Parts for your 2014 Mazda Premacy-Universal joints

2014 Mazda Premacy universal-joints — are they used?

Short answer: the 2014 Mazda Premacy (Mazda5, CW series) doesn’t use universal-joints in its driveline. It’s a front‑wheel‑drive people mover with no propeller shaft, so there are no rear or centre universal-joints like you’d see on a ute or longitudinal rear‑drive setup. Mazda’s own workshop information for the CW platform specifies constant‑velocity (CV) joints on the front drive shafts (outer Rzeppa and inner tripod types) and lists no prop shaft assembly in the parts catalogue for 2014 Premacy models. That aligns with standard FWD practice described in chassis and drivetrain texts: CV joints are required at the steered front wheels to maintain constant angular velocity and smooth torque delivery at larger operating angles, where a single Cardan (universal) joint would create cyclic speed variation and vibration.

• Mazda 5/Premacy (CW) Workshop Manual – Drive Shaft System, Front Axle sections
• Mazda Electronic Parts Catalogue (EPC) – CW Premacy 2014, Front Axle/Driveline listings (no propeller shaft)
• Automotive chassis and drivetrain references (e.g., Bosch Automotive Handbook, SAE texts) contrasting CV joints vs universal joints for FWD

Why universal-joints aren’t used here: the Premacy’s transverse engine and transaxle send power straight to the front hubs via CV shafts. CV joints keep wheel speed and shaft speed matched even while steering and moving through suspension travel, giving better NVH and durability. A traditional universal joint would introduce speed fluctuation unless used in a carefully phased pair, and even then it’s not ideal for the high articulation angles needed at the front wheels.

Worth noting: there is a small universal joint in the steering intermediate shaft on most modern Mazdas, including the Premacy. That’s a steering component, not part of the driveline universal-joints category. It’s typically serviced by replacing the intermediate shaft assembly if there’s free play, corrosion, binding, or a clunk on steering input. As part of routine servicing, technicians usually check for any notchiness or looseness at the steering joint, and under the bonnet they’ll inspect the front CV boots for splits and fling-off grease. If a driver hears clicking on full lock or feels vibration on acceleration, that’s far more likely to be a worn CV joint or an inner joint issue than a universal joint on this model. Regular inspections every 10,000–15,000 kilometres, quick road tests, and keeping boots intact will keep the Premacy’s front end happy without chasing non-existent driveline universal-joints.

• Does a 2014 Mazda Premacy have driveline universal-joints?
  Not in the driveline. It’s FWD with CV shafts only. There’s no prop shaft, so no rear or centre universal-joints to replace. If you’re hearing clunks or vibrations, think CV joints, engine mounts, or wheel bearings first.
• What joints does it use instead of universal-joints?
  Front axles use an outer Rzeppa CV joint and an inner tripod CV joint. These allow big steering angles and suspension movement while keeping torque delivery smooth. They’re protected by rubber boots that should be checked at each service.
• Are there any universal-joints on the car at all?
  Yes, in the steering intermediate shaft. That’s a small U‑joint assembly linking the column to the rack. If it develops play or corrosion you may feel notchiness or a clunk, the usual fix is replacing the intermediate shaft, not a driveline repair.
