Parts for your 1994 Nissan Primera-Centre bearing

1994 Nissan Primera centre-bearing — is it even a thing?

Short answer: for a 1994 Nissan Primera (P10), a tailshaft centre-bearing isn’t a thing. The Primera is a front‑wheel‑drive layout, so there’s no long propeller shaft running down the centre of the car that would need a centre support bearing. This is backed by the Nissan Primera P10 Factory Service Manual (Front Axle/Driveline sections), which details front driveshafts and an intermediate shaft, but no propeller shaft, the Nissan FAST electronic parts catalogue for P10 lists an intermediate shaft with its own carrier bearing, not a tailshaft centre support, and the Haynes Primera manual (1990–1999) also describes the model as FWD with a transaxle and equal‑length shafts.

What sometimes causes the confusion is the right‑hand intermediate shaft. It’s braced to the engine block with a carrier/support bearing. Some folks call that a “centre bearing,” but it’s not the same part used on rear‑ or all‑wheel‑drive cars with a two‑piece tailshaft. On a typical AU/NZ or UK‑spec 1994 Primera, that tailshaft‑style centre-bearing simply doesn’t exist.

Why isn’t one used? Because the Primera’s gearbox (transaxle) sits up front and sends power straight to the front wheels with short driveshafts. Centre-bearings are for long, two‑piece tailshafts found in utes, vans and many RWD/4WD platforms. Unless you’ve got an obscure JDM 4WD variant (rare in our market), there’s nothing under the floor needing a centre support.

If you’re chasing vibrations or a droning noise and were told it’s a “centre-bearing,” it’s more likely one of these FWD usual suspects:

• Worn inner CV joints or outer CVs clicking on lock
• A tired intermediate shaft carrier (support) bearing on the RHS
• Engine or gearbox mounts sagging and changing driveline angles
• Out‑of‑balance wheels, flat‑spotted tyres, or a bent rim

Practical tip: with the car safely raised, check for play in the right‑hand intermediate shaft where it’s supported by the bracket—there should be minimal movement and no grinding feel when rotated by hand. Any rumble or slop points to the carrier bearing, not a mythical tailshaft centre-bearing. When in doubt, quote the VIN and ask for the “intermediate shaft carrier bearing” to avoid parts mix‑ups.

Popular questions

Does a 1994 Nissan Primera have a centre-bearing?
For AU/NZ and UK FWD P10 models, no. There’s no tailshaft, so there’s no tailshaft centre-bearing. The car does have an intermediate shaft carrier bearing on the right‑hand driveshaft, which some people casually call a centre bearing, but it’s a different part and purpose.

What causes vibration on my 1994 Primera if it’s not the centre-bearing?
Common culprits include inner CV joint wear, a failing intermediate shaft carrier bearing, or soft engine/gearbox mounts. Don’t overlook wheel balance and tyre condition. A road test under load, then a check on a hoist, usually isolates which side or component is acting up.

How do I check or replace the intermediate shaft carrier bearing?
With the car safely supported, feel for radial play at the bearing and listen for rumble when spinning the shaft by hand. Replacement involves removing the RH driveshaft and intermediate shaft, pressing the old bearing off/on, and refitting the bracket to the block to spec. If you don’t have a press, a driveline shop can handle it quickly.
