Parts for your 2004 Ford Falcon-Driveshafts

2004 Ford Falcon driveshafts

Yes, driveshafts are absolutely used on the 2004 Ford Falcon. Technical sources including the Ford BA Falcon Workshop Manual (Ford Australia, 2002–2005), Gregory’s Service and Repair Manual for BA/BF models, and Max Ellery’s BA–BF manual confirm the BA-series Falcon is rear-wheel drive with a propeller shaft (tailshaft) running from the transmission to the rear differential. Sedans feature Control Blade independent rear suspension with CV half-shafts to each wheel, while many utes use a live rear axle (no rear CV half-shafts) but still rely on the tailshaft. Either way, the car needs a driveshaft to get engine torque to the rear wheels.

On a 2004 Falcon, the tailshaft’s job is simple but critical: transfer power smoothly while coping with suspension and drivetrain movement. Many BA sedans use a two-piece tailshaft with a centre support bearing to keep vibrations low. In IRS sedans, the rear axles are CV-type half-shafts that manage wheel travel without binding. When everything’s healthy, it’s quiet, smooth, and drama-free.

As part of routine servicing (every 15,000 km or 12 months is a good rule of thumb), a quick driveline check pays off. Look for:

• Free play or “red dust” at universal joints, and cracking or sagging of the centre support bearing rubber
• Torn CV boots on IRS half-shafts and any sling of grease nearby
• Surface rust at yokes/flanges, missing balance weights, or dented tubes
• Vibration or shudder on take-off, a clunk when selecting drive/reverse, or a speed-related hum

If replacement’s on the cards, marking the tailshaft orientation to the flanges before removal helps preserve balance. Follow the workshop manual for bolt torque and threadlocker use, and don’t mix-and-match components between shafts. If the centre bearing is perished, replacing it and checking balance as an assembly is the tidy way to go. For IRS cars, swap any split CV boots early to save the joint, if the joint’s already noisy or gritty, fit a quality replacement. After any driveline work, a road test for vibrations and a quick re-check of fasteners once it’s heat-cycled is smart practice.

Lowered Falcons, heavy towing, or hard launches can accelerate wear, so bump up inspection frequency if that sounds familiar. Quality parts, correct torque, and proper balance are the keys to keeping a BA Falcon smooth and happy.

Popular questions

Does a 2004 BA Falcon use CV joints or uni joints?
The tailshaft uses universal joints (and a centre support bearing on many sedans). BA sedans with independent rear suspension also have CV half-shafts from the differential to each rear wheel. Many utes with a live rear axle don’t have rear CV half-shafts but still rely on the tailshaft unis.

What are the signs my Falcon’s centre bearing or uni joints are failing?
Common giveaways include a shudder on take-off, a thump when shifting between drive and reverse, or a droning vibration that changes with speed. Underneath, look for rust-coloured dust at the uni caps, a cracked or sagging centre bearing rubber, or missing balance weights.

How often should driveshafts be serviced on a BA Falcon?
They’re largely maintenance-free but should be inspected at each service (about every 15,000 km/12 months). Cars that tow, are lowered, or see spirited driving benefit from more frequent checks. If anything’s worn or noisy, fix it early to avoid collateral damage.
