Parts for your 2018 Nissan Serena-Thrust bearing

2018 Nissan Serena thrust bearing — is it actually fitted?

Short answer: a conventional clutch thrust/release bearing isn’t used on the 2018 Nissan Serena (C27). This model is built with Nissan’s Xtronic CVT, and in some trims the e-POWER series-hybrid drive — neither layout uses a manual clutch, so there’s no clutch thrust bearing to service or replace. That’s backed by the Nissan C27 Serena service information for the TM (CVT) sections and e-POWER technical briefs, plus model brochures listing Xtronic CVT/e-POWER with no manual transmission option.

Why it’s not used: a clutch thrust/release bearing only exists on manual-transmission vehicles to press the clutch diaphragm spring. The Serena’s Xtronic CVT uses a torque converter and a steel belt between variable pulleys, managed hydraulically, so there’s no clutch assembly that would need a thrust bearing. The e-POWER variant drives the wheels via a single-speed reduction gear from the traction motor, so again, no clutch, no thrust bearing.

Worth noting: the MR-series engine in the Serena does have crankshaft thrust bearings (thrust faces integrated into the main bearings) to control axial crank movement. These are internal engine components, not a routine service item. Replacement is only relevant during a full engine rebuild or if there’s confirmed excessive end float. That’s described in Nissan engine mechanical (EM) service manual sections covering main bearing/thrust clearance checks.

What owners should do instead of chasing a “thrust bearing” fault: if there’s a driveline noise, look to CVT fluid condition, auxiliary belt and pulleys, wheel bearings, or the A/C compressor. Follow the Nissan schedule for CVT fluid (NS-3) checks and replacement based on usage/severity, and use the correct diagnostic procedures in the TM (CVT) section before parts swapping.

• Technical basis and references: Nissan C27 Serena Service Manual (TM: CVT system, EM: engine mechanical), Nissan product brochure/specs indicating Xtronic CVT and e-POWER only, Nissan e-POWER system overview describing single-speed reduction with no clutch.

Popular questions about the 2018 Nissan Serena thrust bearing

Does a 2018 Serena have a clutch thrust/release bearing?
No. The C27 Serena runs Xtronic CVT or e-POWER, so there’s no manual clutch. If a workshop quotes a “thrust bearing” like on a manual, they’re likely mixing it up with another model.

Are there any thrust bearings in the Serena at all?
Yes, but only internally: the engine’s crankshaft uses thrust bearing surfaces as part of the main bearings. These aren’t routine service parts and are only addressed during major engine work with proper end-float measurement.

What noises might be mistaken for a bad thrust bearing on a Serena?
Common red herrings include CVT whine under load, dry auxiliary idler/tensioner pulleys, an A/C compressor clutch rattle, or a worn wheel hub bearing. Proper diagnosis per the TM section is the go before replacing anything.
