Parts for your 2008 Nissan Primera-Thrust bearing

2008 Nissan Primera thrust bearing: fitted on manuals, not on CVT/auto

Based on technical references for the P12-series Nissan Primera (Nissan Electronic Service Manual and the Nissan FAST parts catalogue), manual-transmission models are fitted with a clutch release bearing, commonly called a thrust bearing. It sits on the gearbox input shaft and presses the clutch diaphragm when the pedal’s pushed. CVT/automatic Primera variants don’t use a clutch release/thrust bearing, as they have a torque converter/CVT assembly instead. Separately, the engine’s crankshaft runs thrust washers/bearing faces within the main bearings, but those aren’t routine service items and aren’t what most parts catalogues list under “thrust bearing” for this model.

For a 2008-registered Nissan Primera with a manual gearbox, the thrust bearing’s job is simple but critical: it lets the clutch engage and disengage smoothly by allowing axial load on the pressure plate without chewing out rotating components. When healthy, shifts feel clean and the pedal is quiet. When worn, it can groan or squeal when the pedal is pressed, and gear changes can get notchy.

Best practice on this car is to replace the thrust bearing whenever the clutch is out, typically as part of a complete clutch kit (pressure plate, friction disc, release/thrust bearing). Labour to access the clutch is the big cost, so doing the lot in one hit saves a second teardown. On higher-kilometre vehicles, it’s also sensible to inspect the release fork and pivot, check the guide tube for scoring, and lightly lubricate the bearing’s contact points with the specified high-temp grease—never overdo it, as excess grease can contaminate the friction plate.

Because the Primera P12 uses a hydraulic clutch on most trims, a spongy pedal or poor release can sometimes be down to air or a leaking slave cylinder rather than the thrust bearing. Bleed the system and inspect hydraulics before condemning the bearing. Good driving habits help longevity: don’t rest a foot on the pedal at lights, avoid holding the car on the clutch on hills, and keep clutch engagement smooth rather than slipping it for ages.

Typical signs it’s time to book in:

• Squeal, chirp, or growl with the clutch pedal depressed
• Vibration or roughness felt through the pedal
• Hard shifting or gears clashing despite proper hydraulic operation

For CVT/automatic Primeras, there’s no clutch thrust bearing to service, focus instead on scheduled transmission fluid changes with the correct Nissan-approved CVT/ATF.

FAQs

Do CVT or automatic 2008 Nissan Primeras have a thrust bearing?
No. CVT and automatic variants don’t use a clutch release (thrust) bearing because they don’t have a manual clutch. They use a torque converter or CVT unit. Any “thrust” function in those drivetrains is handled internally and isn’t a routine service item.

What symptoms point to a failing thrust bearing on a Primera?
Noises when the pedal is pressed—squeal, chirp, or rumble—are classic. Add in a rough-feeling pedal or difficulty engaging gears. If noise only occurs with the pedal down and disappears when it’s released, the release/thrust bearing is a prime suspect.

Should the thrust bearing be replaced with the clutch?
Yes. Because the gearbox has to come out, the thrust bearing is replaced as part of a clutch kit. It’s cost-effective and reduces the chance of having to pull the box again shortly after.
