Parts for your 2008 Nissan Serena-Thrust bearing

2008 Nissan Serena thrust-bearing — is it actually a thing on this model?

For the 2008 Nissan Serena (C25 series), a clutch “thrust-bearing” (often called a release bearing) is not fitted on the vast majority of vehicles because this model is equipped with an Xtronic CVT with a torque converter rather than a manual clutch. Technical documentation covering the C25 Serena’s transmission confirms it uses the RE0F10A/JF011E CVT, which does not have a clutch release/thrust bearing like a manual gearbox would. This setup is detailed in Nissan’s C25 factory service manual (Transmission, CVT section) and Jatco’s service literature for the JF011E unit.

Under the bonnet, the Serena’s MR20DE petrol engine does have a thrust-bearing function, but it’s built into the crankshaft main bearing set to control end-float. That’s an internal engine component, not a routine service item. The Engine Mechanical (EM) section of Nissan’s MR20DE service manual outlines the crankshaft end-play control via thrust surfaces in the main bearings. Similarly, the CVT contains internal thrust washers/bearings that support axial loads inside the transmission, but these are only touched during a specialist overhaul — not normal servicing.

Why it’s not used like on a manual: with a torque converter-CVT, drive take-up is handled hydraulically through the converter and CVT pulleys, so there’s no clutch pressure plate or release mechanism. That’s why there’s no external, serviceable clutch thrust/release bearing on a 2008 Serena.

• Clutch thrust/release bearing: Not applicable on CVT-equipped 2008 Serena models.
• Engine thrust-bearing surfaces: Present inside the MR20DE main bearings, checked only during engine rebuild procedures.
• CVT internal thrust components: Present, but only serviced during a transmission overhaul.

For Aussie and Kiwi owners (many vehicles are JDM imports), the practical takeaway is simple: there’s no thrust-bearing to replace as part of routine servicing on a 2008 Serena. Focus instead on timely CVT fluid changes with the correct spec (commonly Nissan NS-2 for the JF011E generation — always verify against the vehicle’s build data) and general driveline inspections. If there’s noise that sounds “bearing-like,” a technician should differentiate between CVT pulley/bearing whine, torque converter noise, or engine accessory bearings rather than chasing a non-existent clutch release bearing.

FAQs

Does a 2008 Nissan Serena have a clutch thrust/release bearing?
Generally, no. The C25 Serena uses an Xtronic CVT with a torque converter, so there’s no manual clutch and no release (thrust) bearing to service. Only very rare manual variants in other platforms use a release bearing, and these are not typical for 2008 Serena imports in Australia or New Zealand.

Where is the thrust-bearing on the MR20DE engine?
It’s integrated into the crankshaft main bearing assembly as thrust faces that control end-float. It’s an internal engine component addressed during overhaul procedures, not something replaced during regular servicing.

I can hear a bearing noise — could it be a thrust-bearing?
On a CVT Serena, unlikely. A whine or rumble when driving may point to CVT pulley bearings or the torque converter, a rattle could be from ancillary components or mounts. A qualified technician can isolate the source before any parts are ordered.
