Parts for your 2009 Mazda Premacy-Cv boots

2009 Mazda Premacy CV-boots: what they do and when to replace them

Based on the Mazda Workshop Manual for the CR-chassis Premacy/Mazda5 (Drive Shaft section) and the Mazda Electronic Parts Catalogue listings for front drive shafts, the 2009 Mazda Premacy is fitted with inner and outer constant velocity (CV) joints that are protected by CV boots. These sources, along with general service data used in ANZ workshops (e.g., Autodata/Haynes procedures for Mazda5 CR), confirm CV boots are relevant and used on this vehicle.

On a 2009 Mazda Premacy, the CV boots are the flexible rubber or thermoplastic sleeves that seal grease around the CV joints on each front drive shaft. Their job is simple but crucial: keep the special moly grease in, and dust, water, and grit out. When a boot cracks or splits, the joint loses lubrication and rapidly wears, which can lead to clicking on turns and, eventually, a failed joint.

As part of routine servicing, it’s smart to check CV boots at every service interval. In Aussie and Kiwi conditions—heat, road grime, and the odd gravel run—boots can age faster, so a quick look during oil changes or tyre rotations is spot on. Look for grease flung around the inner wheel, struts, or undertray, plus any visible splits, perishing, or loose clamps.

If a boot is torn but the joint’s still quiet and smooth, a boot-only replacement is usually fine. That means cleaning the joint, packing fresh CV grease, and fitting a quality boot with proper stainless clamps (don’t use cable ties). If there’s clicking on full lock, roughness, or rust-coloured grease, it’s often more economical to replace the joint—or the complete driveshaft—rather than just the boot.

Good practice when replacing: use the correct type-specific boot (inner and outer differ), crimp clamps with the proper tool, and torque the axle nut to spec as outlined in the Mazda Workshop Manual. After reassembly, a wheel alignment check is a good idea, especially if the suspension has been disturbed.

• Typical inspection cadence: every service or 10,000–15,000 km.
• Watch for: grease spray, clicking on turns, torn or perished rubber, loose clamps.
• Most 2009 Premacy models in ANZ are front-wheel drive, so CV boots are on the front, rear hubs aren’t driven.

Popular questions

Does the 2009 Mazda Premacy have CV boots on the rear?
Most 2009 Premacy models sold in Australia and New Zealand are front-wheel drive, so there are no rear CV boots. They use non-driven rear hubs. If a rare 4WD variant is encountered (primarily JDM), rear drive shafts would also have CV boots.

How often should CV boots be inspected on a 2009 Mazda Premacy?
They should be checked at every routine service—about every 10,000–15,000 km or six months. It’s also worth inspecting before long road trips or after driving on gravel roads.

Can a split CV boot be replaced without changing the whole axle?
Yes, if the joint hasn’t run dry or started clicking. Replace the boot, clean the joint thoroughly, and repack with the correct grease. If the joint is noisy or gritty, a new joint or complete shaft is the better fix.
