Parts for your 2015 Ford Falcon-Cv joint

2015 Ford Falcon CV joint — what it does and when to replace

For the 2015 Ford Falcon FG X sedan, a CV joint is absolutely relevant. Ford’s FG X Workshop Manual (Section 205-02: Rear Drive Axle/Differential) and Ford service information confirm the sedan’s independent rear suspension uses left and right halfshafts with inboard and outboard constant velocity joints. Major parts catalogues widely used in Australia and New Zealand (e.g., Repco and Burson) list complete “rear CV shafts” for FG/FG X sedans, reinforcing fitment. By contrast, the 2015 Falcon Ute keeps a live rear axle, so it doesn’t run rear halfshafts or CV joints.

On the FG X sedan, the CV joints let the rear wheels travel up and down while transferring torque from the diff smoothly, even at changing angles. That smooth, constant velocity delivery cuts driveline vibration, keeps tyre contact consistent, and makes the car feel planted when pushing on. They’re packed with high-moly grease and sealed by flexible boots that keep grease in and grit out—when those boots fail, the joint’s life goes downhill fast.

As part of routine servicing, CV joints don’t need regular greasing (they’re sealed), but they do need regular eyes-on checks:

• Inspect CV boots for splits, perishing, or loose clamps, look for grease flung around the inner guards or suspension arms.
• Listen for clicking, clacking, or a rhythmic knock on take-off or during tight turns, feel for shudder under acceleration that eases off when coasting.
• Check for play at the hub with the wheel off the ground, and note any vibration at 80–110 km/h that changes under load.

If a boot is damaged but the joint’s quiet and play-free, a new boot and fresh grease can save the day. Once contamination has set in, though, replacing the affected joint—or more commonly, the complete CV shaft—tends to be the smarter, time-saving fix. When fitting a shaft, torque all fasteners to the workshop spec, ensure the circlips locate correctly, and road test for noise. It’s also a good time to check diff bushes and rear wheel bearings, as worn mounts can mimic CV symptoms.

High-kilometre cars, vehicles lowered on stiffer springs, or Falcons that tow regularly can see earlier CV wear due to steeper operating angles and extra load. Many owners opt to replace shafts in pairs once past the 150,000–200,000 km mark if symptoms are creeping in. Keep the boots healthy and the CVs usually go the distance.

• Does a 2015 Ford Falcon have CV joints?
  The 2015 FG X sedan does—there are CV joints on each rear halfshaft (inboard and outboard). The 2015 Falcon Ute uses a live rear axle, so it doesn’t have rear CV joints.
• How long do rear CV joints last on an FG X?
  With intact boots, many last well beyond 150,000 km. Heavy towing, lowered suspension, or perished boots can shorten their lifespan. Regular boot inspections help them last longer.
• Can a worn rear CV cause shudder on acceleration?
  Yes—especially a loaded-up vibration that eases when coasting. Also check the tailshaft centre bearing, diff bushes, and rear wheel bearings, as they can cause similar symptoms.
