Parts for your 1999 Nissan Navara-Thrust bearing

1999 Nissan Navara thrust-bearing

Based on technical sources including the Nissan D22 Navara Workshop Manual (CL — Clutch section) and common clutch kit documentation from OE suppliers used in Australia and New Zealand, the 1999 Nissan Navara with a manual transmission is fitted with a clutch thrust-bearing (also called a release or throw-out bearing). Automatic variants don’t use a clutch thrust-bearing. There’s also a separate engine crankshaft thrust bearing inside the block, but when folk talk Navara “thrust-bearing” they almost always mean the clutch item.

On a manual 1999 Navara, the thrust-bearing sits on a carrier that slides along the gearbox input shaft sleeve. When the driver presses the clutch pedal, the slave cylinder moves the fork, pushing the thrust-bearing into the pressure plate’s diaphragm fingers. Its job is to let those fingers spin while the fork movement stays linear, cleanly disengaging the clutch so gears can be selected without graunching. Because it’s a sealed, high-speed bearing working under axial load, smooth operation and correct lubrication of the guide surfaces are critical.

Servicing advice for Navara owners and workshops:

• Replace the thrust-bearing any time the clutch is out. Clutch kits for the D22 (petrol and diesel manuals) typically include a new bearing for this reason.
• Listen for tell-tales: a chirp, squeal, or rumble that appears with the pedal depressed and fades when released usually points to the thrust-bearing. If the noise is there with the pedal up and goes away when pressed, look at the gearbox input or pilot bearing instead.
• With the gearbox removed, lightly lubricate the input shaft guide tube and the bearing carrier contact points with a high-temp moly or lithium complex grease. Don’t over-grease — excess can fling onto the friction plate.
• Inspect the clutch fork, pivot ball, and the carrier for wear, replace worn bits to avoid a notchy pedal feel or uneven release. Check the slave and master cylinders for smooth travel and leaks.
• If the clutch is slipping or shuddering, consider a full kit: cover, disc, thrust-bearing, and pilot bearing, and have the flywheel inspected and resurfaced if needed.
• After refit, bleed the hydraulics properly and confirm free-play and pedal height match the workshop manual specs.

These points align with the Nissan D22 Workshop Manual procedures and OE clutch supplier guidance used across AU/NZ workshops, which recommend bearing replacement during clutch service to avoid repeat labour and to maintain quiet, smooth operation.

Popular questions about 1999 Nissan Navara thrust-bearing

Does an automatic 1999 Navara have a thrust-bearing?

No. Automatics don’t have a clutch assembly, so there’s no clutch thrust-bearing. The term applies to manual models only. If an automatic has noises on take-off, look at the torque converter, flexplate, or drivetrain mounts instead.

What symptoms point to a worn thrust-bearing on a D22 Navara?

A squeal, chirp, or rough rumble that starts when the clutch pedal is pressed and disappears when released is classic thrust-bearing noise. A heavy or notchy pedal, or poor disengagement, can also happen if the bearing carrier or fork is worn or dry.

Should the thrust-bearing be replaced every time the clutch is done?

Yes. It’s best practice to replace the thrust-bearing whenever the clutch is replaced, as recommended in the Nissan workshop procedures and clutch kit guidance. It’s a low-cost part compared to the labour of removing the gearbox again if it fails later.
