Parts for your 1992 Nissan Primera-Centre bearing

1992 Nissan Primera centre-bearing: is it actually a thing?

For a typical 1992 Nissan Primera (P10) as found in Australia and New Zealand, a driveline centre-bearing isn’t fitted and isn’t relevant. The standard Primera is front‑wheel drive, so there’s no long two‑piece tailshaft running to the back of the car that would need a centre support bearing. Instead, it uses two front driveshafts with CV joints, plus an intermediate shaft on the right‑hand side that’s supported by a small carrier bearing bolted to the engine block. That carrier bearing is sometimes confused with a “centre-bearing”, but they’re different parts doing different jobs.

Why it’s not used comes down to the layout. A centre-bearing supports the middle of a long, two‑piece propeller shaft on rear‑ or all‑wheel drive vehicles, keeping the shaft steady and reducing vibration under load. The 1992 Primera’s transverse engine and transaxle send power straight to the front wheels via short half‑shafts, so there’s no long tailshaft to support, and therefore no need for a centre-bearing.

There is one notable exception: certain Japanese‑market 4WD P10 variants (rare in AU/NZ) do have a rear propeller shaft with a centre support bearing. If the car is a 4WD import, that setup applies. A quick visual check (rear differential present, tailshaft running down the centre tunnel) or verifying the driveline code on the build plate will confirm it.

Technical sources that back this up:

• Nissan Primera P10 Factory Service Manual (FSM): Front Axle/Driveline sections show FWD driveshafts with an intermediate (carrier) bearing, the Propeller Shaft section applies only to 4WD models.
• Nissan FAST electronic parts catalogue: No centre support bearing listed for 2WD P10, a centre bearing assembly is listed only for specific 4WD P10 variants.
• Haynes Nissan Primera (1990–1996) manual: Describes the FWD transaxle layout with no tailshaft on 2WD models.

What owners usually feel when they suspect a “centre-bearing” on a FWD Primera—shudder on take‑off, vibration, or a humming noise—often traces back to worn engine/gearbox mounts, tired inner CV joints, or the intermediate shaft’s carrier bearing. A competent mechanic can isolate that quickly. If it turns out to be the intermediate shaft bearing, replacement involves removing the right‑hand driveshaft assembly, unbolting the bracket, and pressing the bearing off/on—far simpler than tailshaft work.

Got a 4WD import Primera? Then yes, it will use a centre support bearing on the tailshaft. Usual warning signs are a thump on take‑up, vibration at road speed, or a split rubber isolator. Replacement typically involves removing the tailshaft, marking flanges for alignment, pressing the bearing, and refitting to the torque specs in the FSM. Regular inspections at service time—looking for perished rubber and checking for play—will keep it sweet for the long haul.

Popular questions

Does a 1992 Nissan Primera have a centre-bearing?
For the common 2WD P10 Primera, no. It’s a FWD setup with no tailshaft, so there’s no centre-bearing. If it’s a rare 4WD Japanese‑market model, then it does have a centre support bearing on the prop shaft.

What’s the difference between a centre-bearing and the Primera’s intermediate shaft bearing?
The centre-bearing supports a long, two‑piece tailshaft in RWD/4WD vehicles. The Primera’s intermediate (carrier) bearing supports the short right‑hand driveshaft where it bolts to the engine block. Different parts, different locations, different jobs.

How can someone tell if their 1992 Primera is the 4WD model that uses a centre-bearing?
Look underneath: a rear differential and a tailshaft running down the centre tunnel means 4WD and a centre-bearing. No rear diff and no tailshaft means 2WD, so no centre-bearing. The build plate driveline code or a workshop familiar with P10s can confirm.
