Parts for your 2006 Toyota Crown-Exhaust mount

2006 Toyota Crown exhaust mount

Exhaust mounts are absolutely fitted to the 2006 Toyota Crown. Toyota’s Electronic Parts Catalog for the S180 series (2003–2008) lists multiple “Insulator, Exhaust Pipe” rubber hangers and related brackets, and the factory workshop manual covers inspection of exhaust pipe supports within the Exhaust Pipe and Muffler section. That confirms this model uses rubber isolator mounts to suspend and stabilise the exhaust.

On the Crown, the exhaust mounts are tough little rubber insulators that hold the pipework and mufflers at the correct height while soaking up engine and road vibration. Their job is to keep the exhaust clear of the body, heat shields and suspension, stop rattles, and protect the welds and flanges from fatigue. When they age, harden or crack, the exhaust can sag or knock—never ideal on a quiet, refined sedan like a Crown.

As part of regular servicing, it’s smart to give the mounts a quick once-over. Every 20,000–30,000 km (or at each oil service), check for perished rubber, splits around the eyelets, elongation, or shiny contact marks on the exhaust and underbody that hint at movement. In coastal or high-heat use, inspect a bit more often. The mounts don’t have a fixed replacement interval, they’re changed on condition.

When replacing them, support the exhaust with a jack and a soft block, then swap hangers one at a time so the system stays aligned. A spritz of silicone spray helps the rubber slide off and on without tearing. Stick with OE-spec rubber for the best noise and vibration control, stiffer polyurethane can suit heavy aftermarket systems but may transmit more cabin buzz. After refitting, make sure the tailpipe sits centred in the bumper cut-out, there’s adequate clearance to the body, and all brackets are tight to spec. If a mount has failed, check the neighbouring ones and any heat shields while you’re there—they tend to age together.

• Tell-tale signs: metallic rattles on start-up, thumps over bumps, a droopy tailpipe, or new vibrations at idle.
• Best practice: replace mounts in pairs or as a set along the affected section to keep the exhaust sitting true.

Popular questions about 2006 Toyota Crown exhaust mounts

How often should the exhaust mounts be replaced on a 2006 Toyota Crown?

They’re replaced on condition rather than time. Inspect them at each service or every 20,000–30,000 km. If the rubber is cracked, hardened, stretched, or the exhaust is sagging or knocking, it’s time to swap them.

In hotter climates or with frequent short trips, the rubber can age faster. Keeping an eye on them prevents stress on flanges, flex joints and welds.

What are the signs an exhaust mount has failed on a Crown?

Common giveaways include a drooping tailpipe, metallic rattles on start-up, thumps over speed bumps, or fresh vibration in the cabin. You might also spot elongated hanger holes or shiny rub marks where the exhaust has touched the body.

If one mount has gone, check the rest along the system, plus the heat shields and brackets.

Can polyurethane exhaust hangers be used instead of rubber on the Crown?

Yes, but choose carefully. Polyurethane hangers are stiffer and can help support heavier aftermarket exhausts, yet they can pass more vibration into the cabin. For a stock Crown aiming for factory refinement, OE-style rubber usually gives the best comfort.

If you do go poly, match the length and angle to maintain correct exhaust alignment and clearance.
