Parts for your 2005 Mazda Premacy-Universal joints

2005 Mazda Premacy universal joints – relevant or not?

For the 2005 Mazda Premacy as sold in Australia and New Zealand (front‑wheel drive), universal joints aren’t used in the driveline. The vehicle’s front drive shafts use constant velocity (CV) joints—outer Rzeppa and inner tripod/DOJ types—rather than Hooke‑type universal joints. This layout is shown in the Mazda workshop manual for the Premacy/CR series (front drive shaft section) and mirrored in typical aftermarket guides for the Mazda 5/Premacy platform, which describe CV joints at both ends of each half‑shaft. An OEM electronic parts catalogue for FWD models also omits any rear propeller shaft assembly (where U‑joints would normally live) but does list an intermediate steering shaft with a small universal joint for the column.

Why no universal joints? It’s the drivetrain architecture. A transverse engine with FWD needs joints that can transmit torque smoothly at large steering and suspension angles, CV joints maintain constant rotational speed through big angles, while a classic U‑joint doesn’t—it introduces speed fluctuation and vibration unless paired and phased on a long prop shaft. Because FWD Premacy models don’t have a rear propeller shaft, there’s simply nowhere a serviceable driveline U‑joint would go. That’s why routine servicing focuses on CV boots and joints rather than greasing or replacing U‑joints.

There is one place you might hear “universal joint” on this car: the steering column. The intermediate shaft uses a small U‑joint to link the column to the rack. It’s a different component from a driveline U‑joint and is only inspected if there’s steering play, stiffness, or a notchiness around centre.

• Technical basis: Mazda Premacy (CR) workshop manual – Front Drive Shaft section specifies CV joints, not U‑joints.
• Parts cataloguing: FWD models show no rear propeller shaft, steering intermediate shaft includes a small U‑joint.
• General FWD service literature (Mazda 5/Mazda 3 era): CV joints are the service items, U‑joints apply to RWD/4WD prop shafts.

If you have a grey‑import AWD/JDM Premacy, it may have a rear propeller shaft that uses U‑joints or CV couplings, those vehicles weren’t commonly sold new in AU/NZ. In that case, inspection would include play at the shaft ends, boot/seal condition, and any clunks under load.

Popular questions

Does a 2005 Mazda Premacy have universal joints in the drivetrain?
FWD models sold in Australia and New Zealand do not. They use CV joints on the front drive shafts. A small U‑joint exists on the steering intermediate shaft, which is unrelated to the drivetrain. Only some AWD/JDM variants have a rear prop shaft where U‑joints or CV couplings may be used.

If a parts listing says “universal joint” for a Premacy, what should be ordered instead?
For FWD models, you’ll typically be chasing CV joints, CV boots, or complete drive shafts. If the issue is in the steering, the correct part is the intermediate steering shaft or its U‑joint, not a driveline U‑joint.

What symptoms point to CV joints rather than a universal joint on this car?
Clicking on full lock, split rubber boots with grease fling, or vibration on acceleration usually indicates CV joint or shaft issues. Clunks on take‑off in a FWD Premacy are far more likely CV/engine mount related than a driveline U‑joint, because there isn’t one fitted.
