2017 Toyota Wish Exhaust Mount: What It Does and When to Replace

Based on technical sources, the 2017 Toyota Wish is fitted with exhaust mounts (also called exhaust hangers or insulators). The Toyota Electronic Parts Catalog (EPC) for the ZGE2#W series lists components such as “Insulator, Exhaust Pipe” and “Bracket, Exhaust Pipe” under the Exhaust Pipe section, and Toyota’s workshop repair manual procedures for exhaust removal/installation specify detaching and refitting the exhaust from rubber hangers. These confirm exhaust mounts are an integral part of the Wish’s exhaust system.

On this model, the exhaust mounts are small but crucial rubber insulators that support the exhaust while isolating vibration and noise from the cabin. They keep the muffler and pipes centred, stop the tailpipe from knocking on the underbody, and help prevent premature cracks at welds and flanges. Typically, several mounts are spaced along the mid-pipe and around the rear muffler area, attached to steel hangers on the exhaust and brackets on the body.

Over time, heat, road grime, and oil contamination age the rubber. A good rule of thumb is to inspect them at each service or at least every 10,000–15,000 km, and more often if the vehicle sees rough roads or towing. Many last years, but any sagging, splitting, or hardening means it’s time to swap them out.

• Tell-tale signs: rattles at idle or start-up, thuds over bumps, a tailpipe sitting off-centre or too low, or visible cracks in the rubber.
• Good practice: replace in pairs or as a set if multiple mounts show age, and check the metal hangers/brackets for rust or bends.

Replacement is straightforward for a competent DIYer with stands and basic spanners. Let the exhaust cool completely, support it with a jack, and lubricate the old mounts with silicone spray to slide them off. Avoid petroleum grease on rubber. Fit quality OEM-equivalent insulators, align the system with adequate clearance from the bumper, heat shields, and suspension, and ensure there’s no preload on the mounts. Tighten related brackets to the repair manual specs. After a heat cycle, recheck clearances and listen for knocks.

Keeping the exhaust properly mounted isn’t just about comfort. A drooping system can stress joints, create leaks, or even risk a WOF fail in NZ or draw attention at rego inspection in AU. A few fresh mounts can restore a quiet, rattle-free drive and protect the rest of the exhaust hardware.

• Popular checks during servicing: condition of rubber insulators, alignment of the tailpipe, integrity of hangers and heat shields.

FAQs

How many exhaust mounts does a 2017 Toyota Wish have?
Most vehicles in the ZGE2#W Wish range use around three to five rubber insulators from the mid-pipe to the rear muffler. The exact count can vary by market and trim. A quick under-car look or a check against the Toyota EPC for your VIN will confirm what’s fitted.

How often should the exhaust mounts be replaced?
There’s no strict interval. Inspect them at every service. Replace when you see cracking, splitting, or if the exhaust sits low or rattles. In hot climates or with lots of short trips, they may age faster, towing or rough roads can accelerate wear too.

Is it safe to drive with a broken exhaust mount?
It may be drivable short-term, but not ideal. A missing or torn mount can let the exhaust swing and bang, strain joints, or melt nearby trim. It’s best to sort it promptly to avoid bigger repair bills or inspection failures.
