Parts for your 2002 Nissan Navara-Thrust bearing

2002 Nissan Navara thrust-bearing: what it is and how to look after it

Based on technical references including the Nissan D22 Navara (Frontier) Factory Service Manual (CL – Clutch, EM – Engine Mechanical) and major clutch catalogues from Exedy Australia and OE bearing suppliers (NSK/NTN), the 2002 Nissan Navara with a manual gearbox is fitted with a clutch release (thrust) bearing. Automatic models don’t use a clutch thrust-bearing, though all engines still have crankshaft thrust bearings inside the block.

On a manual 2002 Navara, the thrust-bearing sits on the clutch fork and presses against the diaphragm spring of the pressure plate when the clutch pedal’s pushed. Its job is to turn the pedal’s push into a smooth, low-friction axial load so the clutch can disengage cleanly. When it’s healthy, shifts are slick and quiet. When it’s tired, expect a growl or squeal with the pedal down, a notchy engagement, or pedal vibration.

Best practice is to replace the thrust-bearing any time the gearbox is out, especially when fitting a new clutch kit. It’s a relatively cheap part compared to the labour of pulling the transmission. Most good kits for the D22 include a pressure plate, friction disc, thrust-bearing and a spigot bearing. While you’re there, check the clutch fork, pivot ball, release bearing carrier, retaining clip, and the external slave cylinder for leaks or a lazy return. Lightly lubricate the input shaft splines and the fork contact points with a high-temp moly grease—sparingly—keeping grease well away from the friction surfaces.

There’s no fixed service interval for a thrust-bearing, life depends on driving style, towing, off-road work, and clutch habits. A Navara that tows or sees beach tracks may need attention earlier. If any noise appears only with the pedal depressed, that’s a classic hint the thrust-bearing is on the way out. If the noise is present with the pedal up and vanishes when pressed, look at the gearbox input bearing instead.

During refit, align the clutch properly, inspect the flywheel face for heat spots or cracks, and replace the spigot bearing in the crank. Bleed the hydraulic system thoroughly and confirm a smooth pedal with proper engagement point. Always follow the D22 FSM for specs and procedures to avoid premature wear or misalignment.

• Replace thrust-bearing with every clutch job
• Inspect fork, pivot, carrier and slave cylinder
• Use minimal, correct grease only on specified contact points

Popular questions

How can they tell the thrust-bearing is failing on a 2002 Navara?
Most often it’s a chirp, squeal, or rumble that appears when the clutch pedal is pressed and fades when it’s released. Drivers may also feel a buzz through the pedal or notice rough engagement. If the sound is there with the pedal up and disappears when pressed, that points more to the gearbox input shaft bearing than the thrust-bearing.

Do automatic 2002 Navaras have a thrust-bearing?
No clutch thrust-bearing is used on autos because there’s no manual clutch to disengage. Automatics rely on a torque converter. The engine still uses crankshaft thrust bearings internally, but those are separate from the clutch release bearing used on manuals.

Should the thrust-bearing be greased during installation?
The bearing itself is sealed and not serviceable. Do not pack it with grease. Only apply a light smear of high-temp moly grease to the input shaft splines, the fork pivot and fork-to-bearing contact points, exactly as outlined in the D22 FSM. Excess grease can fling onto the clutch disc and cause slip or shudder.
