember.

Can universal exhaust hangers be used on the Crown?
They can work in a pinch, but the Crown’s NVH is best with OE-spec insulators. Universal pieces may be too soft or too firm, which can lead to drone or premature sagging. If using aftermarket, match the dimensions and rubber hardness closely.

Do I need to drop the whole exhaust to change the mounts?
Usually no. Most rear and mid insulators can be replaced with the system supported and partially unweighted on a jack stand. Only if brackets are severely corroded or access is tight might sections need to be loosened for room.
