Parts for your 1998 Ford Falcon-Exhaust mount

1998 Ford Falcon exhaust-mount

Based on factory documentation for the AU Series (1998) Ford Falcon workshop manual and common Australian parts catalogues for AU exhaust systems, the vehicle is fitted with exhaust mounts (also called exhaust hangers or insulators). These rubber mounts suspend the exhaust under the car at the intermediate pipe and rear muffler, isolating vibration while keeping the system aligned.

On a 1998 Falcon, the exhaust-mount’s purpose is straightforward: hold the pipes and mufflers at the right height, stop metal-to-metal contact with the body, and allow a bit of movement for heat expansion and engine rock. Without good mounts, the system can sag, rattle on speed humps, or stress the catalytic converter and joints.

For servicing, it’s smart to inspect the exhaust mounts at every routine service or tyre rotation. Look for perished rubber, cracks, stretched holes, or mounts that have turned hard and shiny from heat. If the tailpipe looks crooked, the rear muffler knocks on the spare-wheel well, or there’s a dull thud over bumps, the mounts are prime suspects. Replacing tired insulators early prevents broken welds and leaked joints further up the system.

Replacement is usually a simple driveway job. With the Falcon safely on stands and the exhaust cool, spray some silicone or penetrant on the hanger pegs. A pry bar or exhaust-hanger tool helps slide the old rubber off. Match the new mounts to the originals (orientation matters), then push them on fully so the pegs seat in the recesses. If a bracket bolt is involved, nip it up to the manufacturer’s torque spec and re-check alignment so the muffler sits central in the bumper cut-out with adequate clearance to heat shields and the diff.

Quality rubber mounts last years, but heavy towing, rough roads, or repeated heat-cycling can shorten life. Many owners pair fresh mounts with new exhaust clamps or a flex-joint check to keep stress off the headers and cat. A quick post-fit shake test—gently moving the tailpipe side to side—should show a little compliant movement without clunks. If the exhaust still hits the body, add or reposition mounts as per the AU manual guidance.

• Typical service check interval: every 10,000–15,000 km
• Replace if cracked, sagging, hardened, or causing contact/rattles
• Use stands, work on a cold exhaust, and wear eye protection

Popular questions about 1998 Ford Falcon exhaust-mount

How many exhaust mounts does a 1998 AU Falcon typically have?
Most AU Falcons run several rubber mounts—commonly one around the mid-pipe and one or two at the rear muffler, depending on trim and exhaust configuration. Aftermarket systems might add an extra hanger for stability.

What are the signs an AU Falcon’s exhaust mounts need replacement?
Tell-tales include a crooked tailpipe, thudding or metallic tapping over bumps, new vibrations in the cabin, or visible cracks and elongation in the rubber. If the exhaust touches heat shields or the body, the mounts are likely past it.

Can a home mechanic replace the exhaust mounts?
Yes—on stands with basic hand tools, penetrant, and a hanger tool or pry bar. The key is safe support, letting the exhaust cool, lubricating the pegs, and confirming clearances after fitment so nothing fouls under load.
