Parts for your 2016 Ford Falcon-Universal joints

2016 Ford Falcon (FG X) universal joints — what they do and how to look after them

Based on Ford’s FG X Falcon Workshop Manual (Driveline: Propeller Shaft), the 2016 Falcon runs a two‑piece tailshaft with a centre bearing. It uses a constant velocity/flex coupling at the transmission on many variants and a universal joint (uni joint) at the differential end, some trims may have a uni at both ends. This layout is also reflected in Ford Australia parts catalogues for FG/FG X and in Australian driveline catalogues from Hardy Spicer/Spicer that list serviceable uni joints for FG-series Falcons. So yes — universal joints are absolutely relevant on a 2016 Ford Falcon.

The uni joint’s job is to let the tailshaft transmit torque while the rear suspension moves and the angles change. Without it, the tailshaft would bind, causing vibration, harshness, and potential damage to the gearbox output or diff pinion. On the road, a healthy uni keeps things smooth under load, whether it’s an XR6 commuter or a workhorse carrying a boot full of gear.

As part of regular servicing, it pays to give the Falcon’s uni joints a once-over. Most are sealed-for-life, but some replacements include grease nipples. A quick inspection every 10,000–20,000 km (or at each service) can save a tailshaft drama later. Look for cracked or missing seals, reddish dust around the caps, flung grease, or any free play. Rotate the shaft by hand with the car safely supported, any notchiness or slack is a red flag.

Tell‑tale symptoms of a tired uni joint include a clunk on take‑off or shifting from reverse to drive, a cyclical vibration at highway speeds, or a chirp/squeak at low speeds that changes with road speed. Because the Falcon’s tailshaft also has a centre bearing and often a CV/flex coupling up front, those parts should be checked at the same time — a vibration can come from any of them.

• When replacement’s due, mark the yokes for phasing, follow the workshop manual torque specs, and fit new circlips.
• If the joint is staked or the yoke is worn, a complete tailshaft end or assembly may be the right fix.
• Aftermarket greaseable joints should be lubed with a quality NLGI #2 chassis/driveline grease during services, especially if the car tows or sees rough roads.

A properly maintained uni joint keeps the FG X tailshaft balanced, quiet and safe — exactly what’s wanted for long Aussie and Kiwi stretches.

Popular questions about 2016 Ford Falcon universal joints

Does a 2016 Falcon use uni joints or only CV couplings?
The FG X typically uses a two‑piece tailshaft with a centre bearing, a CV/flex coupling at the transmission end on many models, and a universal joint at the differential end. Some variants may have an additional uni. Checking the tailshaft assembly number against the Ford parts catalogue will confirm the exact setup.

What noises point to a failing uni joint?
Common giveaways are a dull clunk when selecting drive or taking off, a rhythmic vibration between 80–110 km/h, and a light squeak at low speeds that speeds up with the car. Any of these warrant an inspection of the uni, centre bearing and front coupling together.

Can a worn uni joint damage other components?
Yes. Excess play causes vibration that can hammer the centre bearing, flog out the diff pinion bearing, and stress the transmission output. If there’s play or roughness, replace the joint promptly and recheck driveline angles and balance.
