Parts for your 2014 Nissan Navara-Centre bearing

2014 Nissan Navara centre-bearing — what it does and when to replace it

Based on technical sources including the Nissan Navara D40/D23 Service Manuals (Driveline/Propeller Shaft sections), Nissan FAST parts catalogues, and AU/NZ aftermarket application data from driveline specialists (e.g., Hardy Spicer, GMB), a centre-bearing is fitted to most 2014 Navara models that use a two‑piece tailshaft — typically dual‑cab and many 4x4 variants. Some short‑wheelbase 4x2 single‑cab variants may run a one‑piece tailshaft and won’t have a centre-bearing. For a 2014 dual‑cab/4x4 Navara, a centre-bearing is relevant and commonly serviced.

The centre-bearing (centre support bearing) sits mid‑way along the two‑piece tailshaft, bolted to a crossmember. Its job is to support the shaft, keep driveline angles happy, and tame vibration as torque heads from the gearbox to the diff. On a working ute that tows, carries gear, or sees corrugations and rutted tracks, the rubber isolator and bearing cop plenty of punishment.

When it’s tired, the Navara will often show a rumble or shudder on take‑off, vibration at 60–100 km/h, or a dull clunk as load comes on and off. A visual check can reveal torn rubber, sag around the support, or rust dust/grease fling. Spinning the shaft by hand (with the ute safely supported) may reveal roughness or play.

• Inspection tips: Look for cracked or separated rubber around the support, misalignment of the tailshaft, or contact marks on the hoop. Check the adjacent unis/guibos at the same time.
• Replacement pointers: Mark tailshaft phasing before removal, follow workshop manual torque specs, and consider renewing companion hardware. If the truck has a lift or altered ride height, have the driveline angles checked and the shaft balanced after refit.
• Aftercare: Road‑test under light and moderate throttle, listening for any lingering vibration. Recheck fasteners after a few hundred kays.

Service cadence really depends on use. Heavy towing, beach work, and muddy or dusty tracks shorten bearing life. Many owners choose an OE‑quality or heavy‑duty replacement
