Front Axle Shafts For Audi Q5, A6, A7 & A8 Quattro 2.0L 3.0L, 2009-2018

Front Axle Shafts for the Q5, A6, A7, and A8 Quattro

This is a pair of front axle shafts built for the Audi Q5 8R (2009-2017), A6 4G/C7 (2012-2018), A7 4G Sportback (2011-2018), and A8 4H/D4 (2011-2018), all with Quattro all-wheel drive in 2.0L or 3.0L form, cross-referenced to a wide range of OE numbers including 4G0407271F and 8R0407271. If you're feeling a vibration that gets worse with speed, hearing a clicking noise when turning, or noticing a clunk when accelerating from a stop, a worn front axle shaft is a common cause on these Quattro models.

Why These Quattro Models Share an Axle Shaft

The Q5, A6, A7, and A8 from this era were built on closely related versions of Audi's MLB platform architecture, which is why a single pair of front axle shafts covers a Quattro crossover, two different sedan body styles, and Audi's flagship A8 despite their different sizes and price points. Because all four use a similar longitudinal-engine, all-wheel-drive layout, the front driveline components that connect the transmission to the front wheels were engineered to common dimensions across these models even though the vehicles themselves look and feel quite different to drive. That kind of shared driveline engineering across a manufacturer's larger platform family is common in the industry, which is part of why cross-referencing OE numbers rather than relying on the model name alone is worth doing when ordering.

Compatibility

Fits the Audi Q5 8R (2009-2017), A6 4G/C7 (2012-2018), A7 4G Sportback (2011-2018), and A8 4H/D4 (2011-2018), all in 2.0L or 3.0L Quattro configuration. Because these model lines were also offered with front-wheel-drive variants and other engine options in some markets and years that use different axle shafts, it's worth confirming your specific vehicle's drivetrain against the OE numbers above before ordering to guarantee an exact match.

Signs Your Axle Shaft Needs Replacing

A worn front axle shaft on these Quattro models typically shows up as a clicking or popping noise when turning at low speed, a vibration that intensifies as road speed increases, or a clunk felt through the cabin when accelerating hard from a stop. Because a torn CV boot at either end of the axle shaft is often what starts the failure by letting grease escape and dirt in, a visual check of both boots is worth doing any time these symptoms appear, even before assuming the shaft itself needs replacing.

Why Owners Replace the Complete Axle Shaft

Once the constant-velocity joints at either end of an axle shaft have worn enough to cause clicking or vibration, servicing the joints individually isn't practical on most of these Quattro platforms, which is why replacing the complete axle shaft assembly is the standard repair rather than attempting to rebuild a single joint. Starting with a new shaft means new joints and boots throughout, which avoids the risk of a second failure shortly after a partial repair on a component that's constantly flexing and spinning as the wheel turns and the suspension moves.

Installation Notes

Replacing a front axle shaft means removing the wheel, separating the shaft from the wheel hub and the transmission or differential, and installing the new shaft in reverse order with a fresh axle nut torqued to specification. Because the axle nut on these Quattro models is typically torqued well beyond what most hand tools can manage, having the vehicle's weight on its wheels (rather than on a jack) when doing the final torque is worth planning for ahead of time.
