Parts for your 2018 Ford Ranger-Exhaust mount

2018 Ford Ranger exhaust mount — what it does and when to replace it

Referencing technical sources, an exhaust mount is absolutely used on the 2018 Ford Ranger. The Ford Ranger (PX MkII, 2015–2018) Workshop Manual, Section 309‑00 Exhaust System — General Information, details removal/installation steps that call out detaching and refitting the exhaust hanger insulators. The Ford Global Parts Catalogue (Microcat) for PX Ranger also lists “Insulator – Exhaust System” for this model range (commonly noted as AB39‑5A262‑AD/AC), confirming factory‑fitted exhaust mounts are part of the design.

On a 2018 Ranger, the exhaust mounts (rubber insulators on metal hangers) hold the exhaust in place under the ute, isolating vibration and allowing the system to move slightly as it heats and cools. They keep the tailpipe centred in the bumper opening, prevent knocks on the chassis and crossmembers, and protect the DPF and sensors from stress. Because diesel Rangers run hot—especially those with DPFs—these rubber mounts cop serious heat cycles, off‑road twist, and the occasional beach run splash, so they do age.

Common signs the mounts are tired include:

• Rattles or thuds over bumps, or a buzz at idle/start‑up
• Tailpipe sitting low or skewed in the cut‑out
• Excessive exhaust movement when nudged by hand
• Rubber insulators cracked, oil‑soaked, or elongated

Service advice for a 2018 Ranger exhaust mount:

1. Inspect at every service or 20,000 km, sooner if towing, touring, or off‑road.
2. Support the exhaust with a jack and timber before removing any mount.
3. Mist silicone spray on the insulators to slip them off the pegs without tearing.
4. Replace any insulator that’s cracked, hardened, or stretched—don’t reuse damaged rubber.
5. Use OE or quality high‑temp insulators near the DPF/catalyst, heat here is higher.
6. Check brackets and welds for rust or fatigue, tighten hardware to the workshop spec.
7. After refit, ensure the system is centred with at least a finger’s clearance to heat shields and chassis.

Replacement is a straightforward DIY for many owners, but if the exhaust has sagged or is contacting the body, get a technician to check for bracket fatigue or a cracked hanger. A fresh set of mounts can transform cabin refinement, cutting drumming and squeaks, and it helps protect sensors and the DPF from undue stress—cheap insurance for the long haul across Aussie and Kiwi roads.

How many exhaust mounts does a 2018 Ford Ranger have?

Most PX MkII Rangers use several mounts along the system—typically one near the front/DPF area, one mid‑section, and one or two at the rear muffler/tailpipe. Exact count varies with engine and body style, but there are usually three to four rubber insulators.

Is it safe to drive with a broken exhaust mount?

Short answer: not ideal. A failed mount can let the exhaust shift, knock the chassis, stress welds, or rub through heat shields. That can trigger rattles and, in worst cases, damage sensors or the DPF. It’s best to secure or replace the mount promptly.

What causes Ranger exhaust mounts to fail early?

Heat from the DPF, off‑road flex, towing loads, oil contamination, and age harden or crack the rubber. Beach work adds salt, which can corrode brackets and accelerate wear. Regular inspections and swapping tired insulators keep the system happy.
