Parts for your 2020 Audi Q5-Universal joints

Are universal joints used on the 2020 Audi Q5?

Short answer: for the driveline, no. The 2020 Audi Q5 (type FY, MLB evo platform) doesn’t use traditional cross-type universal joints (U‑joints) on its propeller shaft or axle shafts. Audi’s factory workshop literature (ElsaWin) for the FY Q5, the Audi ETKA parts catalogue (groups 38, 40–41), and Audi Self‑Study Programme material for the Q5/MLB evo driveline specify constant velocity (CV) joints at the propeller shaft and both front and rear drive shafts, with the prop shaft typically serviced as a complete unit that includes CV joints and a centre support bearing. Some variants also use a rubber flex coupling (giubo). That combination delivers the smoothness and durability Audi targets for Quattro models without resorting to serviceable U‑joints.

Why Audi doesn’t use U‑joints here comes down to refinement and geometry. CV joints maintain constant angular velocity through larger operating angles, which keeps vibration and shudder at bay under load and during steering or suspension movement. That suits the Q5’s independent suspension and the Quattro system’s torque delivery, and helps meet tight NVH targets. The trade-off is that these joints are sealed-for-life and, if worn, the shaft or joint is usually replaced rather than rebuilt in the traditional U‑joint way.

If someone’s chasing “universal joint” issues on a 2020 Q5, they’re almost always looking at CV joint or prop shaft support concerns instead. During servicing, a technician will typically:

• Inspect all CV boots for splits, grease sling, or clamps working loose.
• Check the propeller shaft’s centre support bearing and rubber mount for cracking or excess play.
• Look over the flex disc (if fitted) for perishing and bolt torque.
• Feel for axial/radial play at prop shaft CV joints and confirm balance weights are intact.
• Road-test for tell-tales like a driveline thrum on acceleration, a click on full lock, or a shudder at motorway speeds.

Note: the steering intermediate shaft does use a small cardan joint, but that’s a separate steering component and not the “universal joint” most people mean when talking about the Q5’s driveline.

Popular questions about 2020 Audi Q5 universal joints

Does the 2020 Audi Q5 have universal joints?
Not in the driveline. The FY Q5 uses CV joints on the propeller shaft and both axle shafts, with a centre support bearing and, on some versions, a flex disc. There isn’t a serviceable cross-type U‑joint on the prop shaft like you’d find on many utes or older rear‑drive setups.

What should be checked or serviced instead of U‑joints on a 2020 Q5?
Focus on CV boots and joints, the prop shaft centre bearing, and any flex disc. Look for grease leaks, torn boots, play at the joints, cracked rubber, and vibrations under load. If wear is found, the affected joint or the complete shaft assembly is typically replaced.

Can U‑joints be retrofitted to a Q5 driveshaft?
That’s not recommended. The Q5’s shaft design, balance, and NVH tuning rely on CV joints. Swapping to U‑joints would compromise refinement, alignment, and durability, and would likely create vibration issues.
