Parts for your 2005 Nissan Primera-Thrust bearing

2005 Nissan Primera thrust-bearing: what’s fitted and how to look after it

Technical documentation confirms a thrust-bearing is relevant on manual 2005 Nissan Primera models. Nissan’s Primera P12 workshop manual (sections CL – Clutch and MT – Manual Transmission) specifies a clutch release (thrust) bearing, and the Nissan FAST electronic parts catalogue lists it for the P12. Common aftermarket clutch kits for the 2005 Primera (e.g., Exedy applications for the P12 1.8/2.0) also include a release/thrust bearing. For CVT-equipped Primeras, a clutch thrust-bearing is not used, because those vehicles employ a torque converter and CVT pulley system rather than a manual clutch.

On manual 2005 Nissan Primeras, the thrust-bearing (often called the clutch release bearing) sits on the gearbox side of the clutch and lets the rotating clutch assembly and the non-rotating fork/hydraulics play nicely together. When the driver presses the clutch, the bearing pushes on the pressure plate’s diaphragm fingers, taking the axial load while spinning smoothly. That lets the pressure plate release the friction disc so gears can be selected without graunching.

It’s not a “service-and-grease” item, it’s sealed and runs clean. The smart move is to replace it whenever the gearbox is out, ideally as part of a complete clutch kit. If the bearing’s tired, common signs include a whirring, chirp, or growl with the pedal pressed, a rough or notchy feel at the pedal, and sometimes trouble selecting gears at a standstill. Noise that appears only when the pedal is down typically points to the release bearing, noise with the pedal up can be input shaft bearing or other drivetrain bits. A proper diagnosis under the bonnet saves guesswork.

When doing a clutch on a Primera, it’s good practice to: replace the thrust-bearing with the clutch disc and pressure plate, inspect or replace the spigot/pilot bush, check the clutch fork, pivot, guide tube and the slave cylinder, lightly lube the input splines and the bearing sleeve with a high-temp moly grease (never the bearing face or friction surfaces), torque everything to spec, and bleed the hydraulics. Many workshops will also resurface the flywheel and check the rear main seal while they’re in there. After fitment, a gentle 300–500 kilometres of driving helps bed-in the new clutch. On CVT models, there’s no external clutch thrust-bearing to service or replace, so any shudder or noise is handled through CVT-specific diagnostics rather than clutch work.

• Typical symptoms of a worn thrust-bearing: noise with pedal down, vibration at the pedal, and difficult gear engagement.
• Best practice: replace the thrust-bearing whenever the transmission is removed, even if it seems “okay”.

Does a 2005 Nissan Primera with CVT have a thrust-bearing?

No. CVT-equipped Primeras don’t use a manual clutch, so there’s no clutch thrust-bearing to service. They rely on a torque converter and CVT pulleys, with very different maintenance needs.

What are the signs the thrust-bearing is failing on a manual Primera?

Listen for a whirring, chirp, or growl that appears when the clutch pedal is pressed and fades when it’s released. You might also feel a rough pedal or find it harder to slot gears at a stop. Get it checked early to avoid collateral wear.

Should the thrust-bearing be replaced with the clutch?

Absolutely. It’s standard practice to replace the thrust-bearing whenever the clutch is done. It adds little cost versus the labour to pull the gearbox again, and helps ensure a smooth, quiet pedal and long clutch life.
