Parts for your 2017 Nissan Serena-Thrust bearing

2017 Nissan Serena thrust-bearing — what’s actually fitted

Short answer: a clutch-style thrust-bearing (release/throw-out bearing) is not fitted to the 2017 Nissan Serena (C27). Technical references that support this are the Nissan Serena C27 Service Manual (TM–CVT section), which specifies an Xtronic CVT (Jatco RE0F10D/JF016E) with a torque converter rather than a manual clutch, and the Nissan FAST/parts catalogue for C27, which lists no clutch release bearing for this model. The MR20DD engine does have crankshaft thrust bearings integrated into the main bearing set (Engine Mechanical “EM” section), but these are internal to the engine and not a routine service item.

Why there’s no thrust-bearing to replace: on a manual gearbox, the driver’s clutch pedal works a release (thrust) bearing that contacts the pressure plate springs. The C27 Serena uses a torque converter CVT, so there’s no clutch pedal and no external release/thrust-bearing. Inside the CVT there are various roller/needle thrust bearings and thrust washers, but they live deep inside the transmission and aren’t serviced on their own, they’re addressed during a CVT overhaul if required.

What owners should do instead: if someone’s chasing a “thrust-bearing” noise on a Serena, they’re usually thinking of the classic manual-box whirring or squeal when pressing the clutch—there’s no clutch to press here. If there’s a bearing-type whine or rumble, common checks are:

• CVT health: fluid condition (Nissan NS-3 only), software updates, and driveline mounts. Persistent whine under load may need professional diagnosis for internal CVT bearings.
• Front-end ancillaries: alternator, A/C compressor clutch, idler/tensioner pulleys, and water pump can all mimic “bearing noise”.

Helpful upkeep for long life:

1. Stick to the correct CVT fluid (NS-3). Many workshops in AU/NZ recommend inspection around 60,000–90,000 km, or earlier in heavy traffic/towing conditions. Avoid power flushing, use measured drain-and-fill procedures.
2. Keep engine and transmission mounts in good nick—excess movement can amplify drivetrain noise.
3. If the vehicle has judder, harsh engagement, or a rising whine with road speed, have it scanned for CVT codes and line pressure data before replacing parts.

For engine builders: the MR20DD’s crankshaft thrust bearing function is integrated at the specified main journal, endplay is measured and set per the EM section of the Nissan service manual. This isn’t part of routine servicing and is only handled during engine rebuilds.

Technical sources referenced: Nissan Serena C27 Service Manual (2016–2019) TM–CVT and EM sections, Nissan FAST/Parts Catalogue for C27, Jatco RE0F10D/JF016E (Xtronic CVT) design overviews noting torque converter fitment.

Does a 2017 Nissan Serena have a thrust-bearing?

No clutch-type thrust/release bearing is fitted because the C27 runs an Xtronic CVT with a torque converter. The only “thrust bearings” involved are internal to the engine (crankshaft thrust surfaces) and within the CVT assembly, which aren’t standalone service items.

What should be checked if there’s a bearing-like whine on a Serena?

Rule out ancillaries first: alternator, A/C compressor clutch, idler and tensioner pulleys. Then have a specialist check CVT fluid condition (NS-3), software, mounts, and listen for noises that track road speed or load. Internal CVT bearing issues need professional diagnosis and, if confirmed, an overhaul.

When should the CVT fluid be changed on a 2017 Serena?

Use Nissan NS-3 only. Many AU/NZ workshops inspect around 60,000–90,000 km depending on use (stop–start, heat, hills, towing). Replace if discoloured or contaminated, and avoid power flushes—use proper drain-and-fill and level set procedures per the Nissan service manual.
