2007 Toyota Highlander exhaust-mount: purpose, fitment and servicing tips

Yes, an exhaust-mount is used on the 2007 Toyota Highlander. Factory literature shows multiple rubber insulator “hangers” supporting the exhaust system. The Toyota Repair Manual for the 2007 Highlander (Exhaust System section) details hanger removal/installation, and the Toyota Electronic Parts Catalogue (EPC) lists the exhaust pipe hanger insulator and brackets for the front pipe, centre section and rear muffler. General service manuals covering 2001–2007 Highlander/Kluger platforms also illustrate these mounts and their inspection points.

On this model, the exhaust-mounts (rubber insulators) keep the exhaust suspended under the body, isolate vibration, and maintain correct clearances to the floorpan, heat shields and suspension. By letting the pipework “float” slightly, they prevent harshness in the cabin and reduce stress on welds, catalytic converters and the flex joint. If a mount perishes or tears, the system can sag or shift, leading to knocks over bumps, rattles at idle, or the tailpipe sitting off-centre in the bumper cut-out.

• Common signs they’re due: thudding or clunks from the rear, extra drone, visible cracks or hardening of the rubber, shiny rub marks where the exhaust has contacted a crossmember, and a droopy muffler.
• Inspection rhythm: have them checked at each service (around every 10,000–15,000 km) or after rough-road trips. Heat, age and road grime gradually stiffen and crack the rubber.

Replacement is straightforward and low cost. Support the exhaust with a jack and timber block, then lubricate the rubber with silicone spray and slide it off the hanger pegs. Swapping mounts in pairs or as a small set helps keep alignment even. Brackets should be inspected for corrosion and tightened to spec after refit. If the system was striking a heat shield, re-shape or re-secure the shield while you’re there. Choosing quality OEM-equivalent rubber (correct hardness) maintains proper isolation, overly soft mounts can let the system swing, while very hard ones can transmit vibration.

• Handy tips: work on a cool exhaust only, use penetrant on stubborn brackets, a small pry bar helps, refit with a dab of high-temp silicone grease on the pegs for next time.
• Fitment notes: Highlander/Kluger variants (4-cyl or V6, FWD or AWD) use several mounts from the front pipe back to the rear muffler, count and match before ordering.

Popular questions

How many exhaust-mounts does a 2007 Toyota Highlander have?
Most 2007 Highlanders have three to five rubber insulator mounts, depending on engine and exhaust layout. V6 and AWD variants often have an extra hanger around the centre or rear section. A quick look under the vehicle will confirm the exact count.

What type of exhaust-mount fits a 2007 Highlander?
It uses rubber insulator “donut” style hangers sized to the factory hanger pegs. Match by VIN or compare dimensions from the existing parts, the hanger rod diameter on Toyotas is commonly around 10–12 mm, but stick with OEM or a known-quality equivalent for the right hardness and fit.

Is it safe to drive with a broken exhaust-mount?
It might still drive, but it’s not recommended. A missing or torn mount lets the exhaust swing and bang, which can damage welds, O2 sensor wiring and the flex joint, and may cause rattles or heat-related issues. Replacing the mount promptly is cheap insurance against larger repairs.
