Parts for your 1999 Mazda Premacy-Universal joints

1999 Mazda Premacy universal joints: are they used?

Short answer: on most 1999 Mazda Premacy models found in Australia and New Zealand (front‑wheel drive), universal joints aren’t fitted. Mazda specified constant velocity (CV) joints on the front drive shafts, not U‑joints. This comes straight from Mazda’s CP‑series Premacy workshop material (Driveline/Axle sections) and the Mazda Electronic Parts Catalogue for 1999 VIN ranges, which show front half‑shafts with CV joints only. Universal joints do appear on the propeller shaft of some Japan‑market all‑wheel drive variants, but those aren’t the common ANZ deliveries.

Why no universal joints on the usual FWD Premacy? A universal joint creates a cyclic speed variation when operating at an angle, which can introduce vibration and shudder. A front‑drive people‑mover regularly runs large steering angles and needs smooth, constant shaft speed to keep torque delivery and NVH in check. That’s exactly what CV joints do: they maintain constant angular velocity across the joint, giving better steering feel and less vibration, plus compact packaging behind the hubs. That’s why Mazda (like most makers) chose CVs for the Premacy’s front drive shafts.

If someone is running an imported AWD Premacy from the same era, that model uses a rear propeller shaft with universal joints. In that case, U‑joints become a service item: check for free play, roughness, or rust bleed at the bearing caps, and listen for clunks or a rhythmic vibration on throttle. But for the mainstream FWD 1999 Premacy, there are no universal joints to replace or maintain.

• What to inspect instead on FWD models: CV boots for splits or grease fling, clicking on full lock (outer CV wear), inner CV vibration on acceleration, and gearbox oil leaks at the shaft seals.
• If a boot is torn, replace it promptly or the joint will wear fast, if a joint clicks, a quality replacement shaft or joint kit is the fix.

Technical basis: Mazda Premacy (CP) factory workshop manual Driveline/Axle sections specify CV‑jointed front half‑shafts, the Mazda EPC lists propeller shaft assemblies with U‑joints only on AWD variants. This aligns with standard driveline engineering guidance that reserves U‑joints for relatively straight prop shafts and uses CV joints where large operating angles and smooth torque transmission are needed (front‑drive applications).

Popular questions

Does a 1999 Mazda Premacy have universal joints?
For the typical ANZ‑market front‑wheel drive Premacy, no—there are CV joints on the front drive shafts and no U‑joints fitted. Some Japan‑market AWD versions do use universal joints on the rear prop shaft, but those are the exception here.

I’m hearing a clunk or vibration—could it be a U‑joint on my Premacy?
On a FWD Premacy, it’s unlikely because there’s no prop shaft U‑joint. Check the front CV joints (listen for clicking on full lock), engine and transmission mounts, lower control arm bushes, and wheel bearings. If yours is an AWD import, then also inspect the prop shaft U‑joints for play or binding.

Can the Premacy’s CV joints be serviced individually?
Yes. Boots can be replaced if caught early, worn joints can be swapped as a joint kit or as a complete driveshaft. Use the correct grease, new clamps, and torque the hub nut to spec to avoid premature wear or bearing issues.
