Parts for your 1997 Nissan Navara-Centre bearing

1997 Nissan Navara Centre-Bearing — Fitment, Purpose, and Service Tips

For the 1997 Nissan Navara sold in Australia and New Zealand, a centre-bearing (also called a centre support or carrier bearing) is used on models with a two-piece tailshaft — typically dual-cab and long wheelbase utes in both 2WD and 4WD. Short wheelbase single-cab variants often run a one-piece tailshaft and therefore do not have, or need, a centre-bearing. This means the part is relevant to most 1997 Navaras with a two-piece shaft, but not to one-piece shaft vehicles.

Technical sources supporting this include: Nissan Navara D22 Workshop Manual (Propeller Shaft/PD section: two-piece shaft with centre bearing), Nissan Hardbody D21 Service Manual (Propeller Shaft section noting centre support on two-piece shafts), major bearing catalogues (NTN/SKF) and local parts catalogues (Burson/Repco) listing centre support bearings for D21/D22 dual-cab and LWB applications.

On Navaras that have one, the centre-bearing’s job is to support the two-piece tailshaft, keeping it aligned under load and at speed. It helps control driveline angles, reduce vibrations, and isolate noise, especially in long wheelbase and dual-cab layouts where a one-piece shaft would be too long and prone to whip. When the rubber isolator perishes or the bearing wears, the ute can develop a take-off shudder, a mid-range vibration (often around 40–80 km/h), clunks on throttle changes, or a droning/rumbling noise that rises with road speed.

Good servicing practice is to inspect the centre-bearing at regular intervals (every 20,000–30,000 km or at each major service). Look for cracked or separated rubber, loose mounting hardware, and any play in the bearing. Also check companion components that affect driveline angles, like engine and transmission mounts, and make sure universal joints are free and correctly phased.

If replacement is due, the tailshaft must be removed. Mark the shaft halves to preserve phasing, then separate them and press the old bearing off the journal. A quality press-fit is essential, many owners opt to have a driveline shop press the new bearing on and balance the assembly. Refit using new hardware where required, torque to the workshop manual, and confirm the hanger bracket sits square so the rubber isn’t preloaded. After any suspension or ride-height changes (lifts, helper springs, heavy loads), recheck driveline angles — incorrect angles can quickly shorten a new bearing’s life.

Using a reputable bearing (OEM-equivalent from a known brand) and addressing worn uni joints at the same time is a smart way to restore smoothness and cut repeat labour. Treated right, a fresh centre-bearing will usually run quietly for many years of Aussie and Kiwi ute duties.

• Typical symptoms: take-off shudder, 40–80 km/h vibration, rumble with speed, clunk on throttle.
• Service tip: inspect at each major service, replace if rubber is cracked or bearing is noisy/loose.
• Fitment note: dual-cab/LWB two-piece tailshafts use a centre-bearing, SWB one-piece tailshafts do not.

Popular questions about 1997 Nissan Navara centre-bearing

How can someone tell if their 1997 Navara actually has a centre-bearing?
Check the tailshaft from the gearbox to the diff. If there’s a support bracket and rubber-mounted bearing roughly mid-way, it’s a two-piece shaft with a centre-bearing. Dual-cab and long wheelbase models commonly have it. Many short wheelbase single-cabs have a single-piece shaft, so there’s no bearing in the middle. When unsure, a quick look underneath or a check of the driveline section in the workshop manual will confirm it.

How often should the centre-bearing be replaced?
There’s no set interval — it’s condition-based. Inspect at every major service. On utes that tow, carry loads, or see rough roads, expect wear sooner. Many last well past 150,000 km, but once the rubber perishes or the bearing rumbles, replacement is due. Address uni joints and driveline angles at the same time to get the best life from the new part.

Can the centre-bearing be replaced at home?
Yes, with the right tools and care. The tailshaft must be removed, the halves marked for phasing, and the old bearing pressed off. A press is usually required, some owners use a driveline shop for pressing and balancing. On refit, align the hanger bracket correctly and torque fasteners to the manual. If any step feels beyond the toolkit, a driveline specialist can do the job quickly and ensure smooth results.
