Parts for your 2019 Toyota C-hr-Exhaust mount

2019 Toyota C‑HR exhaust mount: what it does and when to replace it

Based on technical sources, the 2019 Toyota C‑HR is fitted with exhaust mounts (also called exhaust hangers/insulators). Toyota’s Electronic Parts Catalogue (EPC) for the C‑HR AX10/AX50 series lists “Insulator, Exhaust Pipe” (PNC 17565) and related support brackets along the exhaust. The Toyota Repair Manual for the C‑HR includes removal/installation steps that involve unhooking and inspecting these rubber insulators, confirming they’re standard equipment on this model.

The exhaust mounts are small, heat‑resistant rubber insulators that suspend the exhaust system from the body. Their job is to isolate vibration, keep the pipe and muffler in the right position, and maintain safe clearance from the subframe, heat shields, bumper and suspension. Good mounts prevent knocks over bumps, protect the flex joint and catalytic converter from undue stress, and keep cabin noise and vibration in check.

For servicing, it’s smart to inspect the mounts at each scheduled service or at least every 15,000 kilometres. Look for perishing, cracking, elongation of the holes, or a sagging tailpipe. Common tell‑tales are a dull thud from the rear, the muffler touching the bumper or crossmember, or extra vibration at idle. If any mount is cracked or stretched, replace it as a set in the affected area to keep the system sitting square.

Replacement is straightforward, but only do it with the exhaust stone‑cold. Support the pipe, then lever the old insulators off their pegs. A dab of silicone spray (avoid petroleum greases) helps the new ones slide on. While there, check bracket bolts, heat shields and clearances, there should be a finger’s width around nearby components. On turbo 1.2‑litre models and other variants alike, using genuine‑spec rubber insulators keeps NVH in the sweet spot. Stiffer aftermarket polyurethane hangers can hold the system tighter but may introduce more cabin buzz.

In Aussie and Kiwi conditions, coastal air and heat cycles age rubber faster. If the vehicle regularly does short trips or towing, expect the rear insulators to work harder. Budget‑wise, the parts are inexpensive and labour is usually quick, doing them before they fail outright prevents collateral damage to the exhaust and bumper.

• Tip: A quick look while the car’s on a hoist for tyres or brakes can catch early perishing before it becomes a rattle.

Popular questions

How many exhaust mounts does a 2019 C‑HR have?
Most 2019 C‑HRs have three to four rubber insulators along the system: typically one near the front pipe, one mid‑section, and one or two at the rear muffler. Exact count can vary with engine and market spec. A parts lookup against the VIN confirms the layout for a given car.

What are common signs the exhaust mounts need replacing?
Listen for knocking over bumps, a buzz at idle, or notice the tailpipe sitting off‑centre. Visual checks may show cracked rubber or stretched holes, and the muffler may touch the bumper or heat shield. If one insulator looks tired, inspect the neighbouring ones as they tend to age together.

Can stiffer aftermarket hangers be used on a C‑HR?
They can, but expect a trade‑off. Stiffer polyurethane hangers hold the exhaust tighter and can help with clearance on modified systems, yet they often increase vibration transmitted into the cabin. For a stock daily driver, genuine‑spec rubber usually gives the best comfort and longevity.
