Parts for your 2012 Audi Q5-Centre bearing

2012 Audi Q5 centre-bearing: purpose, servicing and replacement

Based on Audi’s factory literature and parts data (Audi ETKA parts catalogue for model 8R/Q5, the Audi workshop manual/ElsaWin section for the propeller shaft, and Audi Self‑Study Programme 424 on the Q5 drivetrain), the 2012 Audi Q5 quattro uses a two‑piece propeller shaft with a centre-support bearing (centre-bearing). Audi supplies the bearing as part of the complete prop shaft assembly. Front‑wheel‑drive variants (where sold) don’t have a propeller shaft and therefore don’t use a centre-bearing. Most AU/NZ‑delivered MY2012 Q5s are quattro, so the centre-bearing is relevant on these cars.

The centre-bearing’s job is simple but vital: it supports the middle of the two‑piece prop shaft, keeping everything aligned under load so torque gets from the transmission to the rear diff smoothly. The rubber-mounted carrier absorbs vibration and movement as the driveline twists, helping the Q5 feel calm at motorway speeds and tidy over bumps.

When the rubber perishes or the bearing wears, drivers often notice a thump on take‑off, a droning or buzz between roughly 40–80 km/h, or a shudder under light throttle. Left alone, a failed carrier can let the shaft go out of line, which can take out CV joints or flog out the mount holes.

• What to watch for:
  • Vibration or drumming through the floor at steady speeds.
  • Clunk on initial acceleration or when shifting from reverse to drive.
  • Visible cracks or separation in the rubber carrier, oily degradation from leaks.
• Service and replacement tips:
  • Inspect the carrier rubber and prop shaft play at regular services (every 15,000 km is a good habit).
  • Audi sells the prop shaft complete, reputable aftermarket carriers exist, but correct installation and shaft phasing are critical.
  • During replacement, mark the shaft sections before separation, support the exhaust and heat shields, and set the carrier bracket pre‑load/alignment as per the workshop manual to avoid new vibrations.
  • Check related items while you’re in there: centre CV joint boot condition, rear diff mount, and transmission mount.

For owners who tow, drive on corrugations, or see lots of city stop‑start, a quick under‑car look for rubber cracking each service can save a bigger bill later. If any doubt, a driveline specialist or Audi‑savvy workshop can confirm with the car on a hoist and a short road test.

Popular questions about the 2012 Audi Q5 centre-bearing

Does every 2012 Q5 have a centre-bearing?

Quattro models do, because they use a two‑piece propeller shaft to drive the rear wheels. Any front‑wheel‑drive Q5 (where offered) won’t have a prop shaft or a centre-bearing. Most AU/NZ cars from this year are quattro, so they’re fitted.

Do I have to replace the whole prop shaft to fix the centre-bearing?

Genuine Audi supply the centre-bearing as part of the complete prop shaft. Quality aftermarket carriers are available, but proper installation matters: the shaft must be kept in phase, the carrier aligned and pre‑loaded correctly, and the result checked for balance‑related vibrations. Many workshops still prefer the complete shaft for a faster, lower‑risk repair.

What does a failing centre-bearing feel like?

Common signs include a thump on take‑off, a low‑frequency drone at suburban speeds, and a floorpan buzz on light throttle. If the rubber carrier has visibly cracked or the shaft can be moved up/down by hand near the carrier, it’s time to sort it.
