Parts for your 2009 Toyota Crown-Exhaust mount

2009 Toyota Crown Exhaust-mount

Technical sources, including Toyota’s service literature for the S200-series Crown (2008–2012) and the Toyota Electronic Parts Catalog (EPC), show the 2009 Toyota Crown uses multiple exhaust-mounts (rubber hangers/insulators) to suspend the exhaust front pipe, centre section and rear muffler from the body. So yes—an exhaust-mount is absolutely relevant and fitted to the 2009 Toyota Crown.

On this model, the exhaust-mount’s job is to hold the exhaust system at the right height and angle while isolating vibration. The rubber insulators let the pipework move a touch as the engine rocks and the system heats up, stopping metal-to-metal contact and reducing booming or rattles in the cabin. Good mounts keep correct clearances to the subframe, underbody and bumper, and they protect welds and flanges from stress that can crack pipes over time.

For routine servicing, a quick look at the exhaust-mounts pays off. With the car safely raised and the system cool, check each rubber insulator and bracket. You’re hunting for perished or hardened rubber, splits, stretched holes, missing hangers, bent brackets, and any signs the exhaust is sagging or touching the body. Oil contamination and heat can age the rubber early, and a thump from a speed bump can tear a mount without you noticing.

Replacement is straightforward if you’re set up: support the exhaust with a jack and a block of wood, spritz a little silicone spray on the pegs, and lever the old rubber off. Fit like-for-like quality mounts (OE-spec or a reputable aftermarket). Avoid ultra-soft universals that let the system droop, and be mindful that very stiff polyurethane can add cabin buzz. Refit any brackets, nip up fasteners snug, and check there’s healthy clearance all around. If one mount has given up, the next one often isn’t far behind—replacing in pairs or doing the set can save a repeat job.

As a guide, have the mounts inspected at each service or about every 10,000–15,000 kilometres, and sooner if you notice new rattles, knocking over bumps, a droney note at certain revs, or a tailpipe that’s sitting wonky. Don’t cable-tie a broken mount as a “temporary fix”, it won’t handle the heat. Sort it properly and your Crown will stay quiet, comfy and compliant with roadworthy/WOF expectations.

• Common symptoms of tired mounts: rattles, buzz at idle, exhaust tapping the floor, visible sag, or knocking on take-off.
• Handy tip: a dab of silicone spray or rubber grease makes fitting new insulators far easier.

Popular questions about 2009 Toyota Crown exhaust-mount

How do I tell if my Crown’s exhaust-mounts are on the way out?

Listen for rattles over bumps, a low-frequency drone at certain revs, or a buzz at idle. Visually, look for cracked or stretched rubber, a tailpipe that sits off-centre, or fresh scuff marks where the exhaust has touched the body. If one mount fails, the extra weight can quickly fatigue the next.

Should I choose OEM rubber or polyurethane exhaust-mounts?

OEM-style rubber generally gives the best balance of isolation and durability on a road-going Crown. Polyurethane is tougher and can control movement better, but it may transmit more vibration into the cabin. For daily driving, stick with quality OE-equivalent, for sportier setups, a selective use of stiffer mounts can help, but expect a little more NVH.

Is it safe to drive with a broken exhaust-mount?

Not ideal. A dangling or sagging section can hit the underbody, strain welds and flanges, or crack a joint, leading to leaks and extra noise. It can also breach roadworthy/WOF standards. If a mount fails, drive gently and get it repaired promptly.
