Parts for your 2008 Nissan Navara-Thrust bearing

2008 Nissan Navara thrust-bearing: what it does and when to replace it

Referencing the Nissan Navara D40 Workshop Manual (CL – Clutch) and major clutch catalogues used in Australia/NZ (e.g., Exedy and Sachs), the 2008 Navara with a manual gearbox is fitted with a clutch release bearing, commonly called a thrust-bearing. On most D40 manuals it’s integrated into a hydraulic concentric slave cylinder (CSC) inside the bellhousing. Earlier D22 manuals use a conventional release (thrust) bearing operated by a fork and an external slave. Automatic Navaras don’t have a clutch thrust-bearing because they use a torque converter, the engine’s crankshaft thrust washers exist but aren’t routine service items.

On the manual 2008 Navara, the thrust-bearing’s job is simple but crucial: when the driver presses the pedal, hydraulic pressure moves the bearing against the clutch diaphragm spring to disengage the clutch. It needs to spin smoothly while carrying axial load, so gear changes feel clean and the ute stays quiet at idle with the pedal down.

• Common signs it’s tired: a chirp or squeal as the pedal is pressed, a rough or notchy pedal feel, clutch drag making gears hard to select, or fluid weeping from the bellhousing on D40s (a failing CSC).
• Checks that help: listen for noise changes with the pedal up vs down, inspect for hydraulic leaks, note any engagement point that’s moving higher over time.

Best practice on a 2008 Navara manual is to replace the thrust-bearing whenever the clutch is out. On D40 models the CSC and bearing are a single assembly, so it’s replaced as a unit. This saves a second gearbox removal and resets the whole release system. Quality parts (OE-equivalent CSC/bearing, pressure plate, disc, and pilot/spigot bearing) and correct fluid spec (DOT 3 or 4 per the manual) matter. There’s no fixed interval, but many see replacement when the clutch is done, often around 150–250,000 km depending on use, towing, and off-road work.

During service, bleed the hydraulic system properly, avoid resting a foot on the pedal, and if it’s a D22-style setup, check the fork, pivot ball, and guide tube for wear. Always follow workshop torque specs and alignment procedures noted in the Nissan manual to keep the release bearing running smooth and quiet.

• Replace with the clutch to avoid duplicate labour (gearbox removal).
• Inspect/replace pilot bearing and check flywheel surface while in there.
• Flush clutch hydraulics and check for leaks after bleeding.

FAQs

Does a 2008 Navara automatic have a thrust-bearing?
No. Automatic variants use a torque converter, so there’s no clutch release (thrust) bearing. The engine still has crankshaft thrust washers inside the bottom end, but those aren’t part of regular servicing.

How long should the Navara’s thrust-bearing/CSC last?
It varies with driving, load, and maintenance. Many last until the first clutch replacement, commonly 150–250,000 km. Heavy towing, lots of stop–start, or contaminated hydraulic fluid can shorten life.

Can the D40’s thrust-bearing be serviced without removing the gearbox?
Not on the D40, because the bearing is integrated with the concentric slave cylinder inside the bellhousing. The gearbox needs to come out. On D22-style setups, the external slave can be serviced easily, but the actual release bearing still requires gearbox removal.
