Parts for your 2020 Mazda 3-Universal joints

2020 Mazda 3 Universal Joints

Technical references including the Mazda 3 (BP) Workshop Manual and Mazda’s electronic parts catalogue show the 2020 Mazda 3 uses constant velocity (CV) joints on its front drive shafts, and no propeller shaft or driveline U‑joints on Australian and New Zealand models (front‑wheel drive). However, the steering system does incorporate an intermediate steering shaft with a universal joint. So, universal joints are relevant to the 2020 Mazda 3 in the steering column, not the driveline.

On the 2020 Mazda 3, the universal joint in the steering intermediate shaft lets the column change angle and still turn smoothly, connecting the steering wheel to the rack. It’s a compact cardan joint that copes with body and suspension movement without introducing slop or notchiness. Mazda’s workshop procedures describe it as a non‑serviceable component: it isn’t designed to be greased and is replaced as an assembly if wear or corrosion sets in.

As part of regular servicing, it’s smart to have a technician quickly check for play or binding in the steering shaft, especially if the owner reports clunks over bumps, a notchy feel when turning, heavier‑than‑normal steering, or a steering wheel that doesn’t return to centre cleanly. Those symptoms can point to a tired universal joint. Vehicles used near the coast or on unsealed roads can see the joint pick up surface rust sooner, so periodic inspection is worthwhile.

Replacement is straightforward for a trained tech: battery disconnected (to protect the airbag system), steering locked in the straight‑ahead, intermediate shaft marked for alignment, then the old joint is removed and a new genuine or high‑quality aftermarket unit installed. Bolts are torqued to spec and the steering wheel alignment verified. There’s no set replacement interval—it’s condition‑based. Many last the life of the car, but if any free play, stiffness, or rust is found, replacing early avoids extra wear on the steering rack and keeps the on‑centre feel crisp.

Tips owners will appreciate:

• Act on any clunk, bind, or stiffness promptly—steering feel is a safety item.
• No grease nipples here, if it’s rough or loose, it needs replacing.
• After replacement, request a quick road test to confirm smooth, even steering effort.

Popular questions about 2020 Mazda 3 universal joints

Does a 2020 Mazda 3 have universal joints?
Yes—there’s a universal joint in the steering intermediate shaft. The driveline uses CV joints up front and, on AU/NZ models, there’s no rear prop shaft or driveline U‑joints. That’s per the BP‑series workshop manual and parts listings.

How long does the steering universal joint last?
Often the life of the car. That said, exposure to moisture and grit can age it faster. Have it checked during routine services or if there’s any notchiness or clunk. It’s replaced as an assembly if worn.

Can the universal joint be lubricated or adjusted?
No. It’s a sealed, non‑serviceable part with no grease points. If it’s stiff or loose, replacement is the proper fix, followed by checking steering wheel centring and fastener torque.
