Parts for your 2005 Nissan Navara-Centre bearing

2005 Nissan Navara centre-bearing — what it does and when to sort it

Based on Nissan’s workshop manuals for the D22 and D40 platforms (propeller shaft/tailshaft sections) and Nissan FAST electronic parts catalogues for 2005 model-year Navara/Frontier, the dual-cab and most long‑wheelbase 4x4/4x2 variants run a two‑piece tailshaft with a centre support bearing. Certain short‑wheelbase 4x2 single cabs use a one‑piece shaft and don’t have a centre-bearing. For most 2005 Navaras on Aussie and NZ roads, a centre-bearing is fitted and is a normal wear item.

The centre-bearing (centre support bearing) sits mid-way along the two‑piece tailshaft. Its job is to support the shaft, control angles under load, and keep everything running smooth when the ute squats, tows, or tackles rough surfaces. It reduces vibration, protects the universal joints, and helps the diff and gearbox live a happier life by keeping driveline geometry in check.

On a 2005 Navara, tell‑tale signs it’s time for attention include shudder on take‑off, a droning or humming around 60–80 km/h, a clunk when shifting from reverse to drive, or visible cracking/sagging of the rubber mount. Excess play when the tailshaft is lifted by hand near the bearing is another giveaway. Lifted suspensions or heavy towing can accelerate wear because driveline angles change and load the rubber carrier more.

Replacement is straightforward for a trained tech: mark the tailshaft halves for phasing, drop the shaft, press the old bearing off, and install the new bearing in the correct orientation. It’s smart to inspect the universal joints and slip yoke splines at the same time—if they’re worn, doing them together saves a second trip under the ute. Fasteners should be torqued to spec from the Nissan manual, and the shaft refitted in its original alignment to avoid new vibrations. Aftermarket quality varies, so choosing an OE‑equivalent bearing and bracket pays off in longevity and noise control.

As for servicing, the centre-bearing isn’t a periodic replacement item, but it’s worth a check at each service or tyre rotation: look for perished rubber, leaks from the gearbox or diff that might contaminate the rubber, and any contact marks suggesting the shaft has been rubbing. If the Navara has a lift, consider a driveline angle check or a centre-bearing spacer kit where appropriate, to keep the tailshaft running sweet and vibration‑free.

• Common symptoms: shudder on launch, mid‑speed drone, rubber cracks/sag, clunks on load change.
• Best practice: replace on condition, verify tailshaft phasing, check U‑joints and mounts together.
• Tools/notes: press for bearing swap, torque to manual specs, avoid mixing shaft orientations.

Popular questions about 2005 Nissan Navara centre-bearing

Do all 2005 Navaras have a centre-bearing?

Not all. Technical references for the D22 and D40 show most dual‑cab and long‑wheelbase variants use a two‑piece tailshaft with a centre-bearing, while some short‑wheelbase 4x2 single cabs run a one‑piece shaft without one. A quick look underneath will confirm it—two shaft sections with a bracket in the middle means there’s a centre-bearing.

Is it safe to drive with a noisy or sagging centre-bearing?

Short trips at low speed might be possible, but it’s not recommended. A failing centre-bearing can let the tailshaft move around, accelerating U‑joint wear and potentially causing severe vibration. Left too long, it can damage the gearbox output seal or diff pinion seal. It’s best to book it in as soon as the symptoms appear.

What else should be replaced when doing the centre-bearing?

Many owners choose to inspect and, if needed, replace the rear gearbox mount and any tired U‑joints at the same time. If the Navara has a lift or a history of towing, checking tailshaft phasing and driveline angles during the job helps prevent a return of vibrations.
