Parts for your 2017 Audi Q5-Universal joints

2017 Audi Q5 universal joints: what’s actually fitted and why it matters

For the 2017 Audi Q5 (FY series, MLB evo platform), traditional driveline universal joints (Hooke/Cardan type) are not used on the propeller shaft or half-shafts. Instead, Audi specifies constant velocity (CV) joints throughout the driveline. This is backed by technical references including Audi Self-Study Programmes covering the FY-series Q5 and quattro with ultra technology, the official Audi workshop manual (Elsa/ErWin) sections for the propeller shaft and rear final drive, and the Audi parts catalogue (ETKA), all of which list CV joint assemblies, boots and related hardware, with no serviceable U-joints in the driveline.

It’s worth noting there is a small universal joint in the steering intermediate shaft, but that’s a separate steering component, sealed-for-life, and not what most people mean when they ask about “driveline U-joints”.

Why no U-joints on the Q5’s driveline? Audi’s design choices prioritise refinement, efficiency and consistent torque delivery—especially with the FY Q5’s electronically controlled quattro ultra system on most models. CV joints keep rotational speed constant through an angle, which helps reduce vibration and shudder compared with traditional U-joints. They’re also quieter and better for NVH, and they come sealed and maintenance-free from the factory.

• Constant velocity through angles: smoother, more predictable torque transfer to the rear axle.
• Lower NVH: fewer driveline pulsations and less booming on long highway runs.
• Maintenance-free: sealed joints, no greasing intervals like old-school U-joints.
• Packaging and compatibility: suited to the Q5’s multi-link suspension geometry and AWD clutch control.

For owners thinking about servicing: because there are no greaseable U-joints to maintain, attention should go to the actual wear points Audi specifies—CV joint boots and clamps on the prop shaft and half-shafts, the prop shaft centre support bearing, and any rubber flex disc (if fitted on particular variants). During scheduled servicing or if driveline noises crop up, ask for an inspection of:

• CV boots for cracks, splits or grease sling.
• Propeller shaft play, centre bearing condition, and joint backlash.
• Transfer case and differential flanges for leaks and fastener torque.

Typical symptoms that need attention include clicking on take-off or tight turns (often CV-related), a rhythmic vibration that rises with road speed (could be prop shaft balance, centre bearing or a worn CV joint), or clunks when shifting from drive to reverse. Catching boot damage early can save a CV joint, once contaminated, the joint usually needs replacement. There’s no practical or recommended retrofit path to use traditional U-joints on this platform—doing so would increase NVH and complicate balancing and alignment.

Popular questions

Does a 2017 Audi Q5 have universal joints in the driveline?
No. The FY-series Q5 uses constant velocity joints on the propeller shaft and half-shafts. Audi’s workshop information and parts listings show CV joints and boots, not serviceable Hooke/Cardan U-joints. The only U-joint you’ll find is in the steering intermediate shaft, which is a different system and not a regular service item.

What should be serviced instead of U-joints on a 2017 Q5?
Focus on CV boots and joints, the prop shaft centre support bearing, and any flex disc components, plus checks for driveline fluid leaks. If there’s clicking on turns, vibration with road speed, or clunks on load changes, book an inspection—early attention to a split boot can prevent a costly joint replacement.

Can universal joints be retrofitted to the Q5?
It’s not recommended. The Q5’s driveline, including quattro ultra control, is engineered around CV joints. Swapping to traditional U-joints would introduce speed fluctuations, extra NVH, and balancing headaches, and it won’t offer any real-world advantages for this platform.
