Parts for your 1998 Ford Falcon-Wheel bearings

1998 Ford Falcon wheel-bearings — what they do and when to replace them

Wheel-bearings are absolutely fitted to the 1998 Ford Falcon (AU Series). Technical sources including Ford’s AU Series Workshop Manual (1998–2002) and Gregory’s Repair Manual No. 278 confirm the Falcon uses wheel hub and bearing assemblies at the front and sealed bearings at the rear, depending on live axle or IRS variants. They’re not a delete item — they’re essential hardware that lets the wheels spin freely while carrying the vehicle’s weight.

On the AU Falcon, the front end typically runs a unitised, sealed hub-and-bearing assembly. That means there’s no periodic re-greasing, when it wears out, the whole hub is replaced. At the rear, live-axle models use a sealed bearing pressed onto the axle with a retaining collar and seal, while IRS models use a sealed double-row hub bearing. Either way, the job is inspect-and-replace rather than strip-and-pack.

Why do they matter? Healthy wheel-bearings keep rolling resistance low, steering feels tight, and tyre wear even. When they go off, they can chew out tyres, upset ABS readings, and make the car tramline or wander. It’s the sort of part that works quietly in the background — until it doesn’t.

• Common signs they’re tired: a humming or growling that rises with road speed, a rumble when turning, vague steering, or detectable play when the wheel is rocked at 12 and 6 o’clock.
• Inspection points during servicing: spin each wheel for noise, check for play, look for metal dust around the hub, and keep an eye on ABS warning lights (many AU hubs carry the tone ring).

Replacement tips for a 1998 Falcon: use quality bearings or complete hub units, on live-axle rears, replace the collar and axle seal with the bearing, and torque fasteners to the workshop spec — over-tight or under-tight can kill a new bearing quickly. If an axle nut is staked from factory, it’s generally single-use. After front hub replacement, a quick road test on a quiet bitumen stretch helps confirm any noise is gone. If an IRS rear bearing is being pressed in, a proper press, supports, and the right orientation are vital to avoid early failure.

Maintenance-wise, think of wheel-bearings as “inspect every service, replace on condition.” Many AU Falcons will go well past 150,000 km on originals if wheels are balanced, tyres are kept in good nick, and the car hasn’t copped pothole abuse. When in doubt, check the Ford manual or a trusted local mechanic — it saves tyres, saves fuel, and keeps the big Aussie Falcon feeling right on the open road.

Popular questions about 1998 Ford Falcon wheel-bearings

How do you tell if a 1998 Falcon’s wheel-bearings are failing?
A steady hum or growl that changes with road speed is the classic clue. If the noise gets louder when loading one side (gentle lane change), that side’s often the culprit. Jack the car safely, grab the wheel at 12 and 6 o’clock and feel for play, there should be none. Any grinding when spinning by hand is a red flag.

Are the AU Falcon’s front wheel-bearings serviceable or sealed?
They’re generally sealed hub-and-bearing units on AU models, so there’s no routine re-packing with grease. When worn or noisy, the full hub is replaced. Rears are sealed too, live-axle versions need the bearing, collar, and seal pressed on, while IRS uses a pressed-in hub bearing.

How much does replacement usually cost in Australia or NZ?
Parts and labour vary with front vs rear and live axle vs IRS. A front hub assembly is typically a straightforward swap, rears on live-axle need pressing, which adds labour. As a ballpark, budget a few hundred dollars per corner with quality parts, more if ABS components or additional seals are required.
