Parts for your 2004 Mazda Premacy-Universal joints

2004 Mazda Premacy universal joints — are they used or not?

For the 2004 Mazda Premacy sold in Australia and New Zealand, universal joints aren’t used in the driveline. The model is front‑wheel drive with a transverse transaxle, and the front drive shafts use constant velocity (CV) joints rather than universal joints. This is confirmed by the Mazda Premacy (CP) workshop manual and AU/NZ Mazda electronic parts catalogues, which list front drive shafts with inboard and outboard CV joints and no propeller shaft or driveline U‑joint service parts. The only universal joint you’ll typically find on these vehicles is the small cross‑type joint in the steering intermediate shaft, which isn’t the “driveshaft U‑joint” people usually mean.

• Mazda Premacy (CP, 1999–2005) workshop manual: Front drive uses CV joints, no propeller shaft on FWD models.
• Mazda Electronic Parts Catalogue (AU/NZ, 2004 Premacy): Lists CV joints/boots and front drive shafts, no driveline U‑joints.
• Market specs for AU/NZ Premacy: FWD configuration, AWD variants were not offered locally.

Why no universal joints? FWD packaging puts the gearbox and differential up front, so there’s no rear propeller shaft. More importantly, CV joints maintain constant rotational speed through large steering and suspension angles, which keeps vibration down and traction smooth — something a simple universal joint can’t do, as it introduces speed fluctuation at angle. That’s why Mazda engineered CV joints at both ends of each front shaft.

Note for import owners: Some Japan‑market Premacy/Family variants were available with 4WD, which adds a rear propeller shaft that uses universal joints. These are uncommon in AU/NZ. If you’re unsure, check your VIN build plate and look underneath for a rear diff and prop shaft.

What should be serviced instead? Keep an eye on the CV boots every 10,000–15,000 km or at each service. Torn boots fling grease and quickly destroy the joint. Clicking on full lock points to outer CV wear, shudder on take‑off can be inner CV or engine mounts. If the steering feels notchy or there’s play at the wheel, have the steering column U‑joint checked — it’s replaced as an assembly if worn.

• Does a 2004 Mazda Premacy have universal joints?
  Most AU/NZ 2004 Premacy models don’t have driveline universal joints. They’re FWD and use CV joints on the front drive shafts. There is a small U‑joint in the steering intermediate shaft, but that’s separate from the driveline. Japan‑market 4WD imports are the exception and will have prop‑shaft U‑joints.
• How do I tell a CV joint issue from a universal joint problem on a Premacy?
  On FWD Premacy models, clicking or knocking on full lock is a classic outer CV joint symptom, vibration under load can point to the inner CV or mounts. A failing steering U‑joint shows up as notchy, stiff, or inconsistent steering rather than driveline noises. If your car is an imported 4WD variant and you hear a clunk on take‑up or a droning vibration with vehicle speed, the prop‑shaft U‑joints may be in play.
• Is there any universal joint maintenance on this car?
  For FWD AU/NZ models, there’s no routine driveline U‑joint service because they’re not fitted. Inspect CV boots and replace joints/shafts if damaged. The steering U‑joint isn’t a greasable item, if there’s play or binding, it’s replaced.
