Parts for your 2015 Ford Falcon-Driveshafts

2015 Ford Falcon driveshafts

Driveshafts are absolutely relevant to the 2015 Ford Falcon (FG X). Technical sources including the Ford FG X Falcon Workshop Manual (Driveline/Driveshaft sections), Ford Australia’s FG X Specification Guide, and long-standing service literature for BA–FG series confirm the model’s rear-wheel-drive layout uses a tailshaft (propeller shaft) from the transmission to the rear differential, and—on FG X sedans with independent rear suspension—two rear CV half‑shafts (commonly called driveshafts) from the diff to each wheel hub. Ute variants still use a tailshaft and axle shafts within the live rear axle. So, whether sedan or ute, the Falcon employs driveshaft hardware as core driveline components.

The purpose of these parts is straightforward: transmit torque smoothly from the gearbox to the rear wheels while allowing movement from suspension travel and changes in driveline angle. The tailshaft typically runs as a two‑piece unit with a centre support bearing to control vibration and NVH. At the rear, the sedan’s CV half‑shafts handle articulation as the independent rear suspension works, using inner and outer CV joints protected by rubber boots packed with grease.

As part of regular servicing, driveshafts deserve a quick once‑over. Sensible intervals are at every service or 15,000 km, and more often for vehicles that tow, are lowered, or cop rough roads.

• Inspect CV boots (inner and outer) for splits, perishing, or grease fling. Any damage means the joint risks rapid wear—replace the boot or the complete shaft as required.
• Check for play or clicking in the rear CV joints when rotating the wheel by hand, on road, listen for clunks on take‑up or a rhythmic knock under load.
• On the tailshaft, check the centre support bearing for cracking or sagging, and feel for vibration or droning at highway speeds. Inspect universal/CV joints for free play and dried or leaking seals.
• Confirm tailshaft and flange fasteners are correctly torqued, look for rust trails or fretting marks around joints.

Replacement is straightforward with the right kit: use quality OEM or reputable aftermarket shafts, renew single‑use flange bolts and axle nuts where specified, and torque everything to workshop‑manual spec. After fitting, inspect diff seals, road‑test for vibration, and recheck fasteners. No fixed replacement interval exists—condition rules. For high‑output XR variants, more frequent checks are smart insurance.

Popular questions

Does a 2015 FG X Falcon have CV joints?
Yes. FG X sedans with independent rear suspension use CV joints on both rear half‑shafts, and many tailshafts use a CV‑type joint at one end plus a centre support bearing. Ute variants still have a tailshaft, their rear axle setup differs, but driveline joints still manage angle changes and torque.

What are the common signs a Falcon driveshaft is worn?
Grease spray around the rear hubs or diff, split CV boots, a click or knock under load, a clunk on take‑up, or a steady vibration/shudder between 60–100 km/h are all classic signs. A tired centre bearing can add a droning noise and harshness. Any of these warrant inspection before they cascade into bigger repairs.

Can the tailshaft be rebalanced or does it need replacing?
A competent driveline shop can often rebalance a tailshaft and replace the centre bearing or joints. If the tube is dented, badly out of true, or joints are flogged, a quality exchange or new unit is usually the better long‑term fix.
