Parts for your 2020 Mazda Cx-5-Universal joints

2020 Mazda CX-5 universal-joints — are they used?

For the 2020 Mazda CX-5, traditional cross-type universal joints (U-joints) are not used as separate, serviceable components. Technical references from Mazda’s workshop manual for the KF-series (Driveline/Axle sections covering Front Drive Shaft and Propeller Shaft) specify constant velocity (CV) joints on the front halfshafts, and a propeller shaft assembly on AWD models that employs CV-type joints with a centre support bearing. Mazda’s electronic parts catalogue for the 2020 CX-5 lists the propeller shaft as a complete assembly without a separate U-joint kit, reinforcing that there are no greaseable or replaceable U-joints on this platform.

Why no U-joints? The CX-5’s transverse engine layout and independent suspension rely on CV joints to maintain constant rotational speed through larger operating angles, which keeps vibration and noise low. On AWD versions, the long prop shaft to the rear differential also uses CV-type couplings for smoothness and packaging. It’s a modern crossover approach: sealed CV joints and assemblies instead of serviceable U-joints.

• Front-wheel-drive models: No propeller shaft at all, only front CV axles.
• AWD models: Propeller shaft with CV-type joints and centre bearing, no separate U-joints.
• Parts support: Mazda catalogues CV axles and complete prop shafts, no standalone U-joint listings.

What should owners do at service time? Rather than chasing U-joints, technicians should inspect CV boots for splits or grease fling, check for clicking on full lock (outer CV joint wear), and feel for vibration under load or at highway speeds that may point to a worn prop shaft centre bearing or inner CV joint. Any joint play, torn boots, or contaminated grease usually calls for replacement of the affected CV axle or the complete propeller shaft assembly, as individual joints are typically non-serviceable on this model. Fresh driveline fluids in the transfer case and rear diff (for AWD) on schedule will also help keep the system happy.

If a customer reports clunks, shudders, or a droning sound that rises with road speed, a road test and underbody inspection for CV boot damage, loose heat shields, or a tired centre bearing is the go. But there’s no routine greasing of U-joints on a 2020 CX-5—because they’re simply not fitted.

Popular questions about 2020 Mazda CX-5 universal-joints

Does a 2020 Mazda CX-5 have universal joints?
No. The CX-5 uses constant velocity (CV) joints on the front driveshafts, and AWD models use a propeller shaft with CV-type joints and a centre bearing. There are no separate, greaseable U-joints listed by Mazda for this vehicle.

What should be serviced instead of U-joints on a CX-5?
Focus on CV boots and joints, the AWD propeller shaft assembly and centre bearing (if equipped), and the transfer case and rear differential fluids. Damaged boots, clicking on turns, or vibrations under load point to CV or prop shaft issues, not U-joints.

How can drivers spot driveline issues on a 2020 CX-5?
Listen for clicking when turning (outer CV wear), feel for vibration during acceleration or at motorway speeds (possible inner CV or centre bearing), and watch for grease spray around a torn boot. These symptoms warrant prompt inspection and likely replacement of the affected axle or the complete prop shaft assembly.
