Parts for your 2008 Mazda Premacy-Cv boots

2008 Mazda Premacy CV boots — what they do and how to look after them

CV boots are absolutely used on the 2008 Mazda Premacy (Mazda5). Mazda’s workshop literature for the CR-platform Mazda5 (2005–2010) and the OEM parts catalogue both specify inner and outer constant velocity (CV) joint boots on the front drive shafts. The front axle design uses a Rzeppa-type outer CV joint and a tripod-type inner joint, each protected by a flexible rubber boot filled with CV grease. So yes — this model is fitted with CV boots from factory.

On this Premacy, the boots keep specialised moly CV grease in and water, sand, and road grime out, letting the joints articulate smoothly through steering and suspension travel. When the boots stay intact, the joints last for ages, when a boot splits, grease is flung out, contaminants get in, and the joint can start clicking on turns or vibrating under load.

As part of routine servicing, it’s smart to give the CV boots a proper look every 10,000–15,000 kilometres or at each service interval. A quick check under the vehicle and behind the front wheels for sling marks (grease sprayed around the inner rim, strut or undertray) is a dead giveaway. Flex the boot pleats by hand to spot fine cracks, and check both clamps are snug with no weeping.

• Replace the boot immediately if there’s a tear, loose clamp, or significant cracking.
• If the joint is already noisy or rough, go for a complete shaft or joint replacement rather than a boot-only fix.
• Use quality OEM-spec boots, stainless clamps, and the correct molybdenum CV grease, clean out all old grease and grit.

Outer boot jobs typically take about 1–2 hours per side for a workshop. Universal stretch boots can be a stopgap, but on a Premacy a proper boot kit with the right profile and clamps is the tidy, longer-lasting solution. Coastal air, gravel roads, and big temperature swings across Australia and New Zealand can age rubber faster, so Premacy owners in those conditions should be extra vigilant.

Keeping the CV boots in good nick protects the joints, avoids roadside dramas, and saves a packet compared with replacing complete driveshafts later on.

Popular questions

How often should CV boots be checked on a 2008 Mazda Premacy?
They should be inspected at every regular service or roughly every 10,000–15,000 kilometres. If the vehicle sees lots of gravel, coastal driving, or frequent full-lock parking manoeuvres, a quick look between services is wise. Any sign of grease spray or cracking means it’s time to act.

Can the CV boot be replaced without removing the driveshaft?
For some outer boots, a split or stretch-boot tool lets a tech replace the boot without fully removing the shaft. However, the cleanest, most durable repair on a Premacy is usually done with the driveshaft out, allowing a thorough clean and repack with fresh moly grease.

What grease and clamps should be used for Premacy CV boots?
Use high‑molybdenum disulphide CV joint grease supplied in a proper boot kit or OEM-equivalent pack. Fit stainless or OEM ear-type clamps with the correct crimping tool to ensure even tension and no leaks. Avoid generic worm-drive hose clamps on the small end, they can cause imbalance or cut into the boot.
