Parts for your 2014 Audi Q5-Thrust bearing

2014 Audi Q5 thrust-bearing — what it is and how to look after it

Based on Audi factory workshop information (ELSA/erWin) for the 8R-series Q5, every 2014 Audi Q5 engine uses integrated crankshaft thrust bearings (thrust washers within the main bearing set) to control crankshaft end float. In models fitted with the 7‑speed S tronic (DL501) dual‑clutch gearbox, Audi Self‑Study Programme material on the 0B5/DL501 details a concentric slave cylinder with an integrated release bearing (commonly called a thrust bearing). Tiptronic (ZF 8HP) models don’t have a clutch release bearing, but the engine’s thrust bearings are still present. These mainstream technical sources confirm a thrust-bearing is indeed relevant to the 2014 Q5.

In this Q5, the thrust-bearing has two common contexts. First, inside the engine, thrust washers sit with the main bearings to keep the crankshaft from walking forwards and backwards under axial loads from the accessory drive, torque converter or clutch engagement. Keeping crank end float in check helps maintain oil film integrity, stable timing, and smooth gear engagement. Second, in S tronic models, the gearbox’s release (thrust) bearing transmits the axial load when the clutch is actuated, allowing smooth, quiet clutch operation.

It’s not a routine service item, but it deserves attention at the right moments. For S tronic vehicles, best practice is to replace the release bearing (it’s part of the concentric slave cylinder assembly) whenever the transmission is removed for clutch or mechatronics work. Use quality OEM-spec fluid and observe the scheduled S tronic service to help the clutch and bearing live a long life.

Engine thrust bearings are only inspected or replaced when the sump is off or during engine repair. If there’s unusual crank end float, metallic rubbing noises, or wear particles in the oil, a precise measurement with a dial gauge is warranted. Excess end float can be caused by sustained axial loads (e.g., aggressive clutch habits on manual/DCT variants) or lubrication issues, correcting the root cause is as important as fitting new bearings.

• Typical warning signs: whirring or growling when engaging gear (S tronic), clutch chatter, difficulty selecting gears, or measurable crank end float.
• Good habits: avoid riding the clutch, service S tronic fluid on time, and fix any oil pressure or contamination issues promptly.
• Parts tip: choose OEM or high‑quality equivalents, and renew associated seals/bolts when the gearbox or sump is off.

Looked after properly, the Q5’s thrust-bearing components stay quiet and dependable for the long haul across Kiwi and Aussie roads.

Popular questions

Does my 2014 Audi Q5 have a thrust-bearing if it’s a Tiptronic automatic?
Yes. While Tiptronic models don’t have a clutch release (thrust) bearing, the engine still uses thrust washers integrated into the main bearings to control crankshaft end float. These aren’t routine service items and are only checked during engine work.

When should the S tronic thrust/release bearing be replaced?
On S tronic models, replace the concentric slave cylinder and integrated release bearing whenever the gearbox is out for clutch service or major transmission work. It’s cost‑effective insurance against future noise or engagement issues.

What symptoms point to a worn thrust-bearing?
For S tronic: growling or whirring with clutch engagement, rough take‑off, or gear selection issues. For engine thrust bearings: noticeable crankshaft end float, metallic rub noises at the front of the engine, or concerning debris in the oil. Any of these warrant professional diagnosis.
