Parts for your 2015 Audi Q5-Thrust bearing

2015 Audi Q5 thrust-bearing: what it does and how to look after it

Based on Audi technical literature (including Self-Study Programmes for the EA888 2.0 TFSI, 3.0 TFSI and 3.0 TDI engines) and standard parts catalogues used by Audi dealers, the 2015 Audi Q5 does use a crankshaft thrust-bearing. It’s integrated into the centre main bearing assembly (thrust faces/washers) to control crankshaft end-float. Similar axial-thrust elements are also present within the vehicle’s automatic transmissions per ZF and Audi gearbox technical descriptions. So “thrust-bearing” is very much a relevant component on a 2015 Q5.

On the Q5’s petrol and diesel engines, the thrust-bearing’s job is to keep the crankshaft from walking forwards and backwards under axial loads — think converter/clutch engagement, serpentine belt pull, and the push/pull forces during gearchanges. By controlling end-float, it protects main bearings, the crank webs, timing gear, and the transmission interface. If it goes out of spec, the engine can develop odd noises, shudder on take-up, or even damage the crank and block saddles.

While it’s critical, the thrust-bearing isn’t a routine “service item” like a filter. It’s inspected or replaced when the bottom end is apart, or if there are symptoms of excessive end-float. A switched-on workshop can check crank end-play with the engine in-car using a dial indicator during major servicing if there’s any suspicion.

• Common signs to watch: a rhythmic metallic rub at idle with the converter/clutch loaded, noticeable crank pulley fore–aft movement, erratic idle when shifting from Neutral to Drive, or unexplained wear swarf in the oil.
• Good practices: keep engine oil changes on time with the correct VW/Audi spec oil, address harsh shift complaints early (Tiptronic/S tronic updates), and avoid riding the drivetrain against a load (e.g., holding on hills with throttle rather than the brake).

If replacement is needed, it’s typically done during an engine-out or sump-off bottom-end job. The workshop will measure end-float against Audi spec, inspect the centre main bearing and crank thrust faces, and replace bearings as a set if required. It’s smart to pair this with other “while you’re there” items — rear main seal, sump reseal, oil pickup clean, and a fresh fill with the correct oil. With quality parts and proper clearances, a Q5’s thrust-bearing should last the life of the engine under normal Aussie and Kiwi driving.

Does a 2015 Audi Q5 actually have a thrust-bearing?

Yes. Audi engine manuals for the EA888 2.0 TFSI, 3.0 TFSI and 3.0 TDI specify thrust-bearing surfaces at the centre main to control crankshaft end-float. Transmission assemblies also use axial thrust elements.

What symptoms point to a worn thrust-bearing on a Q5?

Look for a scraping or rubbing noise at idle when selecting Drive, visible fore–aft crank pulley movement, harsh take-up, or excessive end-float on measurement. Metal flakes in oil can also be a clue.

Is thrust-bearing replacement part of normal servicing?

No. It’s inspected when diagnosing end-float issues or when the engine bottom end is opened. Replacement is done with the sump off or engine out, and is usually paired with related seals and bearings.
