Parts for your 2006 Nissan Serena-Thrust bearing

2006 Nissan Serena thrust-bearing: what’s actually fitted and what owners should know

Based on Nissan’s own technical literature for the C25 series Serena (service manual sections TM and CL), the 2006 model with the MR20DE engine is paired with an Xtronic CVT that uses a torque converter, not a manual clutch. Because there’s no clutch, there’s no clutch thrust/release bearing to service. Nissan FAST electronic parts catalogues for CVT-equipped C25 vehicles likewise don’t list a separate clutch release or thrust bearing. The MR20DE engine does have crankshaft thrust bearing surfaces integrated with the main bearings (engine manual, crankshaft section), but those are internal engine components addressed only during a rebuild, not routine servicing.

So, for a typical 2006 Nissan Serena on Aussie or Kiwi roads—most being JDM imports with CVT—a standalone “thrust-bearing” isn’t a relevant service part. The CVT’s torque converter handles take-off and creep, removing the need for a clutch or its release/thrust bearing. If someone’s chasing a “thrust bearing noise”, it’s usually a case of mistaken identity when applied to this vehicle.

Owners keen to keep their Serena happy should focus on CVT health and general driveline checks rather than hunting for a non-existent clutch thrust bearing. Practical tips include:

• Use the correct CVT fluid (NS-2 for most 2006 JF011E/RE0F10A applications) and service on condition—overheating or dark, burnt fluid means it’s due.
• Keep the CVT cooler and radiator clean, heat is the enemy of CVTs.
• Investigate whines or shudders early—these can point to CVT belt/pulley issues or torque converter concerns.
• Rule out lookalike noises: auxiliary belt idlers, A/C compressor clutch, and worn engine mounts can mimic “bearing” sounds.

There were manual-gearbox Serenas in some markets, those do use a clutch release (thrust) bearing. They’re uncommon in Australia and New Zealand, but if the vehicle does have a clutch pedal, then the usual clutch-release-bearing checks apply: listen for growling when the pedal’s down, replace the bearing whenever the clutch is out, and use quality parts.

If the engine is ever rebuilt, the crankshaft’s thrust bearing faces (part of the main bearing set) should be measured for end float and renewed per the engine manual. That’s precision work—best left to a competent engine reconditioner.

Popular questions

Does a 2006 Nissan Serena have a clutch thrust (release) bearing?
Most 2006 Serenas run an Xtronic CVT with a torque converter, so there’s no clutch and no clutch thrust/release bearing to service. Nissan’s C25 service documentation and parts catalogues confirm this for CVT models. If the vehicle has a manual gearbox (rare in our region), then yes, it will have a release/thrust bearing.

What noises are often mistaken for a thrust bearing on a CVT Serena?
On CVT models, common culprits are CVT pulley/belt whine, torque converter chatter, worn auxiliary belt idlers, or an A/C compressor clutch. Engine mounts can also transmit odd vibrations. A workshop familiar with Jatco JF011E/RE0F10A units can pinpoint the source quickly.

Are there thrust bearings inside the MR20DE engine?
Yes, the crankshaft’s axial control is handled by thrust bearing surfaces integrated with the main bearings. They’re internal and only addressed during engine overhaul. They aren’t part of routine servicing like oil or filter changes.
