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, pairing the job with new universals (if serviceable type) is good value. Because fitment varies by wheelbase and drivetrain, confirm by VIN/build plate whether your 2014 Navara has a two‑piece tailshaft with a centre-bearing, especially on single‑cab 4x2 models.

Popular questions

Does every 2014 Navara have a centre-bearing?
Not all of them. Dual‑cab and most 4x4 variants use a two‑piece tailshaft with a centre support bearing. Some short‑wheelbase 4x2 single‑cabs run a one‑piece tailshaft and won’t have one. The quickest check is to look under the ute for a mid‑shaft support bracket or confirm by VIN and driveline code.

What are the common symptoms of a failing centre-bearing on a 2014 Navara?
Shudder on take‑off, vibration around highway speeds, and a clunk as you get on or off the throttle. A sagging or torn rubber support and roughness when rotating the shaft by hand are red flags. Always check the universal joints as they can mimic the same symptoms.

Is it safe to keep driving with a worn centre-bearing?
Short term, light driving might be possible, but it’s risky. A failing centre-bearing can accelerate wear on unis, seals, and mounts, and severe cases can damage the tailshaft. It’s best to book it in promptly and avoid heavy loads or high speeds until it’s sorted.
