Parts for your 2005 Ford Falcon-Cv joint

2005 Ford Falcon CV-joint — what it does and when to sort it

Based on technical references — including the Ford BA/BF Falcon Workshop Manual (Ford Australia, 2002–2008), Gregory’s Ford Falcon BA–BF 2002–2008 Service and Repair Manual, and local parts catalogues for BA/BF driveline components — a 2005 Ford Falcon sedan and XR models use constant velocity (CV) joints on the rear half-shafts as part of the Control Blade independent rear suspension. The same sources note the 2005 Falcon wagon and ute retained a live rear axle, so those variants don’t use rear CV-joints.

For 2005 Falcon sedans, the cv-joint’s job is to let the rear wheels move up and down with the suspension while still transferring drive smoothly from the diff. Each rear axle typically runs an inner tripod-style CV and an outer Rzeppa-style CV. When they’re healthy, you get quiet, vibration-free drive and tidy grip, even over rough roads.

Servicing-wise, the big ticket is keeping the CV boots intact. Those rubber boots hold special moly grease and keep out grit. A split boot lets grease fling out and dirt work in, chewing the joint quickly. During routine servicing, a quick look for torn boots, grease spray on the inner guards, or dampness around the clamps goes a long way. If a boot’s split, replacing just the boot and repacking with the right CV grease can save the joint if it’s caught early.

Signs a Falcon’s rear cv-joint is on the way out include:

• Clicking or clacking on acceleration from low speed or on tight turns
• Shudder or vibration under load at motorway speeds
• Grease splatter near the inner wheel or diff area

If there’s noise or play, replacing the complete rear axle shaft assembly is often the most reliable fix. Many quality aftermarket shafts come pre-greased and booted, making the job quicker and tidy. It’s smart to replace the axle nut, check the wheel bearing, and inspect the diff output seals at the same time. No wheel alignment is usually needed, but a quick check of rear toe/camber is good practice on an IRS Falcon after any driveline work.

A couple of notes for owners: the Falcon is rear-wheel drive, so it doesn’t have front CVs like a front-drive hatch. And while CVs don’t have a set replacement interval, regular inspection during normal servicing — especially if the car tows, sees gravel roads, or lowered suspension — will keep the rear end quiet and reliable for years.

• Popular questions

Does a 2005 Ford Falcon have front cv-joints?
No. The 2005 Falcon is rear-wheel drive, so there are no front drive shafts or front CVs. On sedan and XR models, the CV-joints are on the rear half-shafts as part of the independent rear suspension.

How long do rear cv-joints last on a BA/BF Falcon?
With intact boots and clean grease, they can last well over 200,000 km. Harsh roads, torn boots, or lowered suspension can shorten that. Regular inspections and early boot replacement greatly extend service life.

Can just the CV boot be replaced, or is a full axle swap better?
If the joint isn’t noisy and there’s no excessive play, a new boot and fresh CV grease is fine. If there’s clicking, roughness, or metal flake in the old grease, a complete axle replacement is usually the smarter, longer-term fix.
